Answer :
"Circular motion" is motion in a circular path.
-- Any point on the tire of a bicycle or a car that is moving.
-- Any point on the hour, minute, or seconds-hand of an 'analog' clock.
-- The ball in the roulette wheel before it comes to a stop.
-- Any point on the rim of the Wheel of Fortune before it stops.
-- Any point on any propeller of a windmill, when the wind is blowing.

MOTION OF THE BODY CIRCULAR PATH IS CALLED CIRCULAR MOTION
FEW IMP POINTS ABOUT IT :-
- A tengential is always responsible for change in speed
- If the Direction of acc and velocity is same then body's speed inc
- If they r in oppsite direction then Body's speed dec .
- If speed becomes constant then tangential acc become zero .
- By the basis of tangial acc the circular motion is divided into two types uniform circular motion and non uniform circular motion
[tex]{ \blue {\bold{UNIFORM \: CIRCULAR}}} \\ \green{ \bold{ MOTION}}[/tex]
- when object in a circular path in a constant speed or constant circular speed is called uniform circular motion.
- In case of uniform circular motion acc tendial will be zero
- In case of uniform circular motion acc centripetal will be equal to net acc.
[tex] { \green{ \bold{ NON UNIFORM}}} \\ {\blue{ \bold{CIRCULAR \: MOTION}}}[/tex]
- Centripetal acc is not equal net acc
- Circular acc and tendial acc is not equal to zero .

- Earth revolving around the sun is an example of uniform circular motion
- Spinning top rotation on its own axis is example of non uniform circular motion
- Rotating/ moving blades of fan etc
- a rotating stone lied to a rope
