In terms of conservation of total enrgy, what happens to the lost kinetic energy?


Expert Answer

Step 1

The total mechanical energy of an isolated system is always conserved. The total mechanical energy may include different kinds of energy such as kinetic energy and potential energy. Even though total energy is conserved, one form of energy of a system such as kinetic energy may not be conserved.

Step 2

According to the work energy theorem, change in kinetic energy of a system is equal to the work done. If kinetic energy is lost from a system, the energy is used to do work . The work may be do...
