kinematics
Motion without forces
Kinematics is the branch of physics that describes motion—position, velocity, acceleration—without considering the forces that cause it.
A kinematics problem might ask how far a ball travels before hitting the ground, treating gravity's effect mathematically without asking why gravity exists.
The related field dynamics adds forces back in.
