Dynamics Is the branch of physics developed in classical mechanics concerned with the study of forces and their effects on motion. The dynamics falls under two categories: linear and rotational. Linear dynamics pertains to objects moving in a line and involves such quantities as force, mass/inertia etc and Rotational dynamics pertains to objects that are rotating or moving in a curved path and involves such quantities as torque, moment of inertia/rotational inertia and rotational motion etc.
