Kinetic Energy: Energy in Motion.
🎯 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
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
- velocity
- force
- Newton
Materials Needed
- marbles
- paper clips
- rubber bands
- blocks
- spring scale
Safety First
- Protect your work surface with newspaper or plastic.
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
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.”
