A pulley system is a machine that changes the direction of the force needed to do a task without changing the size or force needed. It allows you to pull downwards to lift an object upwards.
A pulley is a simple machine that changes the direction of the force needed to move an object without changing the amount of force required. By using a pulley, you can apply a downward force to lift an object upwards.
A pulley is a simple machine that changes the direction of the force required to perform a task without changing the amount of force needed. By redirecting the force, pulleys make it easier to lift or move heavy objects.
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.
A type of machine that changes the direction or amount of force needed to do work is called a simple machine. Examples include levers, pulleys, and gears. These machines help make tasks easier by altering the force needed to accomplish them.
A pulley can do that.

A machine that changes the direction or amount of force needed to do work is known as a "simple machine." Simple machines include tools like levers, pulleys, and gears that help make work easier by either amplifying or redirecting forces.
Simple
A pulley can do that.
A machine that changes only the direction of force has a mechanical advantage of 1. This is because it does not multiply the input force, but rather changes its direction to make work easier.
Machine
It changes the direction of the input force only
