Posted on. (Answer #2). Sound is a form of mechanical energy because the source of sound is vibration. Mechanical energy consists of gravitational potential energy and kinetic energy. Vibrating particles have kinetic energy which is a form of mechanical energy.osted on. (Answer #2). Sound is a form of mechanical energy because the source of sound is vibration.
