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 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 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 gearshift is a lever, which is a simple machine that helps change the direction or amount of force needed to move an object. In a car, the gearshift is used to select different gears, which in turn changes the speed and torque of the vehicle.

A mechanical advantage device, such as a lever or pulley, changes the direction or amount of effort needed to do work. These devices allow us to apply a smaller force over a longer distance to accomplish a greater amount of work.
It changes the direction of the input force only
