Question

Notes on uniform circular motion and non uniform circular motion

Answer 1

Uniform circular motion...
when a body moves in circular path with constant speed is known as uniform circular motion

there are two types of accelerations in circular motion
1.centripetal acceleration
2.tangential acceleration

Centripetal acceleration is responsible for change in direction of velocity while tangential acceleration is responsible for change in magnitude of velocity

so in case of uniform circular motion there isn't change in magnitude of velocity but the direction of velocity changes at each point as the body is moving in circular path

Non-uniform circular motion...
When a body moves in circular path but its direction as well as magnitude of velocity changes at each point

in case of non uniform circular motion both types of accelerations will produce

the centripetal acceleration is always directed towards the center of the circle

hope it will help
