A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.

How does a fixed pulley make work easier?
A fixed pulley does not make the force applied easier, it changes the direction of this force. For example, instead of bending over and lifting and object, a fixed pulley lets you lift it by pulling down on a rope.
How does a pulley decrease work?
No, a pulley redistributes the work making it easier but at the end of the pull it will be the same amount of work.
Ma of a pulley?

Does a pulley make work easier by changing the direction of force?
Yes. It can also decrease the amount of work needed in exchange for a long distance.
How does the pulley make work easier?
You don"t have to pull the full weight. They reduce the force needed to move an object.
