Define the term "coefficient of friction" and explain how it affects the force of friction between two surfaces.
Explain why the normal force on an object on an inclined plane is not always equal to the object's weight (mg). Under what conditions *is* it equal to the object's weight?

Quick comprehension check
“A 10 kg box is placed on a 25° incline. The coefficient of friction between the box and the incline is 0.15. Calculate the acceleration of the box down the incline. A 20 kg block is on a 30° inclined plane. The coefficient of friction is 0.3. Determine the acceleration of the block. ”
