The Wheel and Axle.
๐ฏ Your mission
Play with the model. Break it. Understand it.
โก The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
โก 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
- motion
- balanced
- gravity
Steps
Study the diagram and label the parts you recognize.
Build a simple motor using a battery, magnet, wire, and paper clip supports. Observe how electromagnetic forces create rotation.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
Check Your Understanding
