The negative of the work done on a system by conservative internal forces equals the change in

Options

Akinetic energy
Bpotential energy
Ctotal energy
Dmechanical energy

Correct answer

B. potential energy

Step-by-step solution

By definition, the change in potential energy of a system is equal to the negative of the work done by conservative internal forces on the system. U = -W_ c where U is the change in potential energy and W_ c is the work done by conservative internal forces.
