Rotational Dynamics
- The measure of an object's resistance to changes in its rotation speed is referred to as its rotational inertia or moment of inertia.
- Torque represents the rotational force that causes changes in the rotational motion of an object.
- The rotational analog of linear momentum is angular momentum, which is a measure of an object's tendency to maintain its rotational motion.
