my face when the answer to the picture is pi

go to youtube, type in "khan academy _whatever you're studying_"

so for me: Khan academy algebra II

>>mfw when I'm the only one who sees he posts "both houses of congress are democratic" meaning our time is different from his
>>time takes a different turn, all the cool stuff he gets won't happen now

here's what I do in situations like these: try not to laugh at their face, (this usually happens with me), and explain to them this quote:
"Is God willing to prevent evil, but not able?
Then he is not omnipotent.
Is he able, but not willing?
Then he is malevolent.
Is he both able and willing?
Then whence cometh evil?
Is he neither able nor willing?
Then why call him God"

is /b/ raiding this board? The intelligence here seems to have dropped since I was here yesterday.

let me tell you about our physics class and our school. Our teacher is here about 2 out of 5 days a week, one of which he teaches one he tests us. The other three are "relax days" as he calls them. We're on chapter 4 in our book (of 12).

I guess I'm asking to much of /sci/ to help me

>>1966342
we haven't gone over angles or anything like that yet.

Hey /sci/ I know you guys don't much like homework problems but this is more of a test prep thread. I have a test tomorrow on Newtons 3 laws and some of his equations. Them being: F=ma and F=M(a+g)

can you give me some problems you think would appear on a test for a senior in honors physics?

thanks, it's much appreciated.

also, I did most of the practice problems in the book but I just wanna make sure I get an A on this test to bring my % up to 96.

>reading fiction
I read books about facts, not some fantasy land bullshit. You read all 7 hairy balls books? great, I read all of Schroedinger's books about physics you twat.

Reading fiction = watching TV
One is pretentious and uses words no normal person would use in their life and both get you nowhere in life and contribute nothing of meaning to society.

does the LHC give tours? That'd be so cool . . .

>>1916753
finished up elegeant universe a few days ago . . .

is string theory legit?

Teach me something cool /sci/, been depressed lately, science always cheers me up. Science channel sucks now so you're all I have.

physics preferred

>>1781467
yes i am in algebra II, learning calculus though :P

>>1781442
CHRIST my bad, what I mean is: Why does the weight of an object increase as its speed increases?

>>1781428
true there's no dumb niggaz' but they're are the pretentious white fold who have no idea what they're doing.

Also I'm 18 so suck-a my balls-a.

honors is very different from normal physics, we weren't even doing labs in the normal course, we also get to learn a bit about theoretical physics and the like.

okay I'll put it into context:

say object x has a mass of 1g and is traveling at 10mph. What will be it's weight if it's speed increases to .995(c)? Why can't an object then slow down just a bit then increase it's speed again? Wouldn't this release the weight constraint?

I GOT INTO HONORS PHYSICS Y'ALL!

I got switched into it today! I'm so happy, it's thanks, in part, to you guys too. So for me, give yourselves a pat on the back.

ITT we talk about relative velocities and why matter can never exceed the speed of light. Having a bit of trouble understanding the ideas behind Einsteins math.

mainly why is it exactly that mass ways more the faster you go?

>>1769472
is that as ever as have gone to be going and where it all begins?

>>1769457
yes i know
where as
v= .6(c)
u= .6(c)
c= lightspeed (meters

so s= .6(c)+.6c)/1+(uv/c)

is my math right?

.6(c) = 1.8x10^8?

c = 299,792,458(.6) = 179875474.8

>>1769449
ehh i worded it badly but consider the two coming towards and then passing one another

>>1769446
how do i plug data into the equation? (highshool fag here)
i want to see if both are traveling at .6 will one be faster than light relative to the other.
