Positive Negative Positive Negative Negative Positive s You may want to review ( pages 16 – 19) . For help with math skills, you may want to review: Plotting Points on a Graph Part A Make a position-versus-time graph for the drag racer. Hint 1. How to approach the problem Based on Table 1.1 in the book/e-text, what two observables are associated with each point? Which position or point of the drag racer occurs first? Which position occurs last? If you label the first point as happening at , at what time does the next point occur? At what time does the last position point occur? What is the position of a point halfway in between and ? Can you think of a way to estimate the positions of the points using a ruler? ANSWER: t = 0 s x = 0 m x = 200 m Correct Motion of Two Rockets Learning Goal: To learn to use images of an object in motion to determine velocity and acceleration. Two toy rockets are traveling in the same direction (taken to be the x axis). A diagram is shown of a time-exposure image where a stroboscope has illuminated the rockets at the uniform time intervals indicated. Part A At what time(s) do the rockets have the same velocity? Hint 1. How to determine the velocity The diagram shows position, not velocity. You can’t find instantaneous velocity from this diagram, but you can determine the average velocity between two times and : . Note that no position values are given in the diagram; you will need to estimate these based on the distance between successive positions of the rockets. ANSWER: Correct t1 t2 vavg[t1, t2] = x(t2)−x(t1) t2−t1 at time only at time only at times and at some instant in time between and at no time shown in the figure t = 1 t = 4 t = 1 t = 4 t = 1 t = 4 Part B At what time(s) do the rockets have the same x position? ANSWER: Correct Part C At what time(s) do the two rockets have the same acceleration? Hint 1. How to determine the acceleration The velocity is related to the spacing between images in a stroboscopic diagram. Since acceleration is the rate at which velocity changes, the acceleration is related to the how much this spacing changes from one interval to the next. ANSWER: at time only at time only at times and at some instant in time between and at no time shown in the figure t = 1 t = 4 t = 1 t = 4 t = 1 t = 4 at time only at time only at times and at some instant in time between and at no time shown in the figure t = 1 t = 4 t = 1 t = 4 t = 1 t = 4 Correct Part D The motion of the rocket labeled A is an example of motion with uniform (i.e., constant) __________. ANSWER: Correct Part E The motion of the rocket labeled B is an example of motion with uniform (i.e., constant) __________. ANSWER: Correct Part F At what time(s) is rocket A ahead of rocket B? and nonzero acceleration velocity displacement time and nonzero acceleration velocity displacement time Hint 1. Use the diagram You can answer this question by looking at the diagram and identifying the time(s) when rocket A is to the right of rocket B. ANSWER: Correct Dimensions of Physical Quantities Learning Goal: To introduce the idea of physical dimensions and to learn how to find them. Physical quantities are generally not purely numerical: They have a particular dimension or combination of dimensions associated with them. Thus, your height is not 74, but rather 74 inches, often expressed as 6 feet 2 inches. Although feet and inches are different units they have the same dimension–length. Part A In classical mechanics there are three base dimensions. Length is one of them. What are the other two? Hint 1. MKS system The current system of units is called the International System (abbreviated SI from the French Système International). In the past this system was called the mks system for its base units: meter, kilogram, and second. What are the dimensions of these quantities? ANSWER: before only after only before and after between and at no time(s) shown in the figure t = 1 t = 4 t = 1 t = 4 t = 1 t = 4 Correct There are three dimensions used in mechanics: length ( ), mass ( ), and time ( ). A combination of these three dimensions suffices to express any physical quantity, because when a new physical quantity is needed (e.g., velocity), it always obeys an equation that permits it to be expressed in terms of the units used for these three dimensions. One then derives a unit to measure the new physical quantity from that equation, and often its unit is given a special name. Such new dimensions are called derived dimensions and the units they are measured in are called derived units. For example, area has derived dimensions . (Note that “dimensions of variable ” is symbolized as .) You can find these dimensions by looking at the formula for the area of a square , where is the length of a side of the square. Clearly . Plugging this into the equation gives . Part B Find the dimensions of volume. Express your answer as powers of length ( ), mass ( ), and time ( ). Hint 1. Equation for volume You have likely learned many formulas for the volume of various shapes in geometry. Any of these equations will give you the dimensions for volume. You can find the dimensions most easily from the volume of a cube , where is the length of the edge of the cube. ANSWER: acceleration and mass acceleration and time acceleration and charge mass and time mass and charge time and charge l m t A [A] = l2 x [x] A = s2 s [s] = l [A] = [s] = 2 l2 [V ] l m t V = e3 e [V ] = l3 Correct Part C Find the dimensions of speed. Express your answer as powers of length ( ), mass ( ), and time ( ). Hint 1. Equation for speed Speed is defined in terms of distance and time as . Therefore, . Hint 2. Familiar units for speed You are probably accustomed to hearing speeds in miles per hour (or possibly kilometers per hour). Think about the dimensions for miles and hours. If you divide the dimensions for miles by the dimensions for hours, you will have the dimensions for speed. ANSWER: Correct The dimensions of a quantity are not changed by addition or subtraction of another quantity with the same dimensions. This means that , which comes from subtracting two speeds, has the same dimensions as speed. It does not make physical sense to add or subtract two quanitites that have different dimensions, like length plus time. You can add quantities that have different units, like miles per hour and kilometers per hour, as long as you convert both quantities to the same set of units before you actually compute the sum. You can use this rule to check your answers to any physics problem you work. If the answer involves the sum or difference of two quantities with different dimensions, then it must be incorrect. This rule also ensures that the dimensions of any physical quantity will never involve sums or differences of the base dimensions. (As in the preceeding example, is not a valid dimension for a [v] l m t v d t v = d t [v] = [d]/[t] [v] = lt−1 v l + t physical quantitiy.) A valid dimension will only involve the product or ratio of powers of the base dimensions (e.g. ). Part D Find the dimensions of acceleration. Express your answer as powers of length ( ), mass ( ), and time ( ). Hint 1. Equation for acceleration In physics, acceleration is defined as the change in velocity in a certain time. This is shown by the equation . The is a symbol that means “the change in.” ANSWER: Correct Consistency of Units In physics, every physical quantity is measured with respect to a unit. Time is measured in seconds, length is measured in meters, and mass is measured in kilograms. Knowing the units of physical quantities will help you solve problems in physics. Part A Gravity causes objects to be attracted to one another. This attraction keeps our feet firmly planted on the ground and causes the moon to orbit the earth. The force of gravitational attraction is represented by the equation , where is the magnitude of the gravitational attraction on either body, and are the masses of the bodies, is the distance between them, and is the gravitational constant. In SI units, the units of force are , the units of mass are , and the units of distance are . For this equation to have consistent units, the units of must be which of the following? Hint 1. How to approach the problem To solve this problem, we start with the equation m2/3 l2 t−2 [a] l m t a a = v/t  [a] = lt−2 F = Gm1m2 r2 F m1 m2 r G kg  m/s2 kg m G . For each symbol whose units we know, we replace the symbol with those units. For example, we replace with . We now solve this equation for . ANSWER: Correct Part B One consequence of Einstein’s theory of special relativity is that mass is a form of energy. This mass-energy relationship is perhaps the most famous of all physics equations: , where is mass, is the speed of the light, and is the energy. In SI units, the units of speed are . For the preceding equation to have consistent units (the same units on both sides of the equation), the units of must be which of the following? Hint 1. How to approach the problem To solve this problem, we start with the equation . For each symbol whose units we know, we replace the symbol with those units. For example, we replace with . We now solve this equation for . ANSWER: F = Gm1m2 r2 m1 kg G kg3 ms2 kgs2 m3 m3 kgs2 m kgs2 E = mc2 m c E m/s E E = mc2 m kg E Correct To solve the types of problems typified by these examples, we start with the given equation. For each symbol whose units we know, we replace the symbol with those units. For example, we replace with . We now solve this equation for the units of the unknown variable.

