Friction on Inclines
Grade 12•45 minutes
Learning Objective
I can predict whether an object will slide down an inclined plane based on the angle of the plane, the coefficient of friction, and the object's weight.
Practice Questions
This lesson includes 7 practice questions to reinforce learning.

1. Draw a free body diagram showing all the forces acting on a block of mass 'm' on an inclined plane with friction. Label each force.
2. Explain how the angle of the incline affects the component of gravity acting parallel to the plane (mg sin θ). How does this component influence the likelihood of the object sliding?
3. Define the coefficient of friction (μ) and explain how it relates to the magnitude of the friction force.
