Kinetic Energy: Energy in Motion (Part 2).
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
Energy never disappears — it just hides somewhere else.
Mind = Blown
🎢 You feel weightless on a roller coaster because you and the seat are falling at the same speed.
Make a hypothesis first
Before you start: which will move faster, and why?
What You'll Learn
Kinetic energy is the energy of motion. A moving car, a rolling ball, and a flying bird all have kinetic energy. The faster an object moves, the more kinetic energy it has.
Key Words
- potential energy
- work
- power
Materials Needed
- cardboard
- marbles
- paper clips
- rubber bands
- blocks

Steps
Review the background information on Energy before starting.
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.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.

Question 1
1 of 3What type of energy does a moving object 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.”
