NEET Physics Question - Work Energy and Power - Potential Energy & Equilibrium

Assertion (A): Frictional forces are conservative forces.

Reason (R): Potential energy can be associated with frictional forces.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Frictional forces are non-conservative forces because the work done by them depends on the path taken and energy is dissipated as heat. Potential energy can only be associated with conservative forces (e.g., gravitational, elastic).

Therefore, both assertion and reason are false.
