Newton's Second Law for Rotation

Definition

Newton's Second Law for Rotation states that the net torque acting on an object is equal to the product of its moment of inertia and its angular acceleration. It relates the rotational motion of an object to the forces causing it.

Torque:

Torque is a measure of how effectively a force can cause an object to rotate and is calculated as the product of force and lever arm distance.

Moment of Inertia:

Moment of inertia quantifies an object's resistance to changes in its rotational motion, depending on both mass distribution and shape.

Angular Acceleration:

Angular acceleration measures how quickly an object's angular velocity changes over time, similar to linear acceleration in linear motion.
