PHYSICS HELP ITT

[ArtVandelay]

ok i have a test tommorow and i definitley slept all week because i have no idea what to do and then i forgot my text book at school so i cant even try to study.

it's on vectors. theres alot of graphing vector lines and then like making triangles and then doing sine, cosine, or tangent to find something.

literally i have no idea what to do or what im looking for, so just anyone explain anything about vectors in physics; equations, tips, anything.. help.

[Desssert]

we just finished vectors, keep up bro
we're on projectiles now

[BmphP]

rape the teacher and demand she give you an A

[Clark]

cross products?
dot products?
good shit man

[Frobes]

Take the cosign of my dick in your butt then find the slope of the path that my cum follows. This question is worth ten points.

[Frobes]

Also don't forget to show your work.

[Clark]

tip to tail, tip to tail

[Ureshii]

draw funny pictures instead

[Tweek]

do you mean victor

[Zebbs]

no he means erector

[ArtVandelay]

ok i fully understand vector components now.

now i need to learn adding vectors and i think ill be good

I'm a Physics tutor, and literally just got done tutoring some people who are taking a test tomorrow too. You aren't in PA are you?

With vectors, there is a specific method you'll want to follow to solve problems. You'll probably be given one vector, a second vector, and have to find the vector sum or difference between them.

First, go here (http://www.ac.wwu.edu/~vawter/PhysicsNet/Topics/Vectors/VectorAdditionSteps.html) and read the part titled Adding the Components Method. Then, if that doesn't make sense, come back here and ask me to explain.

you'll proly want to right this down for each problem:
Ax =
Bx =
Cx = Ax + Bx =
Ay =
By =
Cy = Ay + By =

then apply the x- and y-direction values to find C (http://www.ac.wwu.edu/~vawter/PhysicsNet/Topics/Vectors/Gifs/VectorAddition12.gif) (<--clicky) as well as the value for the angle of C in that link. C is the magnitude of your resultant vector and angle C is the angle above the positive X axis typically.

[Iceshade]

Also I know the world's easiest way to do cross products if you ever need that information too

[Raxo]

wtf you're not supposed to be helpful

[ArtVandelay]

yes i do live in PA?

god damn it you aren't supposed to help him

[Desssert]

and i bet they meet up irl and start going out

[Raxo]

then they start surfing the forums together handing out physics advice on each others accounts

[ArtVandelay]

im on the edge of my seat wondering if this person lives near me

[ArtVandelay]

ANSWER ME DAMMIT

[Zebbs]

WE'LL NEVER KNOW :wail:

[azunder]

don't listen to iceshade, i've been told he's a fgt

[Iceshade]

I'm from Johnstown, but I'm in Latrobe atm, where are you from?

I kind of realized it's common for people to have any kind of test on a Friday but that's awesome you're in PA

also sorry godammit the new Office was on

also also I'm the only person who ever helps people in Spame I've done it before

[Iceshade]

Man I hope it doesn't turn out that you're someone I know and don't like

[Zebbs]

in b4 OMG ME 2!

[Iceshade]

I'm studyin' for an Optics test and a Complex Variables test I have tomorrow so I'll check back here when I gets a chance, proly round midnight. If you have any other questions let me know

[BadAnkle]

don't bother studying or, for that matter, sleeping

instead, play this game (http://fantasticcontraption.com/index.php) all night and you'll ace that fuckin' test

[ArtVandelay]

i live in philly, kinda far.

[BadAnkle]

i live in philly, kinda far.

what part? because the west side is the blessed side

[Desssert]

were you...born and raised there

[Desssert]

oho

[ArtVandelay]

north east

also this is shagg, im sure weve talked about philly before, just have a new account

[Gilligan]

Vectors are easy as shit. You're just dumb. :science:

[ArtVandelay]

its not hard, i just fell asleep the whole time and missed it

[Iceshade]

Yeah that's a ways

[Stealth Prawn]

really all you need is a²+b²=c² and then you need to know basic trig to find the angles for your vectors.

speaking of which, are you in grade 11 physics? because in between my sleeping through physics class, i heard a few things that sound remarkably like vectors

[Stealth Prawn]

also i somehow have a 98% despite sleeping through every class. im even beating an asian. wtf is that shit

[Tweek]

oh my god maths is so gay

[Gilligan]

I fell asleep every day in physics honors and AP. My teacher let me though, because I had the highest grade. I also had the lowest overall GPA in AP Physics. Other classes had homework worth like credit and stuff.

[BmphP]

omg gilligan thats soooo interesting!

[Zebbs]

the only maths i know is math = (gay x gay)
