it works by having the bucket tied to the rope on a pulley system that you lower done into the well and then the bucket fills up and after this you pull the rope and the bucket of water will come up full
Pulley in wells helps to pull the water because force is multiplied in movable pulley and in fixed pulley force is transfered from point to point.
To make a pulley, get a coat hanger. Cut the bottom of the hanger, and insert the open ends into an empty wooden spool. Adjust wire so spool turns easily, and then bend the ends so that the spool won't fall off. Hang rope on the spool. Attach one end of rope to a bucket or can. To use, hang the pulley and pull on the end with no bucket or can.
Wells are naturally occuring and have natural spring water in them. In most wells the makers have dug deep into the ground and struck water. The water, in turn wells up (hence the term well) and fills the deep gap. To get water out of a well, first you need to construct a bucket lowering mechanism, lower the bucket, and pull it back up. There you have it.

Pulleys helps changing the direction of the applied force. The most common example is drawing a bucket of water from a well. Without the pulley it would be laborious to pull a bucket full of water out of the well. With the pulley our applied force's direction change and we can now happily pull the water out of the well.

You could pull on a rope and use a pulley to do this, or you could wind the bucket up and down using a spindle with a leaver handle.
A bucket for the parts that you pull.

Because the centripetal reaction force of the rotating bucket exceeds the force of gravity attempting to pull the water out.
A pulley can be seen in the Gym. A pulley can be seen on the well - which is used to draw water. A pulley can sometimes be seen on the elevator, which is used to pull the car.

When you pull up the flag you pull it up by the rope. The rope has a pulley on it. So the actual poll is not a pulley but it has a pulley system on it
It could be used to pull ships onto land and to get water from a well. Archimedes invented the compound pulley in ancient Greece.
