motion

Definition

Motion is the change in position of an object over time. Objects can move in a straight line, a circular path, or any other path.

There are three main types of motion:

Translational motion: This is when an object moves in a straight line or a curve. For example, a car moving down the road is in translational motion.
Rotational motion: This is when an object rotates around an axis. For example, a spinning top is in rotational motion.
Vibration: This is when an object moves back and forth or up and down. For example, a guitar string vibrating is in vibrational motion.

Etymology

The word "motion" comes from the Latin word "motus," which means "movement" or "change." The Latin word "motus" is derived from the Proto-Indo-European root "meh₂-," which also means "movement.".

The word "motion" was first used in English in the 13th century. It was originally used to refer to the movement of objects through space, but it is now used to refer to any kind of movement, including the movement of ideas or proposals.
