Inclined Planes and Friction
Learning Objective
I can predict the motion of an object on an inclined plane by analyzing the forces acting on it, including friction, using free-body diagrams.
Practice Questions
This lesson includes 7 practice questions to reinforce learning.

1. Draw a free-body diagram for a block at rest on an inclined plane, including the force of gravity, the normal force, and the force of static friction. Label each force.
2. Explain why the normal force is not always equal to the force of gravity. Under what conditions *is* the normal force equal to the force of gravity?
3. A box is placed on an inclined plane. As the angle of the incline increases, what happens to the component of gravity acting parallel to the plane, and how does this affect the force of static friction required to keep the box from sliding?
