A vibrating object, such as a guitar string or vocal cords, moves back and forth rapidly to produce sound waves. The vibration creates changes in air pressure, which our ears detect as sound when they reach them.
That is referred to as oscillation, where an object or entity moves rapidly in a repetitive manner either back and forth or up and down. This motion is characterized by a regular pattern of variation.
When sound moves forwards and backwards rapidly, it is called oscillation. This back-and-forth movement is what creates sound waves.
Kinetic energy moves back and forth. This is the energy associated with the motion of an object. For example, a swinging pendulum or a vibrating guitar string demonstrate kinetic energy moving back and forth.
It is called vibrations.
