`{ \red{ \bold {\mathbb {\textit{Circular \: motion}}}}}`

MOTION OF THE BODY CIRCULAR PATH IS CALLED CIRCULAR MOTION

FEW IMP POINTS ABOUT IT :-

1. ‌A tengential is always responsible for change in speed
2. ‌If the Direction of acc and velocity is same then body's speed inc
3. ‌If they r in oppsite direction then Body's speed dec .
4. ‌If speed becomes constant then tangential acc become zero .
5. ‌By the basis of tangial acc the circular motion is divided into two types uniform circular motion and non uniform circular motion

`{ \blue {\bold{UNIFORM \: CIRCULAR}}} \\ \green{ \bold{ MOTION}}`

1. ‌when object in a circular path in a constant speed or constant circular speed is called uniform circular motion.
2. ‌In case of uniform circular motion acc tendial will be zero
3. ‌In case of uniform circular motion acc centripetal will be equal to net acc.

`{ \green{ \bold{ NON UNIFORM}}} \\ {\blue{ \bold{CIRCULAR \: MOTION}}}`

1. ‌Centripetal acc is not equal net acc
2. ‌Circular acc and tendial acc is not equal to zero .

`\pink{ \huge {\bold{EXAMPLES \ratio- }}}`

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

Answer 2

"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.
