Respuesta :
Heat is often called the "graveyard of kinetic energy". Heat due to friction. Due to friction, kinetic energy is converted to heat and not potential energy; thus, the kinetic energy is "lost" since heat cannot easily be converted back into kinetic energy.
The energy that has been known as the graveyard of the kinetic energy has been the heat due to friction.
The kinetic energy has been defined as the energy possessed by the moving object. The energy has been created by the motion of the object.
Graveyard of Kinetic energy
The kinetic energy has been interconverted to the potential energy when the object has been at rest.
When there has been friction in the motion of the object, the kinetic energy has been converted to the heat. The heat has been difficult to convert back to the kinetic energy.
Thus, the energy that has been converted due to friction has been the graveyard of the kinetic energy.
