Sound - a form of mechanical energy produced by vibrating objects that is transmitted by pressure waves through a medium - needs a medium with particles to travel/propagate - cannot travel in a vacuum (medium with no particles) Mechanical Energy - has to be transmitted - propagated from one point to another - need a medium (can't propagate without a medium) Cycle - used to describe any changes in particle motion (particle displacement, density, or molecules, pressur...
