Explain in your own words how the force of gravity acting on an object on an inclined plane is resolved into components. Why is this necessary for analyzing the motion of the object?
Draw a free body diagram for a box being pushed *up* an inclined plane at a constant speed. Include the force applied to the box, the force of gravity, the normal force, and the force of kinetic friction.

Quick comprehension check
“A 2 kg block is placed on an inclined plane with an angle of 25°. The coefficient of kinetic friction between the block and the plane is 0.3. Determine the acceleration of the block down the incline. Show all work. A box with a mass of 5 kg is sliding down an inclined plane at a constant speed. The angle of the incline is 20°. Calculate the coefficient of kinetic friction between the box and the plane. Show all work.”
