Final answer:
Inclined planes reduce the force needed to move objects upward by spreading the work over a longer distance, providing a mechanical advantage.
Explanation:
Inclined planes are simple machines that reduce the force needed to move objects upward. One advantage of an inclined plane is that it allows us to raise heavy objects with less force by spreading the work out over a longer distance. For example, pushing a cart up a ramp requires less force than lifting it straight up vertically. Mechanical advantage is gained by using inclined planes, making tasks easier.
