Which of the following is a non-conservative force?
Correct answer: A. Frictional force
- A. Frictional force
- B. Effort + distance
- C. Effort-distance
- D. Effort +distance
Explanation
Frictional force is a non-conservative force.due to its energy-dissipating nature and the path-dependent work it entails. This contrasts with conservative forces like gravity and spring force, which store energy and have potential energy associated with them.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
