Define the term "coefficient of friction" and explain how it affects the force of friction between two surfaces.
Draw a free body diagram of a box sitting at rest on an inclined plane with friction. Label all forces acting on the box.

Quick comprehension check
“A 10 kg box is placed on an inclined plane that makes an angle of 45° with the horizontal. The coefficient of friction between the box and the plane is 0.1. Calculate the acceleration of the box down the incline. Show all work. (Use g = 9.8 m/s²) A 25 kg block is on an inclined plane with an angle of 20° relative to the horizontal. If the coefficient of friction is 0.3, what is the acceleration of the block down the incline? Show all work. (Use g = 9.8 m/s²)”
