>>>No, momentum is mass * velocity: the reason why a fist hitting a face does more damage to the face than vice versa - the fist, even though lighter than the face, because of its speed has a great momentum. The stationary face, although heavier than the fist, has no momentum.

>>Huh? So if the fist was stationary and the head hit the fist at the same speed then the fist would suffer the most damage <g>

>Not so funny aamof. Yes I guess the fist would come off worse, maybe broken finger bones. How about a head-butt? Both heads about the same mass but only the stationary one feels the pain, although action and reaction are equal and opposite.
That's because the head-butter is usually a drunken yob, feeling no pain ! <s>

Though a good deal is too strange to be believed, nothing is too strange to have happened.
- Thomas Hardy
Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.
-- T. S. Eliot
Democracy is two wolves and a sheep voting on what to have for lunch.
Liberty is a well-armed sheep contesting the vote.
- Ben Franklin
Pardon him, Theodotus. He is a barbarian, and thinks that the customs of his tribe and island are the laws of nature.
