Gravity bends marble paths
Open to everyone until Thursday, October 1
To keep it, print it while it is open.
Gravity makes objects pull toward each other. A heavy ball can bend the paths of small marbles so they roll around it.
In the picture
- The central steel ball: a heavy mass that pulls the sheet down and attracts nearby marbles.
- The curved groove of a marble: a path bent around the heavy ball by its pull.
- The deepest part of the dip: where the pull toward the heavy ball is strongest.
Examples
- Earth travelling around the Sun.
- The Moon travelling around Earth.
Key takeaways
- Every object with mass pulls on other objects.
- A sideways-moving object can keep falling around a larger body in an orbit.
