Explain how a pulley system works to lift heavy objects. (e.g. as one end of the rope is pulled down, the object on the other end is lifted)

• The pulley system uses a combination of fixed and movable pulleys to distribute the weight of the object being lifted.

• The pulley system relies on the force of gravity to lift heavy objects

• The pulley system works by using magnets to lift heavy objects

• A pulley system operates by using a series of springs to lift heavy objects
