Lesson⭐ 30 XP⚡ Spark LabMomentum and Collisions
Momentum and Collisions.
🎯 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
Momentum is mass times velocity. A heavy truck moving slowly can have the same momentum as a light car moving fast. Momentum is conserved in collisions.
Key Words
- work
- simple machine
Steps
Read about Forces and write down three key facts.
Test Newton's Third Law: blow up a balloon, attach it to a straw on a string, and release. Measure how far it travels with different amounts of air.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.

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.”
