The acceleration is a _.
Correct answer: A. Vector quantity
- A. Vector quantity
- B. Scalar quantity
- C. Dimensionless quantity
- D. None of these
Explanation
Correct option is A.Acceleration is a vector quantity. This means that you include direction while describing acceleration. Slowing down means that you are decreasing your velocity, which means there is a negative change in velocity and therefore a negative acceleration.

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.
