Energy loss in bouncing. 600fps slow motion.

http://www.youtube.com/watch?v=M41nypMjLUs explains?
The rubber of the blue ball to the right absorbs very little energy.
Its low damping and high-elastic properties should NOT be found in road vehicle tires or in vehicle crush zones protecting occupants from injuries due to great g-forces.
The change of velocity in the blue rebouncing ball is almost twice as great as in the red ball with high-damping rubber, which transmits most of the kinetic energy to heat and increased temperature within the rubber material.

The 35 seconds duration of this clip correspond to about 1.5 seconds in real-time.

The same two bouncing balls demonstrated by Halvard Nilsson in my clip May 29 2009 have here been captured with Casio Ex-F1 in 600 frames per second.
For explanation in Swedish, see that clip:

To reduce skidding, tires are made from high-hysteresis rubber with viscous damping properties - such as in the red ball to the left.

The clip only shows a difference in elasticity between two kinds of rubber compound.

WOAH! :O

That's interesting! Did that red ball seriously get pulled in some way from the bounce of the blue ball?

need be more slow and more zoom