ANSWER: Incorrect; Try Again ± Moving at the Speed of Light Part A How many nanoseconds does it take light to travel a distance of 4.40 in vacuum? Express your answer numerically in nanoseconds. Hint 1. How to approach the problem Light travels at a constant speed; therefore, you can use the formula for the distance traveled in a certain amount of time by an object moving at constant speed. Before performing any calculations, it is often recommended, although it is not strictly necessary, to convert all quantities to their fundamental units rather than to multiples of the fundamental unit. km Hint 2.

Additional Information Remember that a variety of Resources is available to support your learning materials.Skills and character audit This document provides an initial picture of your skills and character. It will also provide the basis of further documents that make up the first assignment on the module. It is based on the skills statements that form a fundamental part of your Masters programme which were approved by a validation panel that consisted of members of staff in the Business School, academic staff from other higher education institutions and employers. The statements in the form are there for you and you will not be judged on whether your responses are positive or negative. The responses should enable you to identify what you are good or bad at from which you can create a personal SLOT analysis (Strengths, Limitations, Opportunities, Threats). From this SLOT analysis you can then concentrate on developing certain areas that will enhance your academic and professional development. We would very much like to” get to know” you through this document and would encourage you to also complete the notes section. In this you could give us a rationale for your responses to the questions. As a guide to how you should gauge your response consider the following: Strongly agree – I have a wide range of experience in this area and have been commended by a tutor or employer for my efforts in this area Agree – I am comfortable with this aspect and have been able to demonstrate my ability Disagree – I am Ok with this but realise that I do need to improve Strongly disagree – I know I am weak in this area and need to focus on this as I could fine this weakness to be detrimental to my progression Explain why – please take the room to consider the reasons for your answer as this is the reflection that is of most value. Do not worry if your section spills onto the next page.   Intellectual (thinking) skills Strongly Agree Agree Disagree Strongly Disagree I am a creative person who can adapt my thinking to circumstances I am able to organise my thoughts, analyse, synthesise and critically appraise situations I can identify assumptions, evaluate statements in terms of evidence, detect false logic or reasoning, identify implicit values, define terms adequately and generalise appropriately Explain why: Professional/Vocational skills Strongly Agree Agree Disagree Strongly Disagree I use a wide range of techniques in approaching and solving problems. I am comfortable with a range of research techniques I am able to analyse and interpret quantitative data I am able to analyse and interpret qualitative data My leadership skills are well developed and I can adapt them to different situations I am able to manage people effectively Motivating myself and others comes easy to me I am aware of my responsibilities to myself, the organisation and other people I treat people with respect and consideration Explain why:   Key/Common skills Strongly Agree Agree Disagree Strongly Disagree I am able to use mathematical techniques to analyse data I can effectively interpret numerical data including tables and charts I am able to use a wide range of software on a PC I use a range Information Technology devices to communicate and access information I am a good listener I am able to communicate my ideas well in a face-to-face situation I can adapt my written style to suit an audiences needs I am comfortable presenting my ideas to an audience Whenever I have completed a task I always reflect on the experience with a view to seeking continuous improvement I manage my time effectively I am always prompt when asked to complete a task I am aware of the need to be sensitive to the cultural differences to which I have been exposed I am keen to learn about other people and their country and culture I enjoy working with others to complete a task I know my own character and am sensitive of this in a group situation I understand that a group is made of individuals and I am sensitive to the needs and preferences of others I will always ensure that I get my views across in a meeting I am willing to accept the viewpoint of others I always give 100% in a group task Explain why: SLOT Analysis Having responded to the statements above you should now be in a position to look forward and recognise those areas on which your development will be based. The SLOT analysis can help you to arrange this. Strengths – can be those skills and characteristics to which you have responded positively to in the previous section. It is worth noting that whilst you may be strong in these areas that does not mean you ignore their development. Indeed you may be able to utilise these strengths in the development of areas identified as weaknesses or to overcome strengths, this will enhance those skills and characteristics. Limitations – All of us can identify some sort of limitation to our skills. None