Step 1

Mechanical energy is the sum of kinetic and potential energy of an object.

Step 2

When two surfaces are rubbed, due to friction, the kinetic energy will get converted to thermal energy. Thus a result the kinetic energy will decrease.

Step 3

In case of friction between internal parts of an isolated system, the kinetic energy will get converted to thermal energy, reducing the kinetic energ...
