Explain in your own words how the force of gravity acting on an object on an inclined plane is broken down into components. Why is this breakdown necessary when analyzing motion on an incline?
Describe the relationship between the normal force and the component of gravity perpendicular to the inclined plane. How does the angle of the incline affect the magnitude of the normal force?

Quick comprehension check
“A 5 kg box sits on an incline of 20°. The coefficient of static friction between the box and the incline is 0.35. Will the box slide down the incline? Show your calculations and explain your reasoning. A block of wood with a mass of 2 kg is placed on an inclined plane with an angle of 15°. The coefficient of static friction between the wood and the plane is 0.4. Will the block slide down the plane? Show your calculations and explain your reasoning.”