of us should be afraid of doing this as this is the first stage on the improvement and development of these weaknesses. Opportunities – These arise or can be created. When thinking of this look ahead at opportunities that will arise in a professional, academic or social context within which your development can take place. Threats – Many threats from your development can come from within – your own characteristics e.g. poor time management can lead to missing deadlines. However we could equally identify a busy lifestyle as a threat to our development. Once again think widely in terms of where the threat will come from. Do not worry if you find that a strength can also be a limitation. This is often true as a characteristic you have may be strength in one situation but a limitation in another. E.g. you may be an assertive person, which is positive, but this could be negative in a group situation. Please try and elaborate this in the notes section at the foot of the table. SLOT Analysis (you may need to use two pages to set out this analysis) Strengths Limitations Opportunities Threats Analysis of the Bullet points in the SLOT table Objectives Having undertaken some analysis of your skills and characteristics the aim of this next section is to identify various aspects of your development during the course of this module, other modules on your course, and extra-curricular activities. Make sure the objectives are SMART:- S – Specific. Clearly identified from the exercises undertaken M – Measurable. The outcomes can be easily demonstrated (to yourself, and where possible others) A – Achievable. They can be done given the opportunities available to you R – Relevant. They form part of your development either on this award, in your employability prospects or in your current job role T – Timebound. They can be achieved within a given timescale Whilst there are 5 rows in the table below, please feel free to add more. However be sure that you need to do this development and that they fit within the scope of the above criteria. Area What I am going to do. How I am going to do it When I am going to do it by Force Field Analysis This technique was designed by Kurt Lewin (1947 and 1953). In the business world it is used for decision making, looking at forces that need to be considered when implementing change – it can be said to be a specialised method of weighing up the pros and cons of a decision. Having looked at your personal strengths and weaknesses we would like you to use this technique to become aware of those factors that will help/hinder, give you motivation for or may act against, your personal development. Whilst you could do this for each of your objectives we want you to think in terms of where you would like to be at the end of your Masters programme. In the central pillar, put in a statement of where you want to be at the end of the course. Then in the arrows either side look at those factors/forces that may work in your favour.

Additional Information Remember that a variety of Resources is available to support your learning materials.Skills and character audit This document provides an initial picture of your skills and character. It will also provide the basis of further documents that make up the first assignment on the module. It is based on the skills statements that form a fundamental part of your Masters programme which were approved by a validation panel that consisted of members of staff in the Business School, academic staff from other higher education institutions and employers. The statements in the form are there for you and you will not be judged on whether your responses are positive or negative. The responses should enable you to identify what you are good or bad at from which you can create a personal SLOT analysis (Strengths, Limitations, Opportunities, Threats). From this SLOT analysis you can then concentrate on developing certain areas that will enhance your academic and professional development. We would very much like to” get to know” you through this document and would encourage you to also complete the notes section. In this you could give us a rationale for your responses to the questions. As a guide to how you should gauge your response consider the following: Strongly agree – I have a wide range of experience in this area and have been commended by a tutor or employer for my efforts in this area Agree – I am comfortable with this aspect and have been able to demonstrate my ability Disagree – I am Ok with this but realise that I do need to improve Strongly disagree – I know I am weak in this area and need to focus on this as I could fine this weakness to be detrimental to my progression Explain why – please take the room to consider the reasons for your answer as this is the reflection that is of most value. Do not worry if your section spills onto the next page.   