What is the SI unit of acceleration is ___________?
Correct answer: B. meter per second square
- A. Meter per secound
- B. meter per second square
- C. Both
- D. All
Explanation
Acceleration is change in velocity per unit time, so its SI unit is metre per second squared, written m/s². Meter per second is the unit of velocity, so option a is the likely mistaken choice.

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.
