Vibratory motion occurs at a fixed point as an object moves back and forth. It can also be defined as an object forced to move to and fro periodically, occurring when a particle is vibrated. Oscillatory motion is related to vibratory motion.

Types of vibratory motion include forced vibratory motion and free vibratory motion. An example of free vibratory motion is when a child is on a swing and the swing is let go after a push. Two other basic forms of motion include translator motion, which is along a path or straight line, and rotary motion, which is around a central point in concentric circles.
