JEE Main Physics question

**Statement 1:** Frictional forces are non-conservative forces. **Statement 2:** Potential energy cannot be associated with frictional forces.

(A)Statement 1 is true, Statement 2 is true; Statement 2 is a correct explanation for Statement 1Correct
(B)Statement 1 is true, Statement 2 is true; Statement 2 is not a correct explanation for Statement 1
(C)Statement 1 is true, Statement 2 is false
(D)Statement 1 is false, Statement 2 is true

Answer: (A)

Solution

A force is conservative only if the work it does is path-independent, which allows a potential-energy function to be defined for it. Friction's work depends on the path length
