The magnitude of the angular velocity is given by:

Correct answer: B. ω= θ/t

  • A. ω = r θ
  • B. ω= θ/t
  • C. ω=θ2/t
  • D. ω=r2/θ

Explanation

The correct formula for angular velocity is ω = θ/t, where ω represents angular velocity, θ is the angle, and t is time. This formula defines how quickly an object is rotating around a fixed point in two dimensions. The other options do not accurately represent the concept of angular velocity and should be ruled out.

About Force and Motion

Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
