Pulley
Pulley explained in an easy to understand way:
Imagine trying to lift a heavy box onto a high shelf by yourself. Just like asking a friend to help you lift the box makes the task easier, a pulley uses a wheel and rope to distribute the weight, making it easier to lift heavy objects. In this analogy, the friend represents the wheel's role in the pulley, while the rope acts as your combined effort, working together to make lifting manageable.
Practice Version
