If GFR is over 90, the kidneys are healthy and functioning normally. A kidney score of 60-89 means the person should be monitored, and if GFR scores falls to less than 60 for a three-month period, that is an indicator of chronic kidney disease.
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.

The definition of mechanical energy is power that an object gets from its position and motion. An example of mechanical energy is the power of a football flying through the air. An example of mechanical energy is a wrecking ball that is swung backwards away from a building. As the ball is swung backwards using mechanical energy, potential energy is stored. When the ball is swung forwards to wreck the building, this is kinetic energy.
