... 7. A box slides down a smooth slope with an acceleration of 4 m s-2. The velocity of the box at a time t = 0 is 3 m s-1 down the slope. Using a = dv show by integration that the velocity, v, of the box is given by dt v = 3 + 4t. 8. The equation for the velocity, v, of a moving trolley is v = 2 + 6t. ...

Motion in one and two dimensions
... All motions are relative.The motion (velocity) of an object depends on which frame of reference is used to measure it. We say the measured velocity is relative to the chosen frame of reference. Usually the ground is the preferred choice as the reference frame and very often it is not specifically me ...
