Worked practice questions

In circular motion at radius r and speed v, the centripetal acceleration is:

  1. v/r
  2. v²/r
  3. r/v
  4. mv²
Show answer and solution

Correct answer: B. v²/r

a_centripetal = v²/r — directed toward the center. Alternatively, a = ω²r where ω is angular velocity. This is the acceleration required to keep the body on its circular path.
