the calculus of the serve and the squash shot

[carl reisig]

As I look at the speeds of the serve and the forehands recently, I see a significant difference. I haven't seen measures of the squash shot, but there was a commentator reference this last week to a really hard running forehand that was not a squash shot. (implication: squash shots are faster)

Question: is there an explanation based on the calculus for the higher speed of the serve as opposed to the ground stroke???

Carl,

Vic Braden quoted Dr Brody:

a speed of serve = a fudge factor X a speed a head of a racket


for a speed of a head of racket just below 100 miles per hour ( observed)
and a fudge factor 1.5 we would get a speed of serve around 150 miles
per hour

I am certain it has to do with the fact the groundstrokes are hit against a ball with a significant incoming velocity, but the serve is not.

i would also think that since a serve is hit "flatter" than a ground stroke (except for second serves) more energy is going into speed and less into spin. john does your spin analysis of strokes bear this out?
