Question

An object is moving with a uniform speed in a circle of radius r calculate the distance and displacement .1.what type of motion does the object possess

Answer 1

First of all the the object is Is in a Circular Motion...
the distance will be 2pi
the displacement will be ZERO....

Answer 2

distance can be calculated by using the measurement which the object covered and if the position of object initial and final position is same then its displacement is zero.
this type of motion is called uniform circular motion
