Rotational dynamics is the study of forces and motions about an axis of rotation.

Explanation:

Rotational dynamics is the study of forces and motions about an axis of rotation.

Formulas such as Kinematic Equations and Newton's laws can be expressed in rotating coordinate frames such as:

Newton's 2nd Law F_"net" = m x a translates into Torque = I x alpha Where I is Moment of Inertia (the rotational analogous term to mass)
and alpha is angular acceleration
