Rolling, Sliding, and Stopping.
🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Guess: where does the energy go?
What You'll Learn
A force is a push or pull that can change an object's motion, shape, or direction. Forces are measured in Newtons and can act through contact or at a distance.
Key Words
- lever
- pulley
- inclined plane
Materials Needed
- tape
- ruler
- cardboard
Safety First
- Tie back long hair before starting the experiment.
- Protect your work surface with newspaper or plastic.
- Adult supervision recommended.
Steps
Review the background information on Energy before starting.
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.
Use your senses (except taste) to describe what you notice.
Write a summary of your findings in 3-5 sentences.
Check Your Understanding
Question 1
1 of 3What is the formula for Newton's second law?
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.”
