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

1. Define the coefficient of kinetic friction in your own words. What does a higher coefficient of friction indicate?
2. A block with a mass of 2 kg rests on an inclined plane angled at 30°. If the coefficient of kinetic friction between the block and the plane is 0.3, calculate the force of kinetic friction acting on the block. (g = 9.8 m/s²)
3. Explain why the normal force on an object on an inclined plane is *not* equal to the object's weight (mg), but rather to mg*cosθ.
