In Part 1 of “The Physics of Rebounding for Superspeed” we took an in depth look at the physics behind the force production necessary to change the direction of our hands and quickly create effective weapons. In case you have forgotten or missed Part 1, the take home message of all the fancy physics equations is:

The greater the change in directional speed of an object and the shorter the time frame in which the change of speed happens the greater the observed force must be.”
