Or what if it was a paper plate and a honda ? In the RAIN... :angry-tappingfoot:

Well I still think the protons collided with the graphite and there was a 3.5TeV collision of some sort cuz the entire block DID absorb the whole collision.

On a macro scale, kaaapow ! and all the 3.5TeV was, in some way, absorbed by the graphite block..

so there. A 3.5TeV collision did occur...

heheheh... Bad Chris :violence-stickwhack:

Yesthey did occurr, but not enough of the energy was deposited in the small space required to make it interesting.
Not the energies of the collisions matter at the end, but the concentration of energy in a small spce and that is just not impressively high for 3.5TeV protons hitting stationary carbonatoms.

Well...........

Something still hit something...

So, what sq area counts as a collision then ?

hehehe... i am just not giving up...

This still all seems wrong.. BUT I suppose I will give up my question for now.. I may revisit it tho..

has nothing to do with sq area rther how much enrgy is converted in a certain time and space from motion to any other form (most interisting here converted to (mass(particles))) and in the dump most of the energy stays just motion during the first collission in hedoncollission most is converted.

If you jump from third floor to an empty container, your potential energy is transferred to kinetic energy (during flight) and then to thermal energy (on impact). Plus you get hut badly because your collision energy is great.

If you jump from third floor to a container full of plastic foam, the transfer of your potential energy to kinetic energy and subsequently to thermal energy is the same, only the transfer to thermal energy takes place on longer track - but exactly the same amount of energy is transferred. Another difference is that in second case you don't get hurt.

Good picture kasuha. :clap:
Mine was way too theoretical. :crazy:

hmmmm........

that was good :happy-jumpyellow:

BUT...

ummm...... but something im sure..... Ummm....

well you still hit foam... I guess it depends on how you define a collision...

You still collide with the foam...

So there... :text-bump:

Hey Xymox,

you are right as long you regart hitting foam or metal with the same speed as the same you can also already call hitting the dump 3.5TeV-collissions, only the consequences are different than for the 3.5TeV-collisisons the physicists are looking for.
But just for the books you are right. But also for all other officialrecords there is e defined set of rules how the record has to be achived you also cannot beat the record in drinking beer while you are using beer with no alcohol, evenso it is still beer.

Perhaps this will help.
Yes, the dump will have involved 3.5TeV of energy. A 3.5TeV collision is one where the energy involved is 3.5TeV and the total momentum is zero (or very close to zero).
As the dump into the graphite has non-zero momentum, it isn't a 3.5TeV collision in the particle physics sense.

Well..... Now here is the real explanation...

THIS makes sense to me now...

So even if a beer is on a paper plate on a toyota going 3.5TeV, if it aint got no Alcohol, it aint beer. :obscene-drinkingdrunk:

This must be the first time alcohol has helped to solve a problem. :occasion-santa:

Just nit-picking: if 3.5TeV refers to the kinetic energy of the whole car, then it's moving awfully slow. If it refers to the kinetic energy of every individual particle that constitutes the car, however, steering will be challenging. Even without drinking alcohol, I mean.

Absolutely it refers to every particle of the beer and car..

At those speeds tho is steering even possible ? I mean it would require a lot of beer to get me into a car going at 3.5TeV, so I don't think I could steer.. So the drinking is a important aspect here..

I suppose your right,,, that much mass going at that speed might cause some guidance issues that would not be trivial..

WAIT....

Exactly how fast is 3.5TeV ? Thats not a velocity !!?!.. Hmmm...... I need a calculator.. And another beer... On a paper plate..

I think you have to be wary here. It is well known that the laws of physics change under the influence of alcohol.

3.5TeV is 5.6E-7 Joules.

As E = 1/2mv^2, m being mass and v being velocity:
v = sqrt(2*E*m)

Assuming m is 2000kg for a car:
v = sqrt(5.6E-7 * 2000 * 2)

Which comes out as 2.4E-5 m/s, or 5.3E-5 mph.

I'd happily get in a car doing that, if I didn't feel like going anywhere :P

WHAT !?!?!

Wait a minute....

I am again confuzed...

But beer is good... Home brew cask conditioned triple IPA...
