In circular motion, If the angular velocity and angular acceleration becomes parallel, then the motion becomes:
Correct answer: B. Faster
- A. Slower
- B. Faster
- C. Constant
- D. Both 'A' and 'C'
Explanation
Option B is correct because as the body moves faster in a circular path, its angular velocity increases and it gains angular acceleration, which is in the same direction as the angular speed, resulting in them being parallel to each other as per the question's requirement. Options A, C, and D are incorrect due to the mismatch in the relationship between angular velocity and acceleration in the given scenarios.

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.
