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.

Mechanical Energy Facts. The mechanical energy of an object is the sum of its energy in motion and its stored motion. This means it is the sum of its kinetic and potential energy. Although the kinetic and potential energy of an object can change, its mechanical energy remains constant.he mechanical energy of an object is associated with the objects' position and motion. In a few cases, some mechanical energy is converted to heat resulting in less mechanical energy. Some machines or devices can convert heat into mechanical energy.
