Define Acceleration. ​

Answer 1

$\huge\bold{AnSwEr♡}$

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

It is a measure of the change in the velocity of an object per unit time. Acceleration can be caused either by change in direction of motion or change in speed or both.
