Inclined planes enable objects to be lifted more efficiently by allowing the application of force over a greater distance. When using an inclined plane, the force needed to lift an object is spread out along a longer path, compared to lifting the object straight up. This means that while the force needed is reduced, the distance you must move the object along the inclined plane increases proportionately.

For instance, if you want to lift a heavy object vertically, you would need to apply a large amount of force for a short distance. However, with an inclined plane, you can exert a smaller force over a longer distance, which makes it easier to lift the object to the desired height without needing as much force at any given moment. This principle is rooted in the concept of mechanical advantage, where the trade-off between force and distance allows for more efficient lifting.

In this context, other choices do not accurately describe how inclined planes work. While it might seem that increasing the required force could be a possibility, inclined planes actually reduce the force needed to lift an object. The mention of reducing the distance needed to lift is misleading since the distance is actually increased along the plane, even though the height is achieved effectively. Applying force horizontally is not applicable since the intention is to lift
