What is the formula for angular velocity (omega) in terms of frequency (n)?
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)?
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?
What is the magnitude of centripetal or radial acceleration in UCM?
- $a = \omega^2 r$ (correct)
- $a = -\omega^2 r$
- $a = \frac{v^2}{r}$
- $a = v\omega$
