Reply #53: Then where is the opposite motion? [View All]

[HamdenRice]

This query has nothing to do with the merits of the conspiracy theory. It's has to do with the usual application of Newton's Third Law -- which is usually illustrated with the example of rocket fuel being forced downwar and pushing the rocket upward, or the recoil of a rifle back against the shoulder from a bullet ejected forward, or stepping off a row boat that has not been tied up, or jumping off a skate board. You go forward and you push the skateboard or rowboat backwards.

Here, the bullet entered from the front toward the back and pushed Kennedy's head from front to back. That is not opposite motion, but the bullet's force acting on Kennedy's head. This was a demonstration of Newton's First and Second Laws, not of his Third Law.
