All of the options given are related to the process of an object changing position from one location to another. However, "motion" specifically refers to the change in position of an object over time. The study of motion and the description of its characteristics falls under the branch of physics known as kinematics. Velocity is a measure of the speed and direction of an object's motion. Mechanics, on the other hand, is the broader field of physics that includes the study of motion, forces, and energy.
