Which statement correctly distinguishes conservative and non-conservative forces?
AConservative forces always decrease kinetic energy, while non-conservative forces always increase it
BConservative forces do path-dependent work, while non-conservative forces do path-independent work
CWork done by conservative forces can be associated with potential energy, while non-conservative forces like friction dissipate energy
DOnly non-conservative forces can act on moving bodies
Answer & Solution
Correct answer: C. Work done by conservative forces can be associated with potential energy, while non-conservative forces like friction dissipate energy
Conservative forces, such as gravity and spring force, allow a potential energy function to be defined. Non-conservative forces like friction convert mechanical energy into other forms such as heat, so mechanical energy is not conserved in their presence.
