Detailed explanation-1: -Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).
Detailed explanation-2: -The rate of change of velocity is known as Acceleration.
Detailed explanation-3: -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.
Detailed explanation-4: -Answer: The rate of change in the velocity of an object per unit time is referred as acceleration and the kind of motion is known as accelerated motion.
