Friction on Inclines

1. Define the force of kinetic friction and explain how it affects the motion of an object on an inclined plane.

2. Draw a free body diagram of a block on an inclined plane, including the force of gravity, the normal force, and the force of kinetic friction. Resolve the force of gravity into its components parallel and perpendicular to the plane.

3. A block is placed on an inclined plane with an angle θ. Write equations for the sum of the forces in both the parallel and perpendicular directions to the plane, in terms of the normal force (Fₙ), the force of gravity (Fₙ), the coefficient of kinetic friction (μₖ), the mass (m), and the angle θ.
