NEET2005PhysicsWork, Power and EnergyActual
Assertion : Frictional forces are conservative forces. Reason : Potential energy can be associated with frictional forces.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion
- BIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Correct answer
D. If both assertion and reason are false.
Step-by-step solution
Frictional work is not completely recoverable. When the force of friction is the total mechanical energy is not conserved. The friction force is therefore called a nonconservative or a dissipative force.
