Per NCERT §5.8 (Points 8), is there an associated POTENTIAL ENERGY for FRICTION?
AYes, V_friction = μ N x linearly
BOnly for static friction case
CNo, friction is non-conservative
DYes, V = (1/2) μ N x² parabolic
Answer & Solution
Correct answer: C. No, friction is non-conservative
NCERT §5.8 Points 8: friction is non-conservative (path-dependent W, closed-loop W ≠ 0). No PE function exists.
