A particle executing one dimensional motion finally comes to rest what will be angle between acceleration and displacement during motion?
Correct answer: D. Π
- A. 0
- B. Π/4
- C. Π/2
- D. Π
Explanation
a = v/tθ = cos-1Using dot product s . a = - s . a (Concept of parallel and anti parallel)θ = cos-1θ = cos-1 (s . a = - 1)Hence answer is 180 or Π

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.
