Experiment⭐ 30 XP⚡ Spark LabNewton's First Law: Objects at Rest
Energy Transfer.
🎯 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
Newton's first law states that an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force. This is called inertia.
Key Words
- Newton
- acceleration
- velocity
Materials Needed
- weights
- tape
- ruler
- cardboard
- marbles
Safety First
- Tie back long hair before starting the experiment.
- Protect your work surface with newspaper or plastic.

Steps
Read about Energy Transfer and write down three key facts.
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.
Observe what happens and describe it in detail.
Record your observations in your science journal with measurements and descriptions.

Question 1
1 of 3What does Newton's third law state?
Where you see this in real life
You use this every time you flip a light switch, ride a bike, or kick a ball.
Stretch Challenge
Try this in real life this week.
Time how long a small ball rolls down something, then change the slope and try again.
For the dinner table
“Show me something at home that uses this kind of energy.”
