Question

A mechanical wave is a wave that ___ it’s energy

Answer 1

Transmits it’s energy I think. Like sound waves, that’s an example of how it can transmit its energy. It requires a medium to do so.

Answer 2

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy.
