Rotational Mechanics

Rotational mechanics is the study of how objects spin and rotate. Just as linear motion involves forces causing straight-line movement, rotational motion involves torques that cause objects to twist. Key concepts include angular velocity (how fast something spins), moment of inertia (how mass is distributed around the axis of rotation), and angular momentum (a measure of an object's rotational motion). Newton's laws apply here too: for example, a net torque leads to angular acceleration, similar to how a net force leads to linear acceleration. Understanding these principles helps explain everything from how a spinning tops behave to the dynamics of planets.
