Question

The negative of the work done by a conservative internal force of a system equals the change in its

• A. Total energy
• B. Kinetic energy
• C. Potential energy
• D. None of these

Answer 1

The correct option is C Potential energy

The work done by a conservative force equals the NEGATIVE of the change in the potential energy associated with that force.

If the potential energy associated with a force increases, this increase must be exactly balanced by changes in other forms of energy.

Answer (C) Potential energy
