In physics, the branch that studies motion without considering its causes is known as:

1. The stem asks for the name of the branch of physics that studies motion only, without asking why the motion happens. 2. OpenStax Physics opens this topic by stating: "kinematics—the study of motion without considering its causes." 3. Dynamics, by contrast, studies motion together with the forces that cause it -- the opposite of what the question describes. 4. So the correct term is kinematics. _Source: OpenStax Physics Ch 2 "Motion in One Dimension", p.56 §2.1 Relative Motion, Distance, and Displacement_
