Form 11: Wheel and Axle Mechanics
In this interactive exercise, students will explore the principles of mechanics by designing and building their own wheel and axle systems, while investigating how different configurations impact speed and efficiency. Dive into hands-on experimentation to enhance your understanding of friction, force, and rotational motion!
