7 questions

1

List the forces acting on an object resting on an inclined plane with friction. For each force, briefly describe its direction.

2

Explain how the angle of the incline affects the component of gravity acting parallel to the plane (mg sin θ).

Quick comprehension check

A 2 kg block is placed on an incline of 20°. The coefficient of static friction between the block and the incline is 0.3. Will the block slide down the incline? Show your calculations and explain your reasoning. A box is on an inclined plane with an angle of 35°. The coefficient of static friction between the box and the plane is 0.6. Will the box slide down the incline? Show your calculations and explain your reasoning.
