Question

define uniform circular motion. show that linear speed of performing circular motion is the product of radius of circle and angular speed of particle.

Answer 1

Uniform circular motion speed is constant but direction changes, velocity changes so there is acceleration called centripetal acceleration.

Answer 2

A BODY ROTATING IN A CIRCULAR PATH WITH A UNIFORM MOTION IS CALLED A UNIFORM CIRCULAR SPEED . BUT HERE THE ACCELERATION IS PRESENT BECAUSE THE BODY IS CHANGING ITS PATH AT EVERY POINT WHICH IS EQUAL TO (V SQUARE/RADIUS).
