⚙️ Simple Machines: Pulleys
Discover how pulleys work as simple machines! This quiz explores how pulleys use wheels and ropes to change the direction of force, making it easier to lift heavy objects. You'll learn about real-world examples like flagpoles and window blinds, and understand how compound pulleys multiply our strength. **What you'll learn:** - What a pulley is and how it works - How pulleys change the direction of force - Real-world pulley examples (flagpoles, blinds, cranes) - How compound pulleys help lift heavier objects - Why pulleys are useful in everyday life
