Physics

The total mechanical energy will decrease.

Total Mechanical Energy (TME) is the sum of an object's kinetic energy (KE) and potential energy (PE).

When non-conservative forces, such as friction or air resistance, act on a system, they do work on the system, which results in a loss of mechanical energy. This lost energy is typically converted into thermal energy (heat) or other forms of energy like sound.
