Did you prove this? Try this....
Take a hammer to your fender. The fender is a fixed object. Well it will
need to be "fixed" after this test :)
Now take the same hammer and hit a golf ball with the same force.
Ot make it a fender not sitting on the ground. I bet the mark isn't as bad.
Now take 2 of the same hammers (not chinese made) and snack them
together. They are gonna bounce off each other.
Take 2 fenders and smack them together, minor dents on each, now take
one fender in your hands and smack the fender on your car. I bet your
car's fender has a bigger dent.
It's gonna bounce off your fender too but it's gonna leave a mark.
Not that I want any more used rusty parts, but I bet there is a bounce
off factor in the head on where there is only 1/2 the bounce factor in
the immovable object.
Once you smash all these fenders, let us know if there is indeed a
bounce factor. I ain't no engineer so I don't give a sheet.
Example, in my line of work if I take a board (movable) and smash it
into another board alreaddy nailed up,(immovable) the smasher will most
likely snap off where the smashee will most likely look the same.
If I take those same 2 boards and smash them together, I made "clap"
boards and get a loud noise and still have 2 good boards.
then again, I could be wrong, I have been in the past.
