A pulley makes work easier primarily by **changing the direction of the lifting force to work with gravity**. This allows a person to pull down on a rope, which in turn lifts the object up. While a pulley does not reduce the weight of the object or decrease the distance over which the force must be applied, it provides a mechanical advantage that can help in lifting heavy objects more easily.
