CBSE · Class 11 · Physics · Work, Energy and PowerWhich of the following is a non-conservative force?
Gravitational force, electrostatic force, and spring force are conservative forces because work done by them along a closed path is zero and depends only on initial and final positions. Frictional force is a non-conservative force because work done against friction depends on the path and energy is dissipated as heat.
