A block of mass m is released from rest at the top of an incline that makes an angle αwith the horizontal. The coefficient of kinetic friction between the block and incline is μk. The top of the incline is a vertical distance h above the bottom of the incline. Derive an expression for the work Wf done on the block by friction as it travels from the top of the incline to the bottom. When αis decreased, does the magnitude of Wf increase or decrease? | Numerade

Coefficient of friction is independent of the mass The coefficient of friction (µ) is independent of an object's mass, depending only on the materials and roughness of the surfaces in contact. But the actual force of friction does increase with mass because mass determines the normal force (weight), which friction opposes. So, while a heavier block experiences more friction, the ratio (the coefficient) stays the same, meaning it takes proportionally more force to move it, but the sliding angle o
