– Acceleration is the rate of change of velocity.
– Displacement is the change in position.
– Zero acceleration means no change in velocity. Constant velocity means zero acceleration.
– If velocity (v) is constant, displacement (s) is given by s = v*t. For a constant v, s increases linearly with time t.
