Question

what is acceleration?​

Answer 1

Explanation:

Acceleration: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity.

An object is accelerating if it is changing its velocity.

For example, if a car turns a corner at constant speed, it is accelerating because its direction is changing. The quicker you turn, the greater the acceleration. So there is an acceleration when velocity changes either in magnitude (an increase or decrease in speed) or in direction, or both.
