Questions and Answers

What is the formula for angular velocity (omega) in terms of frequency (n)?

  • $\omega = \frac{2\pi}{n}$
  • $\omega = 2\pi n$ (correct)
  • $\omega = \frac{n}{2\pi}$
  • $\omega = \frac{1}{2\pi}n$
  • What is the acceleration responsible for the change in direction of velocity in Uniform Circular Motion (UCM)?

  • Centripetal acceleration (correct)
  • Tangential acceleration
  • Radial acceleration
  • Linear acceleration
  • What is the magnitude of centripetal or radial acceleration in UCM?

  • $a = \omega^2 r$ (correct)
  • $a = -\omega^2 r$
  • $a = \frac{v^2}{r}$
  • $a = v\omega$
  • In which direction is the centripetal acceleration always directed in circular motion?
