Circular Motion

Question 1

Define angular velocity ω and its formula.

Answer 1

Angular velocity is the rate of change of angular displacement of a body.
ω = 2π/T = 2πf

Question 2

Define centripetal force.

Answer 2

Centripetal Force Fc is any force which allows a body to undergo circular motion, and is the product of centripetal acceleration and the mass of an object.
