Uniform Circular Motion : When an object moves in a circular path with uniform speed, its motion is called uniform circular motion.
Example of uniform circular motion :
(i) Motion of the moon around the earth
(ii) Motion of the Earth around the Sun.
(iii) A satellite in a circular orbit around the earth
(iv) A cyclist on a circular track
Total Distance Covered in circular path : 2 π r
Speed of athlete in circular path : 2 π r / t
Factors due to which Changing in the velocity :
(i) Change in magnitude
(ii) Change in direction
Uniform circular motion is the motion due to change in direction of object on circular path at its each point.
