The feet off the ground is just a result of the hitting action as the racket is pulled through the shot from what I understand, so the uper body bends forward and the lower body is thus moved upwards, combined with the original force that went upwards in the racket swinging up?
Bungalo Bill: It is not only an upward effort going to the ball but also a push from the toes to assist in the upward effort.
LOL, figures, you have nothing. Already showed my evidence Einstein.
Already have Einstein. the serve motion is not a pure jump. The server rolls onto the toes and the toes add lift-off or spring. It is painfully obvious that the toes, calves, thighs, hips, stomach, shoulders, arms, etc...are all part of the kinetic chain in a good pwerful serve.
The Toes do not produce any force, you stated they did.
The balls of the foot mearly transfer the energy of the rest of the body form the kenetic chain, that is all, the balls of the foot do not produce any force either
What don't you get?
