A pulley system is a simple machine that changes the ratio of force to distance by allowing you to lift heavy loads with less effort. By using multiple pulleys and ropes, you can increase the distance you need to pull while decreasing the amount of force required.
A lever does not increase the distance over which a force is applied. It only changes the direction or magnitude of the applied force.

A machine that changes the direction or amount of force needed to do work is called a simple machine, which includes tools like levers, pulleys, and ramps. Simple machines allow us to make tasks easier by redistributing the force we apply over a larger distance or in a different direction.
When a simple machine helps reduce force, the distance the object moves increases. This is known as a trade-off between force and distance in mechanical systems. By applying less force over a longer distance, simple machines make it easier to perform work.
If the mechanical advantage of a simple machine is increased, the distance the input force must be applied decreases in relation to the output force. This means that you can exert less input force over a longer distance to achieve a greater output force over a shorter distance.

Levers, inclined planes, and compound pulleys all do that.

The product of force times the distance the force was directed in, is called "work".The relationship between distance and force is that, when using a simple machine, to move an object it requires less force to move an object a farther distance when using a simple machine than moving an object without a simple machine.The relationship between distance and force is that, when using a simple machine, to move an object it requires less force to move an object a farther distance when using a simple machine than moving an object without a simple machine.Addition: "Using a Force (y-axis) over Distance (x-axis), the Work done can be estimated by calculating the area under the graphed line." -Arian.
When a simple machine helps reduce force, the distance the object moves increases. This is known as a trade-off between force and distance in mechanical systems. By applying less force over a longer distance, simple machines make it easier to perform work.
If the mechanical advantage of a simple machine is increased, the distance the input force must be applied decreases in relation to the output force. This means that you can exert less input force over a longer distance to achieve a greater output force over a shorter distance.
That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.
If a simple machine provides an increased output force, then the output distance will decrease. This is due to the principle of work conservation, where input work equals output work. As the force increases, the distance through which the force acts decreases proportionally to maintain the balance.
A pulley is a simple machine that changes the direction of force. It consists of a grooved wheel and a rope or cable that runs along the groove, allowing you to pull downwards to lift an object upwards.
You multiple a force time the distance over which the force is applied.
