Question
The period of rotation (T) and the frequency (f) are inversely related. Which expression correctly gives the angular velocity (ω)?
Correct Answer
Option A is the correct answer.
Detailed Explanation
The lecture provides the formulas ω = 2π/T and ω = 2πf rad/s, demonstrating the relationship between angular velocity, period, and frequency.
Hint
In one period T, the object completes one revolution, which is an angular displacement of 2π radians. How is average angular velocity calculated from this?
