Definition: Circular Motion refers to the movement of an object along the circumference of a circle or rotation along a circular path.
Key Concepts:
Angular Displacement: The angle through which an object moves on a circular path.
Angular Velocity: The rate at which an object changes its angular position.
Angular Acceleration: The rate of change of angular velocity.
Centripetal Force: The force that keeps an object moving in a circular path, directed towards the center of the circle.

Centripetal Acceleration: The acceleration of an object moving in a circle, directed towards the center.
Types of Circular Motion:
Uniform Circular Motion: Motion with constant speed along a circular path.
Non-Uniform Circular Motion: Motion with varying speed along a circular path.
Real-Life Examples:
Planets orbiting the sun.
A stone tied to a string and swung in a circular path.
