List the forces acting on an object resting on an inclined plane with friction. For each force, describe its direction relative to the inclined plane.
Explain how the angle of inclination affects the component of gravity acting parallel to the inclined plane. How does this component influence the likelihood of the object sliding down the plane?

Quick comprehension check
“A 7 kg block rests on an inclined plane angled at 25°. The coefficient of static friction between the block and the plane is 0.4. Will the block slide down the plane? Show your calculations and explain your reasoning. (g = 9.8 m/s²) A block is placed on an inclined plane. The angle of the incline is 30°, and the coefficient of static friction between the block and the plane is 0.55. Will the block slide down the plane? Show your calculations and explain your reasoning. (g = 9.8 m/s²)”
