Explanation:
Detailed explanation-1: -The acceleration of an object is simply defined as the rate of change of the object’s velocity. It can be zero, positive, or negative. The negative acceleration is known as deceleration or retardation. Thus, from this discussion, the rate at which an object’s velocity changes with time is called its acceleration.
Detailed explanation-2: -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.
