Circular motion refers to the movement of an object along a circular path, necessitating centripetal force for direction change. It encompasses uniform (constant speed) and non-uniform (changing speed) circular motion, along with key concepts like centripetal force, angular velocity, and tangential velocity. Applications range from planetary orbits to everyday phenomena such as spinning fans and clock movement.

2. What is Circular Motion?
• Circular motion refers to the movement of an
object along a circular path. It involves
continuous change in direction, requiring a
centripetal force to maintain the motion.

3. Types of Circular Motion
• 1. Uniform Circular Motion: The object moves
with constant speed along the circular path.
• 2. Non-Uniform Circular Motion: The object's
speed changes as it moves along the circular
path.

4. Key Concepts of Circular Motion
• - Centripetal Force: The force directed towards
the center of the circle that keeps the object
in motion.
• - Centripetal Acceleration: The acceleration
directed towards the center, causing change in
direction.
• - Angular Velocity: The rate of change of
angular position.
• - Tangential Velocity: The linear speed of the
object along the circular path.

5. Centripetal Force Formula
• Formula: F = (m * v^2) / r
• Where:
• - F: Centripetal force
• - m: Mass of the object
• - v: Tangential velocity
• - r: Radius of the circular path

6. Applications of Circular Motion
• - Motion of planets and satellites in orbits.
• - Rotational dynamics in machines and
vehicles.
• - Motion in amusement park rides.
• - Understanding forces in curved road
navigation.

7. Circular Motion in Everyday Life
• - The spinning of a ceiling fan.
• - Rotation of wheels and gears.
• - Movement of the hands of a clock.
• - The orbits of celestial bodies around the Sun.
