The inclined plane is the simplest of simple machines because to make it work, nothing moves. You move! Another name for an inclined plane is a ramp. It can be as simple as the driveway leading to your school or as sophisticated as the staircase in the Empire State Building. A ramp works by helping you lift things more easily up to a higher level. It can be really difficult to carry a box of stuff up a ladder. But carrying that same box up a staircase is an easier job, and carrying it up a smooth ramp is even easier.
