More High-Speed Camera Fun

My last post ended with a slow-motion video of falling rolls of paper towels. Here’s a few other videos we’ve taken with the high speed camera:

Ball Bounce Challenge
Students had to predict the drop height necessary in order for the ball to bounce back up to the height of the hoop. Each group was given a different ball. They could take any measurements they wanted with the ball — but the height of the hoop was not disclosed yet. When measurements were complete, the balls were sequestered and the hoop was put in place. Groups then performed more measurements and calculations. Upon determining the drop height, each group was given back their ball and had one chance to make a successful drop:

Reaction Time
Are you quick enough to catch the dollar bill without anticipating?

Falling Meterstick
A classic demonstration. Why do some of the dice stay on the meterstick and some do not? Can you predict how far out along the meterstick the dice will remain in contact with the stick?

Other collections of high-speed video clips

And one more video nicely illustrating Newton’s 1st Law:

Have you been using high-speed videos in the classroom? How?
