Question

a particle is moving in circle of radius 1m

Answer 1

Answer:

Explanation:

This motion is known as uniform circular motion , it has a centripetal acceleration of( 1m/s^2 ), towards the center of motion or the center of the circle . To find displacement and distance we must know the position or the time .for example , distance after one period is (2x3.14 x1 = 6.28 m) .and the displacement is zero and so the average velocity. the period of the motion is (6.28 sec)

Answer 2

A particle is moving in a circle of radius one metre then it is a uniform circular motion .and the cause of uniform circular motion is a centripetal force
