Coefficient of rebound 1

[kilkenny]

Can anyone explain the meaning of "coefficient of rebound"? Steinberg, in "Vibration Analysis for Electronic Equipment" mentions it in the following equation:

V=C*(2gH)^.5

where
V=velocity change
C=coefficient of rebound (1.0-2.0)
g=acceleration of gravity
H= drop height

Thanks

That is an odd way of describing it, but C tells you how much rebound you get at C-=1 the velocity drops to zero at rebound, whereas at C=2 the falling item will rebound to the initial drop height.
