# Forces on inclined planes

7 videos
4A: If you've ever moved from one town to another, you are likely familiar with inclined planes. When you push up that 50 pound box into the long flatbed truck , there are several forces at play: the weight of the box, the frictional force between the box and the ramp, and the force of your push. We will explain how these forces interact so next time the move won't be so back-breaking.
