Find Three Ramps in the Wild

A ramp is an inclined plane that allows you to move an object to a greater height with less force than is needed to simply lift the object. A ramp can also be used to ease an object from a higher to a lower height.

Although it has no moving parts, a ramp is still considered a simple machine. It is called an inclined plane since it is a flat surface at an angle. 

Resistance from friction can affect the mechanical advantage of a ramp. Since the friction of sliding an object up a ramp can increase the force required, rollers or wheels are usually used to reduce the friction and increase the force mechanical advantage.

Summary:

A ramp is an inclined plane that allows you to move a heavy object to some height with less force than needed to lift the object. A ramp can also be used to ease an object to a lower height.
