Stress Ball Collision
Download Clip (270 Kb)
Here
is a clip of a foam stress reliever colliding with a wall at high
velocity. Since foam is not very elastic, the ball does not bounce
very much at all. This is quite visible in the video, as the speed
of the ball leaving the wall is significantly less than the speed
of the incoming ball. Foam is, however, very flexible, so the ball
almost entirely compresses against the wall. The framerate used was
2000 frames/sec, and the shutter speed was 10x, or 1/20000th of a
second.
