Define the coefficient of friction and explain how it affects the force of friction between two surfaces.
Explain how the weight of an object on an inclined plane is resolved into components parallel and perpendicular to the plane. Draw a diagram to support your explanation.

Quick comprehension check
“A 20 kg box is placed on an inclined plane with an angle of 20°. The coefficient of friction between the box and the plane is 0.3. Will the box slide down the plane? Show your calculations and use a diagram to support your answer. A 100 kg crate is placed on an inclined plane with an angle of 45°. The coefficient of friction between the crate and the plane is 0.8. Will the crate slide down the plane? Show your calculations and use a diagram to support your answer.”
