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?
Draw a free body diagram for a block of wood resting on an inclined plane. Label all forces acting on the block, including the force of gravity and its components, the normal force, and the force of static friction.

Quick comprehension check
“A 2 kg box rests on an inclined plane angled at 25°. The coefficient of static friction between the box and the plane is 0.3. Will the box slide down the plane? Show your calculations and explain your reasoning. A block of wood with a mass of 5 kg is placed on an inclined plane with an angle of 15°. The coefficient of static friction between the wood and the plane is 0.5. Will the block slide down the plane? Show your calculations and explain your reasoning.”
