Kinematics belongs to the branch of physics called classical mechanics.

Here's why:

* Classical mechanics deals with the motion of objects and the forces that cause that motion.

* Kinematics focuses specifically on the *description* of motion, without considering the forces that cause it. This includes concepts like displacement, velocity, acceleration, and their relationships over time.

While kinematics doesn't directly deal with forces, it lays the foundation for understanding dynamics, which is the study of how forces affect motion.
