Experiment⭐ 30 XP⚡ Spark LabKinetic Energy: Energy in Motion (Part 2)
Forces and Motion.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ 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
- force
- energy
Materials Needed
- rubber bands
- blocks
- spring scale
Safety First
- Do not taste any materials.
- Wear safety goggles when mixing liquids.
Steps
Review the background information on Forces and Motion 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.

Question 1
1 of 3What type of energy does a moving object have?
Where you see this in real life
This is why airplanes can fly and why rockets reach space.
Stretch Challenge
Try this in real life this week.
This week, find one thing in your house that turns one kind of energy into another.
For the dinner table
“Show me something at home that uses this kind of energy.”
