What are conservative forces characterized by?

• A. Work done is path-dependent
• B. Work done does not restore energy
• C. Work done is independent of the path taken
• D. Work done is always negative

Answer: (C)

Conservative forces are characterized by having work done that is independent of the path taken between two points. This means that when an object moves under the influence of a conservative force, such as gravity or spring force, the total work done when moving from point A to point B will be the same, regardless of the specific path the object takes. Another key aspect of conservative forces is that they can be associated with a potential energy function, meaning that the work done by these forces can be completely recovered as mechanical energy. In contrast, non-conservative forces, like friction, would depend on the path due to their dissipation of energy, such as converting mechanical energy into thermal energy, which is not recoverable in the same way. Thus, the correct characterization of conservative forces emphasizes their property of path-independence in the work done, reinforcing their fundamental role in the conservation of energy.
