Draw a free body diagram showing all the forces acting on a block of mass *m* sitting at rest on an inclined plane with friction. Label each force.
Explain how the angle of an inclined plane affects the component of gravitational force acting parallel to the plane (mg sin θ).

Quick comprehension check
“A 25 kg box is placed on an inclined plane that makes an angle of 40° with the horizontal. The coefficient of friction between the box and the incline is 0.15. Calculate the acceleration of the box down the incline. Show all work. A 75 kg crate is on an inclined plane with an angle of 20° relative to the horizontal. The coefficient of friction between the crate and the plane is 0.3. Determine the acceleration of the crate down the incline. Show all work.”
