Q:

# How does an inclined plane work?

A:

An inclined plane works by reducing the amount of force needed to lift an object from a lower point to a higher one. The inclined plane is normally a flat surface that extends from the lowest point up to the highest, which allows things to be moved up and down the incline easier than lifting it straight up or down.

The amount of force needed to move an object up an inclined plane is determined by the length of the plane between the two points. The longer the plane, the less force is needed to move, but it will take longer to get from point a to point b. A shorter plane will require more force, but less time from point to point.

According to PBS, Galileo's inclined plane was an experiment performed to test the effects of gravity on falling objects. Galileo's inclined plane experiment eventually proved that in the absence of outside forces, gravity causes all objects to fall at an increasing rate.

The ramp, wedge and screw are simple machines belonging to the inclined plane family. Inclined planes makes it easier to move an object. Lifting an object vertically requires a great amount of force. Using a ramp requires less force, but also requires the object to be moved a greater distance.

A hydraulic lift works by using an incompressible liquid to multiply the effects of the force applied to lift something very large or heavy. A larger surface area requires a smaller amount of force to do the same amount of work.
