Form 4: Second-Class Levers
In this engaging exercise, students will explore the principles of second-class levers through hands-on activities and real-life examples, enhancing their understanding of mechanical advantages and how forces interact in everyday tools like wheelbarrows and crowbars. Let's experiment with various lever setups and calculate their effectiveness to see physics in action!
