Motion and Forces.
🎯 Your mission
Master the concept. Use it tomorrow.
⚡ The twist
Energy never disappears — it just hides somewhere else.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Before you start: which will move faster, and why?
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
- gravity
- friction
Steps
Read about Motion and Forces 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.”
