Friction quiz for Grade 2 with answers

📚 Quick Study Guide

• 🖐️ Friction is a force that opposes motion when two surfaces rub against each other.
• 🚗 Friction can help us (like when car tires grip the road) or slow us down (like when pushing a heavy box).
• 🧊 Smooth surfaces have less friction than rough surfaces.
• 🔥 Friction creates heat. Rub your hands together quickly – they get warm!
• ⚙️ Lubricants, like oil, can reduce friction between moving parts.
