What is the difference between rotational inertia and moment of inertia, and how do they relate to each other in the context of physics?

Rotational inertia and moment of inertia are terms used interchangeably in physics to describe an object's resistance to changes in its rotational motion. Rotational inertia specifically refers to an object's resistance to changes in its rotational speed, while moment of inertia refers to an object's resistance to changes in its rotational motion due to its mass distribution. In essence, moment of inertia is a more specific term that quantifies rotational inertia. Both concepts are crucial in understanding how objects move and rotate in the context of physics.
