Correct answer: D). If an object's velocity is changing, it's either experiencing acceleration or deceleration
Acceleration can be defined as the rate of change of velocity of an object with respect to time. It is the result of all the forces, which are acting on the body. It can be calculated by dividing the change in velocity with the change in time.
If the velocity of an object is increasing it means the object is in motion and if it is decreasing it shows that the object is experiencing deceleration.
