๐ŸงชLab Brief #45

Motion and Forces.

๐ŸŽฏ Your mission

Master the concept. Use it tomorrow.

โšก The twist

Energy never disappears โ€” it just hides somewhere else.

๐Ÿคฏ

Mind = Blown

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

๐Ÿ”ฎ

Make a hypothesis first

Before you start: which will move faster, and why?

What You'll Learn

Renewable energy sources like solar, wind, and hydroelectric power can be replenished naturally. Nonrenewable sources like fossil fuels take millions of years to form.

Key Words

  • energy
  • kinetic
  • potential

Steps

Step 1 โ€” Read

Review the background information on Motion and Forces before starting.

Step 2 โ€” Do

Build a simple motor using a battery, magnet, wire, and paper clip supports. Observe how electromagnetic forces create rotation.

Step 3 โ€” Observe

Note any unexpected results and think about why they happened.

Step 4 โ€” Record
