Simple Electricity.

๐ŸŽฏ Your mission

Learn the rule. Then catch nature using it.

Speed isn't the same as force. Don't mix them up.

๐Ÿคฏ

Mind = Blown

โšก Static electricity is the same physics as lightning, just smaller.

Make a hypothesis first

Guess: where does the energy go?

What You'll Learn

Magnets have north and south poles. Opposite poles attract and like poles repel. The magnetic field is strongest at the poles and gets weaker with distance.

Key Words

  • energy
  • kinetic

Steps

Step 1 โ€” Read

Read about Simple Electricity and write down three key facts.

Step 2 โ€” Do
