Question
Use equations to define the following three terms, and explain how they are related yet different from one another average speed average velocity and average acceleration Explain how average speed differs from instantaneous speed average velocity differs from Instantaneous velocity average acceleration offers from instantaneous acceleration Show how and when to use the following three equations to calculate the position, velocity and/or acceleration of any common moving object, or to calculate how much time it moves Show how and when to use the two more complex motion equations Explain what is meant by the acceleration due to gravity symbol 'g' For any object that is freely falling or for any object tossed straight up or down into the air (with no air drag) Describe m words what happens to its position velocity, and acceleration as time goes by Calculate values for its position velocity and acceleration as a function of time For the object described m objective 6 above (falling or tossed) describe how its motion will be different if there is significant air resistance (You don't need to calculate any numbers, just describe in words ) For any common moving object, accurately draw and interpret the following three graphs of its motion You should be able to draw and interpret the three graphs above when the object isExplanation / Answer
Q No. 1
average speed = total distance travelled/ total time
average velocity = total displacement / total time
average acceleration = total change in velocity/ total time
all these quantities are different from each othe. average speed is defined for distance whereas average velocity defined for displacement. average speed is scalar quantity where as average velocity is a vector quantity.
q. No 2
average speed is the speed for a time interval where as instantaneous speed is the speed of a body at a particular instant of time
same for average velocity is definrd for a time interval whereas instantaneous velocity is velocity at a given instant of time.
average acceleration defined for a time interval whereas instantaneous acceleration is velocity at a given instant of time.
