A single pulley is one of the "simple machines" in physics, and makes work seem easier by redirecting the action required to work along with gravity. For example, you can lift something by by pulling down on a rope.Multiple pulleys make work even easier, but you need to do more of it: running a rope through six pulleys will make the load seem 1/6 as heavy, but you'll have to pull the rope six times as far.A handy guide to the simple machines is here.
A pulley helps us work by lifting large load that we could not do by ourselves.
