The statement was about when it was "falling". And its true even if you
interpret this as meaning even during collisions.

I defended it because its true.

Simple as that.

I have not obfuscated. I have simply said the statement is true, and asked
if you don't believe its true, say why.

No.

Why not quote me?

I am happy to defend anything I say.

Well, this has been discussed.

But as I keep pointing out, the forces literally do not enter the equations
for what happens after inelastic collisions (or elastic ones, for that
matter). As I have done on many previous occassions, I recommend you Google
"inelastic collisions" or go straight to
http://en.wikipedia.org/wiki/Inelastic_collision and note the complete
absence of any force term or even any terms with the units of force in any
of the discussion or solutions. The concept of "force" is as relevant to
solving the equations of motion for collisions as is the colour the floors
were painted - ie completely irrelevant. That is why the Wikipedia page (and
Physics 1 textbooks) don't even mention "force" as something that enters the
equations.

Actually, the exact word they use is "falling", but that doesn't matter; as
I said their statement is absolutely correct.

It does.

There was.

Perhaps if you provide an exact quote of something I said that you think is

Parse everything to death all you want so that you can continue your
campaign of obfuscation, but you know for certain that the context
of that statement was as a premise for the assertion that the lower
structure had no reason to fail as a result of the upper block
falling on it because it was designed to support that weight. You
know this because you responded many times to that argument.

Moreover, the statement itself, when taken as a whole, and not
parsed as you keep doing so as to obfuscate the issue, is clearly
indicating that the "N" to which they refer is a reaction to "mg"
(i.e., the weight of the upper block). Not the result of resisting
the momentum of the upper block, but of the weight "(mg)" of the
upper block.

And the proof that this is so is contained in what followed in that
report. And before you go there, what followed in that report had
been posted here very many times by your KOOK brethren, and so you
cannot claim that you didn't know the context unless you lie, which,
of course, you will. And you can keep claiming that I've never told
you what other force was at play during that collision, but that's
just another lie on your part. I've said it all along, and I'll say
it now. The force ignored by that statement was F=(d/dt)mv.

And BTW, as to your response about your other mistake? "All I [you]
did" was entirely incorrect as it pertained to the question. What
you did was analogous to someone asking you what color the sky is,
and you answering that the ocean is deep. It's a valid comment, but
it's wrong as it pertains to the question.

The question at hand was how much resistance the support structure
provided to the fall of the upper block, and your approach was to
assume zero as a premise to your answer. Notwithstanding the fact
that your approach was overly simplistic anyway, it was nonsense as
an answer to the question at hand.

There is no IF, KOOK! It's right there in the statement. And
during the collision, the force normal to the upper block (N) isn't
the mg of the falling block, it's the (d/dt)mv of the falling block.
The statement is therefore wrong, and anyone who says it's right is
also wrong. That's you, KOOK!

Yes, you're a very simplistic thinker. That's why you tried to
answer the question of whether or not there was any resistance to
the falling block by assuming there was none from the outset. LOL!

The logical conclusion of what you've said is that there are

Sure it has. We've asked, and you've avoided answering.

And there's the proof. Instead of telling us what forces you think
were acting on the block, you go on and on about how you don't know
what to do with the equations you looked up on the internet. LOL!
