Question

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

Explanation:

Static friction acts between surfaces at rest (non - moving) to prevent motion. Option A is kinetic friction (between moving parts). Option B: Static friction is a resistive force, not a pushing force. Option C: Static friction isn't about heat dissipation. Option D matches the definition of static friction.

Answer:

D) Friction between non - moving parts.
