Forces and Motion.
๐ฏ Your mission
Predict it first. Then prove yourself right (or wrong).
โก The twist
Energy never disappears โ it just hides somewhere else.
Mind = Blown
โก Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Before you start: which will move faster, and why?
What You'll Learn
Electromagnets are temporary magnets created by running electricity through a coiled wire. They can be turned on and off and are used in motors, speakers, and MRI machines.
