📚 Topic Summary
Balance is when something stays upright and doesn't fall over. To keep things balanced, we need to understand a few key concepts. The center of gravity is the point where the weight of an object is evenly distributed. The base of support is the area on which an object rests. When the center of gravity is above the base of support, the object is stable. If the center of gravity moves outside the base of support, the object will topple over. Understanding these parts will help you label what helps things balance!

✍️ Part B: Fill in the Blanks
Fill in the missing words in the following paragraph:
To maintain __________, the __________ of __________ must be above the __________ of __________. If the center of gravity moves __________ the base of support, the object will __________ over.
🤔 Part C: Critical Thinking
Explain how a tightrope walker uses a long pole to maintain balance. What part does the pole play, and how does it help the walker avoid falling?
