But does the kinetic energy instantly revert to potential energy at the impact zone, does it continue, or does it occur just after the point of impact and the full effect of kinetic energy actually depends upon the tackling technique of the defender?
Comparing relative mass and velocity does Iafeta Paleaaesina display a greater kinetic engery at the impact zone than say Rob Burrow?
How does friction affect the same? Does Stuart Fielden wearing a short sleeved shirt present greater friction at the impact zone than say Jamie Peacock in a long sleeved shirt?
I think he needs to be clearer in his explainations.
