A surprising find looking for something else:
http://www.physics.usyd.edu.au/~cross/

Somewhat extensive notes on various small-ball sports physics - including material on collision physics and a neat vid of a falling slinky.

I've mined:
Ball bounce for comparative data for experiments involving a ball-bearing hitting a force transducer plate.
The paper has F-t graphs for several different situations appropriate to a class and useful for answering those questions about the "force of an impact".

Including a whole section on what happens when you drop heavy objects onto Silly Putty :D

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
