Rotation is the act of turning or spinning around a central axis. In mathematics and geometry, rotation refers to the movement of an object around a fixed point, known as the center of rotation. This movement can be clockwise or counterclockwise, and the angle of rotation determines the amount of turning that occurs. Rotation is a fundamental concept in geometry and is used to describe the orientation of objects in space.

Rotation is the motion of an object around a fixed point or axis. It is one of the three fundamental types of motion, along with translation and vibration.
Key Features of Rotation:
- Axis of Rotation: The imaginary line around which the object rotates. It can be a single point, such as a pin, or a line, such as when a wheel rolls.
- Angular Velocity: The rate at which the object rotates, measured in radians per second (rad/s), degrees per second (°/s), or revolutions per minute (RPM).
- Angular Acceleration: The rate at which the angular velocity changes, measured in radians per second squared (rad/s²).
- Moment of Inertia: The measure of an object's resistance to rotation about a given axis.
- Rotational Kinetic Energy: The energy associated with the rotation of an object, given by: Ek = (1/2)Iω², where I is the moment of inertia and ω is the angular velocity.
Types of Rotation:
- Circular Motion: When an object moves in a circular path, it is said to be in circular motion. All points on the object rotate around the center of the circle.
- Rolling Motion: When an object moves along a surface while also rotating about an axis perpendicular to the surface. Examples include a wheel rolling or a ball bouncing.
- Spinning Motion: When an object rotates about an axis that passes through it without moving from its position. Examples include a spinning top or a fan.
Examples of Rotation in Everyday Life:
- The rotation of the Earth on its axis causes day and night.
- The rotation of a fan blades creates airflow.
- The spinning of a washing machine agitates clothes.
- The rotation of a car engine converts linear motion into rotational motion.
- The rotation of a Ferris wheel provides a panoramic view.
