Which simple machine allows a force to be applied over a greater distance?

The correct answer is that all of the mentioned simple machines—lever, pulley, and inclined plane—can allow a force to be applied over a greater distance, but they do so in different ways.

A lever enables you to lift a load by applying a force at a greater distance from the fulcrum, which allows you to move it more efficiently compared to lifting the load directly. This means that even if a smaller force is applied, it can result in a larger movement of the load.

A pulley, particularly a system with multiple pulleys (also known as a block and tackle), can change the direction of the force applied and reduce the amount of force needed to lift an object by spreading the applied force over a longer distance. As the rope goes through the pulley, you can pull down on one side to lift the load upwards, working over a greater distance.

An inclined plane allows for the application of force over a longer distance by spreading the effort required to lift an object over a slope. Instead of lifting a weight vertically, which requires a large force, the inclined plane lets you apply a smaller force over a longer distance to raise the object, making it easier to move heavy items up to a height.

In summary, each of these simple
