PHY 101 Circular Motion Objective Question

Question

The linear velocity (v) of a particle in circular motion is related to its angular velocity (ω) and the radius (r) by which expression?
Options
A v = r / ω
B v = ω / r
C v = ω²r
D v = ωr
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

The lecture explicitly states that linear velocity can be expressed as a function of angular velocity by the expression v = ωR.

Hint

Consider the units. Angular velocity is in rad/s, radius is in meters. What operation yields m/s?
