If angular velocity increases, _ also increases
Correct answer: B. Frequency
- A. Time period
- B. Frequency
- C. Vibration
- D. None of these
Explanation
Option B is correct since there exists a direct relationship between angular velocity and frequency and it is given by the following formula: angular velocity is equal to the product of the frequency and the constant 2pi. The constant 2pi comes from the fact that one revolution per second is equivalent to 2pi radians per second.

About Angular Velocity
Angular velocity describes how quickly angular displacement changes with time, with ω = Δθ/Δt and units of radians per second. Questions relate angular and linear motion through v = rω, use the direction given by the right hand rule, and distinguish angular velocity from angular acceleration and ordinary frequency.
