Bouncy Ball Collision
Download Clip (221 Kb)
This
is a slow motion video of a small rubber bouncy ball colliding with
a wall at very high velocity. It is interesting to see how much the
rubber compresses and rebounds after the collision. Another observation
worth noting is that the speed at which the ball leaves the wall is
almost the same as the speed at which it approaches it. This can be
explained by the elasticity of the bouncy ball--the very thing which
causes the ball to bounce. The framerate used for this video was 2000
frames/sec, while the shutter speed was 10X, or 1/20000th of a second.
