Push and Pull Forces (Part 2).
๐ฏ Your mission
Run the experiment. Find out what really happens.
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.
