⚙️ Gears: How They Work
Master the fundamentals of gears in this Grade 4 physics quiz! Learn how gears with interlocking teeth transfer motion and force between connected wheels, and discover how they change speed and direction of rotation. This quiz covers gear structure, function, and real-world applications aligned with the Ontario Grade 4 curriculum. **What you'll learn:** - Identify gears and describe their key features (teeth, wheels) - Explain how interlocking teeth transfer motion and force - Predict changes in speed and direction when gears connect - Apply gear concepts to everyday machines
