The area enclosed by a static hysteresis curve is less than
that of the corresponding dynamic curve for the same compression.
This is particularly evident for the superball, where
the energy loss is almost negligible during a static compression
and expansion. The effect is less pronounced for a baseball
since the static and dynamic hysteresis losses are both
relatively large. The superball tested did not bounce particularly
well, a result that could possibly be attributed to microscopic
cracks in the ball
