<P> Moving an object up an inclined plane requires less force than lifting it straight up , at a cost of an increase in the distance moved . The mechanical advantage of an inclined plane , the factor by which the force is reduced , is equal to the ratio of the length of the sloped surface to the height it spans . Due to conservation of energy , the same amount of mechanical energy ( work ) is required to lift a given object by a given vertical distance , disregarding losses from friction , but the inclined plane allows the same work to be done with a smaller force exerted over a greater distance . </P>
