Average acceleration is the total change in velocity (magnitude and direction) over some extended period of time, divided by the duration of that period. Instantaneous acceleration is the rate and direction at which thevelocity of an object is changing at one particular moment.

Speed = Distance per unit time
symbol = v
= Distance/time
velocity = The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
symbol = V
= (v-u)/t
acceleration = a vehicle's capacity to gain speed.
symbol = a
= (v-u)/t
