Experiment⭐ 30 XP⚡ Spark LabNewton's First Law: Objects at Rest (Part 3)
Energy Transfer.
🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
The opposite of what you expect is often what happens.
Mind = Blown
🎢 You feel weightless on a roller coaster because you and the seat are falling at the same speed.
Make a hypothesis first
Predict: what happens if you double the force?
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
Materials Needed
- tape
- ruler
- cardboard
Safety First
- Handle glass items carefully to avoid breakage.
- Do not mix unknown chemicals together.
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.”
