1. Draw a free body diagram of a block resting on an inclined plane. Label all forces acting on the block.
2. Explain in your own words why the normal force is not always equal to the force of gravity. Give an example using an inclined plane.
3. A box is placed on an inclined plane. The angle of the incline is slowly increased. Describe what happens to the force of static friction as the angle increases, and explain why.
