Question

define uniform circular motion . is it accelerating motion or not?give reason.

Answer 1

UNIFORM CIRCULAR MOTION IS DEFINED AS THE MOTION IN WHICH AN OBJECT COVERS EQUAL DISTANCE IN EQUAL INTERVALS OF TIME ON A CIRCULAR PATH.
THIS TYPE OF MOTION IS ACCELERATING SINCE THE VELOCITY IS NON- UNIFORM . THIS IS BECAUSE EVEN IF THE OBJECT IS MOVING WITH CONSTANT SPEED ON THE CIRCULAR PATH, STILL IT'S DIRECTION IS CHANGING AT EVERY POINT.
