Question
The negative of the work done by the conservative internal forces on a system equals the change in:
  1. T​​​​​otal energy.
  2. Kinetic energy.
  3. Potential energy.
  4. None of these.
✓

Answer

  1. Potential energy.
Explanation:
The negative of the work done by the conservative internal forces on a system is equal to the changes in potential energy.
i.e. $\text{W}=-\triangle\text{ P.E.}$
