GRAVITY WELL -8B40.50

- Roll a ball in the gravity well so that it moves in a circle near the top.
- Observe the ball rolling in circles as it slowly drops down into the gravity well.
- As the ball drops lower into the well it goes around the circle in a shorter time.
- When it approaches the center of the well it zips around so fast that it becomes a blur.
- Roll two balls at different positions and observe the relative velocities.
