Inclined Planes

In this video, Bill Nye the Science Guy shows a simple machine example of the inclined plane. Nye shows that the distance vertically to the second floor is the same for both the pole, ladder and ramp, the only difference is the horizontal distance. The force is smaller, therefore making it easier, for the ramp because the distance is large.
Force x Distance = Force x Distance
The work in is equal to the work out, meaning that the work for both the pole and the ramp is the same. Both have the same amount of work, the difference is the small distance in the pole resulting in the large force, making it harder to climb up. The ramp has a large distance, so the force is smaller, making it easier to walk up.
