Friction on an Inclined Plane

1. Describe the forces acting on a block resting on an inclined plane. How does each force contribute to the block's motion?

2. Explain how the coefficient of friction affects the motion of a block on an inclined plane. What happens to the motion if the coefficient of friction increases?

3. A block with a mass of 10 kg is placed on a 30-degree incline. If the coefficient of friction between the block and the incline is 0.3, calculate the normal force acting on the block.
