MCQ
The negative of the work done by the conservative internal forces on a system equals the change in:
  • A
    T​​​​​otal energy.
  • B
    Kinetic energy.
  • Potential energy.
  • D
    None of these.

Answer

Correct option: C.
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. $\text{W}=-\triangle\text{ P.E.}$
