What should have happened was after letting go, Ironman should have continued along the same path per Newton's 1st Law as the missile and slammed right into the alien ship.

1st) It's a superhero movie

2nd) Physics: Ironman was NOT in Orbit around the Earth. Therefore he still had a roughly 1 G pull back towards the center of the Earth. Once he lost power, (why did he lose power? That's the real question), gravity pulled him back through. We know Earth was affecting the other side of the portal since light from NY was streaming through. No reason to think Earth gravity wasn't either.

My physics question is: Can Thor fly? Or does he throw the hammer and goes wherever it go? How does he steer? Just wondering.

The hammer is supposed to take him around.

as to op. What should have happened is all the air of Earth being sucked into the portal a la MegaMaid :biggrin:

He can hover without the hammer as long as I believe it's nearby / in the same dimension but to fly around he uses the hammer although the spinning is just to get him off the ground.

At least in the movie it is as in other shows / comics he needs to use it like a helicopter to hover and in others he can fly without it.

In Norse mythology he rides around by a goat-propelled chariot.

Thor has two servants, Þjálfi and Röskva, rides in a cart or chariot pulled by two goats, Tanngrisnir and Tanngnjóstr (that he eats and resurrects)

At least that makes perfect sense :colbert:

Was the portal leading back to a large mass still open? You think that had no immediate influence on him? :p

It seems that in the Marvel movies, Iron man is "kept in check" by making him extremely power strapped. I suppose it makes for suspense when he, the only normal human who has a more fighting ability that a bow/arrow or gun, has such a high amount of vulnerability. Considering however, that the Suit used a brand new reactor, he really needs to put in a larger power source to keep up with his massive energy usage.

Before he does that redirection thing, Jarvis mentions that Iron man is running out of power.

LOL. Physics 101 kid. Velocity is directional.

Ok let's simplify this with real life examples. For the space shuttle to reach orbit it must reach 17,500mph. That velocity must be tangential to the curvature of the Earth. The shuttles trajectory has it go mostly up for the first few minutes to clear the densest part of the atmosphere and then it kicks over for the remainder of the powered flight.

If the shuttle went straight up as soon as it ran out of fuel it would fall straight back to Earth.

Issac Newton agrees with me:

that's because in that suit the power source is that glowing thing in his chest. it has a limited power output. also if it goes out he dies..not good.

latter suits have there own source of power. personally i like the hulk buster suit..

I know. In the first movie he states the first chest piece can produce 3GJ/s. which is a fancy way for saying 3 GigaWatts peak power generation. He also says it can run something big for 15 minutes. This gives a total energy content of 750MWH.

That's huge and that was just the prototype. So where is all the power going.

The Mk 7 suit very clearly has its own power source, or otherwise it couldn't remotely deploy.

Also, he was clearly alive after his suit shut down from lack of power. After the first movie, I'm pretty sure he learned not to attach his life force to his suit power.

His technology all seems extremely power intensive. His repulsion tech seems like some sort of plasma based technology or some massive particle acceleration based technology which must suck energy down, and he is using it constantly to fly. Also, he was spamming his lasers, which clearly take some absurd about of power considering they seem to rip through armor plating like paper.

Couldn't he just get a cardiac pacemaker?

No, if the shuttle went straight up, it would escape Earth and fly out into space.

If you drop a bullet at the same time you fired a bullet, which one hits the ground first?

When you're wrong, you can't mitigate how wrong you are by going off the deep end and just posting retarded stuff.

It just makes you look stupider.

Its only retarded to you because you don't understand the concept of lift.

Do planes fall to earth? That portal was only a little above the sky scrapers, and he didn't make it that much farther after he went through the portal. There was no reason he shouldn't have fallen back to earth. He was very close to earth, the only reason he was in space was the portal he wasn't very far away from earth.

Okay. How does a plane fly? Don't give me bullshit about the bernoulli effect, thats not right.

Do you, unlike the entire aero industry, have a single clean understanding of what happens in an airflow to cause lift and have it clean enough to describe different situations that the airfoil will still produce lift even though classical definitions do not?

Because your explanation will revolutionize the entire aero industry.

Sorry, I didn't know.

Hate to quote myself but I feel I have to here...

Has anyone else noticed just how well endowed Iron Man is? I was admiring his liberal use of packing tape when I spotted what looks to be an eel in his trowserpants.
