Potential Energy: Stored Energy (Part 3).
🎯 Your mission
Master the concept. Use it tomorrow.
⚡ The twist
The opposite of what you expect is often what happens.
Mind = Blown
🔥 A bolt of lightning is 5 times hotter than the surface of the sun.
Make a hypothesis first
Predict: what happens if you double the force?
What You'll Learn
Potential energy is stored energy based on position or condition. A ball at the top of a hill has gravitational potential energy. A stretched rubber band has elastic potential energy.
Key Words
- potential energy
- work
Steps
Study the diagram and label the parts you recognize.
Test friction: pull a weighted box across 4 surfaces (carpet, tile, sandpaper, foil). Use a spring scale to measure the force needed for each.
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 type of energy does a stretched rubber band have?
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.”
