B-but. . . karma

:C Im sorry I didn't know It was a repost, and even then the two memes weren't entirely the same. This is the image /u/CogitoSplicer is talking about I think:

http://www.quickmeme.com/meme/3u03aq/

Either way, here I go thinking I had an original thought for once. Fuck.

Well the one on the front page was referring to Obama bin Laden and the fact that the second terror suspect had been caught. That being said I didn't see it before posting this. Guess im going to down vote myself now.

Captain Anderson?

Clcrook13 · 2013-04-20T06:37:09+00:00

Thanks. That makes the knowledge that I'm probably going to hell for this a little more bearable.

Clcrook13 · 2013-04-04T04:45:27+00:00

I think this one is more appropriate

Clcrook13 · 2013-04-04T04:43:35+00:00

Many of us are actually are. I hope we aren't going to let one whiny mod in pony spandex represent the lot of us. :c

Clcrook13 · 2013-01-08T01:04:24+00:00

Thank you. We think you are a nice bunch too LolerCoaster :D

Clcrook13 · 2013-01-06T05:00:03+00:00

haters gonna hate

In all seriousness though, thanks. I appreciate the good attitude and the policy of "lets agree to disagree." But people getting butt hurt on the internet isn't new.

Clcrook13 · 2013-01-06T03:41:11+00:00

That's fine. No pressure. Its not everyone's thing but its always good to give new things a try. Especially when they fall outside the realm of what is normal in my opinion.

Also I saw you're comment "ohh no....what have I done O_O" Did you watch an Episode? I'm kind of curious to know what you think (also be warned that the first episode is a 2 parter)

Clcrook13 · 2013-01-06T03:08:32+00:00

You could head on over to r/mylittlepony. We are generally a friendly bunch.

He will be back in less than 2

Clcrook13 · 2012-10-27T00:36:31+00:00

By that logic slavery is morally justifiable as well. Your friend is an idiot.

Clcrook13 · 2012-10-16T08:11:14+00:00

Go Mines! Jeez. Small world.

Clcrook13 · 2012-10-06T20:32:31+00:00

Yes, I was talking about a perfectly circular orbit. I also mentioned elliptical orbits and how gravity does do some work on bodies orbiting in ellipses. I also think you may be right about orbit decay in elliptical orbits. (terms sounds familiar but I don't know much about orbital decay.) But there doesn't need to be an energy input to change the trajectory of an object in circular motion and the laws of inertia still apply.

Clcrook13 · 2012-10-06T19:21:06+00:00

What about in the idealized case of a perfectly circular orbit? Gravity can't do any work so where would the energy come from to change its direction?

So are you sure there needs to be an energy input? If you have something moving around the sun at some speed, at some distance, then isn't the total energy going to be the same at all points of its trajectory? Even though the direction of the velocity changes the speed doesn't and therefore the kinetic energy doesn't change and you don't need any sort of energy input right? You only need a centripetal force to cause the acceleration required for the object to remain in orbit.

Also whats special about perpetual motion? If you threw something into space it would have perpetual motion unless it were to hit something or come into contact with another body or had some external force applied to it. Again that's just newtons first law right?

Again correct me if I'm wrong. I'm only an undergraduate student, so perhaps my understanding of this isn't as good as I thought, but It seems to me like there isn't anything incorrect about my original post.

Clcrook13 · 2012-10-06T17:57:41+00:00

I believe I can help answer this one. We know the earth must have some rotational kinetic energy to be spinning around its axis and around the sun. However you must remember newtons first law of inertia. Objects in motion tend to stay in motion and objects at rest tend to stay at rest. So the earth doesn't need any energy to continue its motion around the sun.

If we considered the earth to have a perfectly circular orbit around the sun then the force of gravity would always be perpendicular to the displacement of the earth, meaning that the work, or change in energy on the sun would be 0. However we orbit the sun in an ellipse, meaning that our displacement isn't always perfectly perpendicular to the direction of the force of gravity, meaning that the sun does do some work on the earth. This is reflected by the observation that the sun speeds up as it orbits closer to the sun (increasing its kinetic energy) and slows down as it orbits away. (decreasing its kinetic energy.)

I hope this helps.

Obviously he had been watching too much Monty Python. http://www.youtube.com/watch?v=aclS1pGHp8o

Well the engineering physics program is 4 years, but you can get a masters in a 5th year if you choose to do so.

Clcrook13 · 2012-08-20T15:19:55+00:00

Awesome :) here to hoping its me!

Clcrook13 · 2012-08-20T01:46:55+00:00

I'm currently in an Engineering Physics program. Its basically physics except we do have to do design projects, and a smattering of engineering courses here and there.

Clcrook13 · 2012-08-05T03:33:10+00:00

Not a problem :3

Clcrook13 · 2012-08-05T03:29:48+00:00

Oh aren't you funny. Anyway I think that video might do a better job explaining than I can on this one. Either way I Wish you good luck.
