Define Kinematics.

Kinematics is the branch of classical mechanics that describes the motion of points, objects, and groups of objects without considering the causes of their motion (e.g., forces). It focuses on quantities like position, velocity, and acceleration.

Dynamics is the branch of classical mechanics that studies the motion of objects and the forces that cause these motions. It relates the motion of a body to the forces acting on it, often using Newton's laws of motion.
