Question

which of the following describes kinetic friction? a) friction between moving parts. b) a pushing force. c) heat that must be dissipated quickly. d) friction between non - moving parts.

Explanation:

Kinetic friction is the friction that occurs between two surfaces in relative motion (moving parts). Option B is incorrect as friction is a resistive force, not a pushing force. Option C describes a consequence of friction (heat generation) rather than defining kinetic friction. Option D describes static friction (between non - moving parts). So the correct option is A.

Answer:

A) Friction between moving parts.
