Friction on Inclines
Learning Objective
I can predict whether an object will slide down an inclined plane based on the forces of gravity and friction.

1. Explain in your own words how the force of gravity acting on an object on an inclined plane is broken down into components. Why is this breakdown necessary when analyzing motion on an incline?
2. Draw a free body diagram for a block of wood resting on an inclined plane. Label all forces acting on the block, including the force of gravity and its components, the normal force, and the force of static friction.
3. A book is placed on an inclined plane. The angle of the incline is slowly increased. Describe what happens to the forces acting on the book (gravity, normal force, friction) as the angle increases, and explain how these changes affect the book's likelihood of sliding.
