Wind Energy and Turbines (Part 2).
🎯 Your mission
Learn the rule. Then catch nature using it.
⚡ The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Guess: where does the energy go?
What You'll Learn
A force is a push or pull that can change an object's motion, shape, or direction. Forces are measured in Newtons and can act through contact or at a distance.
Key Words
- attract
- repel
- motion
Steps
Look at the vocabulary words and write a definition for each in your own words.
Build an electromagnet by wrapping insulated wire around a nail and connecting it to a battery. Test how many paper clips it can pick up. Try adding more wire coils.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