Intellectual (thinking) skills Strongly Agree Agree Disagree Strongly Disagree I am a creative person who can adapt my thinking to circumstances I am able to organise my thoughts, analyse, synthesise and critically appraise situations I can identify assumptions, evaluate statements in terms of evidence, detect false logic or reasoning, identify implicit values, define terms adequately and generalise appropriately Explain why: Professional/Vocational skills Strongly Agree Agree Disagree Strongly Disagree I use a wide range of techniques in approaching and solving problems. I am comfortable with a range of research techniques I am able to analyse and interpret quantitative data I am able to analyse and interpret qualitative data My leadership skills are well developed and I can adapt them to different situations I am able to manage people effectively Motivating myself and others comes easy to me I am aware of my responsibilities to myself, the organisation and other people I treat people with respect and consideration Explain why:   Key/Common skills Strongly Agree Agree Disagree Strongly Disagree I am able to use mathematical techniques to analyse data I can effectively interpret numerical data including tables and charts I am able to use a wide range of software on a PC I use a range Information Technology devices to communicate and access information I am a good listener I am able to communicate my ideas well in a face-to-face situation I can adapt my written style to suit an audiences needs I am comfortable presenting my ideas to an audience Whenever I have completed a task I always reflect on the experience with a view to seeking continuous improvement I manage my time effectively I am always prompt when asked to complete a task I am aware of the need to be sensitive to the cultural differences to which I have been exposed I am keen to learn about other people and their country and culture I enjoy working with others to complete a task I know my own character and am sensitive of this in a group situation I understand that a group is made of individuals and I am sensitive to the needs and preferences of others I will always ensure that I get my views across in a meeting I am willing to accept the viewpoint of others I always give 100% in a group task Explain why: SLOT Analysis Having responded to the statements above you should now be in a position to look forward and recognise those areas on which your development will be based. The SLOT analysis can help you to arrange this. Strengths – can be those skills and characteristics to which you have responded positively to in the previous section. It is worth noting that whilst you may be strong in these areas that does not mean you ignore their development. Indeed you may be able to utilise these strengths in the development of areas identified as weaknesses or to overcome strengths, this will enhance those skills and characteristics. Limitations – All of us can identify some sort of limitation to our skills. None of us should be afraid of doing this as this is the first stage on the improvement and development of these weaknesses. Opportunities – These arise or can be created. When thinking of this look ahead at opportunities that will arise in a professional, academic or social context within which your development can take place. Threats – Many threats from your development can come from within – your own characteristics e.g. poor time management can lead to missing deadlines. However we could equally identify a busy lifestyle as a threat to our development. Once again think widely in terms of where the threat will come from. Do not worry if you find that a strength can also be a limitation. This is often true as a characteristic you have may be strength in one situation but a limitation in another. E.g. you may be an assertive person, which is positive, but this could be negative in a group situation. Please try and elaborate this in the notes section at the foot of the table. SLOT Analysis (you may need to use two pages to set out this analysis) Strengths Limitations Opportunities Threats Analysis of the Bullet points in the SLOT table Objectives Having undertaken some analysis of your skills and characteristics the aim of this next section is to identify various aspects of your development during the course of this module, other modules on your course, and extra-curricular activities. Make sure the objectives are SMART:- S – Specific. Clearly identified from the exercises undertaken M – Measurable. The outcomes can be easily demonstrated (to yourself, and where possible others) A – Achievable. They can be done given the opportunities available to you R – Relevant. They form part of your development either on this award, in your employability prospects or in your current job role T – Timebound. They can be achieved within a given timescale Whilst there are 5 rows in the table below, please feel free to add more. However be sure that you need to do this development and that they fit within the scope of the above criteria. Area What I am going to do. How I am going to do it When I am going to do it by Force Field Analysis This technique was designed by Kurt Lewin (1947 and 1953). In the business world it is used for decision making, looking at forces that need to be considered when implementing change – it can be said to be a specialised method of weighing up the pros and cons of a decision. Having looked at your personal strengths and weaknesses we would like you to use this technique to become aware of those factors that will help/hinder, give you motivation for or may act against, your personal development. Whilst you could do this for each of your objectives we want you to think in terms of where you would like to be at the end of your Masters programme. In the central pillar, put in a statement of where you want to be at the end of the course. Then in the arrows either side look at those factors/forces that may work in your favour. Be realistic and please add as many arrows that you think may be necessary; use a separate page for the module if it makes it easier to structure your thoughts.
