θ represents angular displacement, which is the change in angle undergone by an object as it rotates or revolves around a specific axis.
The rate at which an object rotates or revolves around a specific axis, measured in radians per unit of time.
A twisting force that causes angular acceleration on an object.
Rotational Inertia (Moment of Inertia): An object's resistance to changes in its rotational motion, determined by its mass distribution and shape.
