Total energy of a system is always conserved, no matter what internal and external forces on the body are present.
Options
True
False

Solution
This statement is False.
Explanation:
Even though internal forces are in equilibrium and do not perform work on a body, it is the external forces that possess the capability to do work. Consequently, external forces can alter the energy state of a system.
