Angular velocity is also called as
Correct answer: B. Rotational velocity
- A. Instantaneous velocity
- B. Rotational velocity
- C. Tangential velocity
- D. Linear velocity
Explanation
B. Angular velocity is the rotational analog of velocity. The velocity that keeps a body within a circle during circular motion is known as angular velocity. It is directed inwards.A. The velocity of a body at any instant of time that approaches zero is known as instantaneous velocity.C. The velocity of a body in circular motion that pulls it away from the circle is known as tangential velocity. Its formula is; Vt = wr. Where omega 'w' is the angular velocity and 'r' is the radius of the circle.D. The velocity of a body in linear or one dimensional motion is known as linear velocity

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.
