Inclined Plane
An inclined plane is a simple machine that is a flat, sloped surface. An inclined plane makes it easier to move a weight from a lower elevation to a higher elevation. An inclined plane allows you to exert your force over a longer distance. As a result, the input force needed is less than the output force. The input force that you use on an inclined plane is the force with which you push or pull an object. The output force is the force that you would need to lift the object without the inclined plane. The mechanical advantage of an inclined plane can be determined by dividing the length of the incline by its height. This is shown in the equation below.
If the height of the incline does not change, increasing the length of the incline will increase the mechanical advantage. The longer the incline, the less input force you need to push or pull and object.
