friction and terminal velocity of a parachutist vs a car

[raaaid]

well besides people here are not indulging theyre just laughing at me

whay i say:

if dynamic friction is not a function of velocity is wrong because a block falling in a ramp will reach a terminal velocity

what can i do if 99% of people study for the printed paper

the only righteous person in this thread its been outlaw

We all do, don't we? Perhaps even you, dear Raaaid. Who knows, maybe you're just desperately trying to get people's attention. And if you were, I still wouldn't understand why you'd do such a thing in this forum in particular.
Still, there are many ways to try to interpret one's behaviour.

if i ever employ anybody for anything ill make sure to discard anyone with university studies

"Every ‘complete’ course in basic physics treats Coulomb’s famous inverse square law of electrostatic force. Few courses, however, associate his name with the law of sliding friction, also treated. Perhaps influenced by the work of Leonardo DaVinci, Coulomb provided in 1779 a treatment of sliding friction that has stood the test of time.

His law is expressed in terms of two constant coefficients, one being of kinetic type, the other static, with the latter being larger than the former. Surprising to most, the magnitude of the force of friction between two surfaces is to first order independent of both speed and the area of contact—depending only on the normal force N between the surfaces."

ALL SCIENCE IS PROMOTED BY PETROCHEMICAL COMPANIES TO CONFUSE INVLEIGE AND OBFUSCATE, THE MORE YOU STUDY THE MORE STUPID YOU BECOME

edit:

ill have to point it to you dont i:

it produces the same friction 1 square cm than 1 square m if the weight its the same, that is the normal force

if people believes this bs probably theres a guy working for the government thinking hey what news will we make up today, funny, terrorific, peismistic,optimistic....

Wow seriously but hurt aren't you raaaid, how many times did you fail to get a degree?

[raaaid]

i have one degree in english literature and im 3 subjects away from getting one ine engineering

still im responsible enough as to never applied those knowledge

curiously the higher the qualification the more people believe in darwin

blind faith

edit:

i want to make a game with subsonic mind altering sound

certain frecuencies make you happy, others make you scarred

do you think i can study this in college?

where in medicine college? the number one population control tool of the state which proposed put rat poison in water so not to have cavities?

I mean, do you really like making a fool out of yourself? And don't say that you're a genius or that other people became famous because they questioned the reality as we know it: Albert Einstein was a genius because he had a thorough understanding of physics, not just because he was creative.

Albert Einstein was genius because his IQ exceed 141. He had a thorough understanding of physics because he wanted to. His creativity was a natural talent.

To the rest of your blather, I say so what?

So far I've yet to see Raaaid cause you any harm, Stern. I on the other hand find him amusing. Perhaps if you spent less time knowing everything and more time laughing at yourself, your pitiful existence might be less dark.

Let me give you a clue: When you see a thread by Raaaid, don't open it. You'll have much less stress, and so will the rest of us.

You'll need to be investigating harmonics, not frequencies per se

[raaaid]

you see guys accept it this system is nightmare like, is not like we live in a perfect wrold but we live in an extrem dystopyan one where we are given rat poison in water and 99.9% believes it heals cavity yet they still have them

but the refusal of people to see this makes the rebel look bad to his eyes

such an imperfect world is just perfect for a rebel as me

As I pointed out earlier, all good and/or real text books will note the limitations and assumptions of idealized rolling and sliding friction. So only stupid people will "believe" that contact area has zero effect on the friction force. The same could be said about people who believe that intelligent people are the aforementioned believers.

[raaaid]

yes but then why am i forced to study that friction is independent of surface and velocity if its false

whats the point of studying a false thing except for detecting it though im sure that is not the point

its really frustrating having to study things you dont share, i often feel like studying religion instead of scinece

realize that coulombs law on friction though false is studied at college level world wide
