Weve started to factor in real-world elements into our problems, and another very useful element is having an inclined ramp. Rather than a box sliding across the surface of a table, a box sliding up a ramp now has a retarding y-component as well as the x-component. Here we need to call upon what we learned in the beginning about breaking up a problem and solving for each dimension, and solving for the x- and y-components to find the total retarding force. Inclined planes are very common physics problems, so make sure you can do these frontwards, sideways, backwards, and blindfolded!
Draw a free body diagram for the object on the incline, utilizing the direction of the object’s motion (or the ramp) as one of the positive axes.
For any forces not lining up with an axis, break that force up into components parallel to an axis and draw a pseudo free-body diagram.
Utilize Newton’s 2nd Law equations along each axis direction to solve for unknown quantities.
