Explain in your own words how the force of gravity acting on an object on an inclined plane is resolved into components parallel and perpendicular to the plane. Why is this necessary for analyzing the motion?
Draw a free body diagram for a box sliding down an inclined plane with friction. Label all the forces acting on the box.

Quick comprehension check
“A 2.0 kg block is placed on an inclined plane with an angle of 20°. The coefficient of kinetic friction between the block and the plane is 0.30. Calculate the acceleration of the block down the incline. Show your work. A wooden crate slides down an inclined ramp set at an angle of 35°. The coefficient of kinetic friction between the crate and the ramp is 0.15. Calculate the acceleration of the crate down the ramp. Show your work.”
