Eg. Average speed = total distance travelled / total time taken. (a) Uniform Velocity (Constant Velocity) : If a body covers equal distance in equal intervals of time in a given direction then it is said to be moving with constant velocity. Over a small interval of time, the speed can be taken as constant. So equations of motion becomes v = u + gt, s = ut +1/2 gt, 3.A ball is thrown vertically upwards with a velocity of 20 m/s.
