A ramp is a flat surface that connects a lower level to a higher level. Ramps make it easier to move heavy objects from a low place to a high place because you don't need to use as much force as it would take to lift something straight up. The steeper the ramp, the greater the force needed to move the object up it. A wheelchair ramp is an example of a ramp that makes it easier to lift something heavy. Another name for a ramp is an inclined plane.
