Potential Energy & Equilibrium

Which one of the following forces cannot be expressed in terms of potential energy?

Show answer and solution

Answer: (a)

  1. A potential energy exists only for conservative forces.
  2. Friction is non-conservative (its work depends on path), so it has no potential energy.
  3. So the answer is (a) Frictional force.
