Friction on Inclines

1. Explain in your own words how the angle of an inclined plane and the coefficient of friction affect whether an object will slide down the plane.

2. Draw a free body diagram for a block resting on an inclined plane. Label all forces acting on the block, including the force of gravity and its components.

3. A block is on an inclined plane. The angle of the incline is 25°, and the coefficient of kinetic friction between the block and the plane is 0.3. Calculate the force of gravity parallel and the force of kinetic friction acting on the block (assume the mass of the block is 2 kg).
