Pulleys are really useful for lifting heavy things. Here’s a simple explanation of how they work:

• Mechanical Advantage: Pulleys help you lift heavier items without using too much strength. For example, with just one pulley, you might only need to use half the effort!

• Changing Direction of Force: Instead of pulling something straight up, you can pull it down. This is much easier.

Overall, pulleys make lifting easier and more effective!
