Gravity on an Inclined Plane

1. Describe the role of gravity when an object is placed on an inclined plane. How does it affect the object's motion?

2. In a free body diagram of an object on an incline, what are the two components of gravitational force acting on the object? Explain how you determine these components.

3. If a box is sliding down an incline at an angle of 30°, calculate the gravitational force acting down the incline if the mass of the box is 10 kg. Use the formula F = mg sin(θ).
