Galileo and Inertia
The video at the right shows what happened after I released the skater. I found that when the skater is released at the line labeled number 6 on the left-hand side of the track, he will roll back up to the line labeled number 6 on the right-hand side of the track. Note: This only happens in situations in which friction isn't present. In the real world there is friction, and so this experiment wouldn't work quite as well. |
