Question

what is acceleration??​

Answer 1

Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both. ... Any of these would be considered an acceleration since they change velocity.

Answer 2

The rate of change of velocity is known as Acceleration.
