Kinetic Energy: Energy in Motion (Part 3).
🎯 Your mission
Understand the idea. Then look for it everywhere.
⚡ The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
🔥 A bolt of lightning is 5 times hotter than the surface of the sun.
Make a hypothesis first
Guess: where does the energy go?
What You'll Learn
Kinetic energy is the energy of motion. A moving car, a rolling ball, and a flying bird all have kinetic energy. The faster an object moves, the more kinetic energy it has.
Key Words
- velocity
- force
Steps
Review the background information on Energy before starting.
Build a simple circuit using a battery, wire, and light bulb. Then add a switch and test what happens when you open and close it.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
