Explanation: It takes more force to start motion (overcome static friction) than to maintain motion (overcome kinetic friction).
Free-body diagram of a block on an incline: weight (mg) resolves into mg sinθ along the slope and mg cosθ into the slope, balanced by the normal force N and friction f.
Concept context
Newton's three laws, friction, circular motion, and free body diagrams.
