The time rate of change of velocity is called:
Correct answer: B. Acceleration
- A. Force
- B. Acceleration
- C. Power
- D. Energy
Explanation
Acceleration is defined as the rate of change of velocity with respect to time. Acceleration is a vector quantity, so it includes both magnitude and direction.

About Acceleration
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
