🎯 Action and Reaction
Learn about forces that come in pairs! When one object pushes or pulls on another, the second object always pushes or pulls back. Discover action-reaction pairs through real-world Grade 2 activities like jumping, throwing, and bumping into things. **What you'll learn:** - Forces always come in pairs—action and reaction - Every push gets a push back; every pull gets a pull back - Action-reaction pairs happen in jumping, throwing, and collisions - The two forces in a pair are equal in strength but opposite in direction - Action-reaction pairs work together in everyday movement
