Gravity Assist Simulator
1. Fold 1” lip on bottom of sheet of paper.
2. Tape straw to top paper.
3. Drop ball bearing through straw and mark trajectory.
4. Place magnet near trajectory.
5. Notice how ball bearing’s trajectory is deviated.
6. Moving the magnet will create differing degrees of deviation.
