1- Define velocity and acceleration in terms of position and time. differentiate between the instantaneous quantities and the average quantities.
2- how are average velocity and instantaneous velocity related for an object moving at constant and non constant velocity?
3-how would you expect the graph of position versus time to look for a car moving at constant and non constant velocity on a track? explain how the graph would be?
4- what would a graph of instantaneous velocity versus time look like for a car moving with constant velocity? or a car speeding up? or if the car is slowing down?
