🎿 Friction & Surfaces
Explore friction as a force that opposes motion and is created when surfaces slide past each other. Discover how different surface textures—from rough sandpaper to smooth ice—affect how fast objects move and how much effort it takes to slide them. Through real-world examples and experimental thinking, you'll understand friction in activities like skating, sliding, and braking. **What you'll learn:** - Friction is a force that opposes motion between sliding surfaces - Rough surfaces create more friction than smooth surfaces - Surface texture directly affects movement speed and how easily objects slide - Real-world examples of friction in everyday activities like skating and braking
