How does the inclined plane do your works faster and easier? - Answers

The reason that inclined planes allow us to reduce the force necessary to move items is because the work required to do both (Work = Force x Distance) is the same. When pushing up an inclined plane, the pusher only has to counteract the component of gravity that wants to slide the object back down the plane, instead of fighting against the entire force of gravity. Using an inclined plane decreases the force necessary to accomplish the task but increases the distance required for force against the vertical component. (An angled plane shortens the distance of travel overall).
