Question

distinguish b/n a uniform nd non uniform circular motion. for a uniform circular motion find the acceleration. if the speed is variable in circular path , give the net acceleration .

Answer 1

Difference between uniform circular motion and non uniform circular motion are as follows

1. In uniform circular motion there is no tangential acceleration, while in non-uniform circular motion there is tangential acceleration along with radial acceleration.
2. In uniform circular motion the angular momentum remains always conserved, in non-uniform circular motion it may or may not remain conserved, will not remain conserved if an external torque is responsible for the angular acceleration.
