Watch the coin orbit!
The Gravity Well here at The Austin Children’s Museum teaches us about energy. When the coin drops lower into the well some of its gravitational potential energy is converted into kinetic energy. As the coin drops down it has higher velocity. Also, the coin goes around in smaller circles the lower it gets. So you can see how the coin completes orbits much faster near the center of the well, just like a planet would orbiting around the sun!
Make your own gravity well:
What you need:
- large piece of paper
- various balls
- paper tube
Experiment with balls or marbles of all shapes and sizes and send us your results. Do the heavier ones travel faster? What about the smaller ones?
Send us your pics of your homemade gravity wells!
