Rotational kinematics refers to the study of motion in a rotating system, specifically the relationships between angular displacement, angular velocity, and angular acceleration.
Imagine you are sitting on a spinning chair. Rotational kinematics is like studying how your body moves as you spin around - how far you rotate (angular displacement), how fast you spin (angular velocity), and how quickly your spinning speed changes (angular acceleration).
Angular Displacement: Angular displacement is the measure of the angle through which an object rotates or revolves. It represents the change in position or orientation of an object in a rotating system.
Angular Velocity: Angular velocity is the rate at which an object rotates or revolves around a fixed axis. It measures how quickly an object's angular position changes over time.
Angular Acceleration: Angular acceleration is the rate at which an object's angular velocity changes over time. It represents how quickly an object's rotational speed increases or decreases.
