Re: squash ball question



I have a different take on this one.

Once again neglecting any changes in the rubber, the lower the
temperature, the lower the pressure in the ball, and correspondingly,
the larger the distortion of the ball on bouncing. The larger the
distortion, the larger the dissipation in the rubber. I agree there
should be no dissipation of energy in the gas. Thus, the lower the
temperature, the larger the dissipation in the ball on bouncing.
That is the long and short of it, more or less.

Sorry, It is past my bedtime and I couldn't resist.
