Scientific Curiosity

[toat in a burtle]

One of my friends in lower sixth form said that the rotation of the Earth should be affecting our travel times. I was really confused, but now I'm actually curious. Does its rotation affect how long it takes us to get to or from somewhere, depending which way we're going?

You want me to prove that gravity determines the orbits of everything in space?

Would you next ask for proof that the Sun doesn't revolve around Earth?

Prove that velocity has nothing to do with it.

I know it's a tall order (because you can't. because it isn't true) but try anyway.

Simple, velocity isn't the force that determines the orbit. It is gravity.

I have already stated that.

An object can circle around the earth at X or Y velocity and still remain in the same altitude.

But, it was your claim and the burden of proof is not on me. So if you are looking for a thesis on the subject, prove your claim first. And some random internet site relaying false information is not a valid source.

Isn't it weird when someone chucks up a simple physics question, but then refuses to include more advanced concepts. Such as how being connected to an objects gravity can, while maintain a constant speed, also effects relative speed, in regards to that object.

I mean, one you wrap your noggin around it, it is kind of world blowing... But also leaves you with some weird questions.

Better not to delve too deep into the mysteries of the universe unless you wish to end up with more questions than answers.

Saying it over again is not proof. Aerodynamic flight is also not proof because it is the lift vector that allows altitude to be maintained. This only works in atmosphere.

An object that is moving faster carries more momentum which means gravity has less of an apparent effect the the faster the object is moving, but the closer the object is, the stronger the pull of gravity. So close objects need to move faster to stay in orbit, and far objects don't need to move as fast.

It's simple enough to know that if you slow an object enough it will fall out of orbit, and if you speed it up enough it will break away from orbit and never come back.

An astronaut with zero velocity will quickly find himself on a collision course with the ground.

Meh. I like questions. Just don't care for this one very much. Being caught in a gravity plain of a massive object connects your relative speed in regards to the object, not to what the object is doing. Each level of a gravity connecting to an object, controls said object. Sol is the center of our system. The Earth rotates in relation to it's established field of influence. The moon Rotates the Earth, also in relation to the Earth's gravity. Then we fly, we establish a lesser orbit around said planet. But the key word for all of these are "Relative." You have to think of each point where an object gains control of another through mass and velocity, that that object now has a new frame of reference for it' relative velocity.

It sounds weird. But hear me out. If I send a plane East and West, both at the same speed, they are doing countless things at once. They are traveling at the Milky Way's trajectory and speed as it dictates. We are traveling along Sol's path at that speed as well, Then we are also traveling at Earths speed and trajectory. And then they are traveling at their owns speeds in regards to all of that other stuff. Both planes are traveling at the same speed and covering the same distance in relation to Earth's movement. They are still orbiting the planet at the same speed. They are simply moving apart.

We are not discussing about staying in orbit. What determines the orbit is gravity, not velocity. What you need to stay in orbit is a constant velocity. They are two entirely different things.

And an astronaut with zero velocity will not find himself on a collision course with the ground. He will only do so if caught within earth's gravity well. And even then, the moment that happens he gains velocity. So it is not 0 anymore. I know you are desperately trying to argue here, but you keep being wrong. Sorry about that.

Yes. If we were to truly take into account all the things that need to be taken into account for accuracy, to say that it becomes complicated is an understatement.

Oh FFS.

Velocity determines HOW HIGH YOUR ORBIT IS.

Also if the astronaut could in any way collied with the ISS then HE'S IN EARTH'S GRAVITY WELL

Unless now you're going to say that you're not talking about the ISS being in orbit around Earth and now you want to have it flying through deep space all of a sudden.

Stick to the damn topic and stop being an obtuse weasel.

[😼Studio Cat😼]

Actually, And Astronaut at zero velocity in regard to Earth orbit is stationary. He is neither gaining velocity to escape orbit nor losing velocity to decay into Earth's gravity well.

His velocity in relation to the Earth is ZERO.

Gravity determines the orbit. Velocity determines how fast you are travelling. Altitude determines how high your orbit is. You are attributing a unit of speed to a unit of distance, which is ridiculous.

You mentioned the ISS. I am simply theorycrafting a space station and an astronaut. Where they are is irrelevant.

No because nothing will be good enough for you.

I'm betting NASA isn't good enough for you. http://www.nasa.gov/audience/forstudents/5-8/features/nasa-knows/what-is-orbit-58.html

You're going to say it's wrong so why the ♥♥♥♥ should I bother.

It's there. Find it yourself. I'm not your teacher. Go to school.

So. Then what is your frame of velocity. Velocity is the speed of an object in a given direction in relation to an object. You said at zero velocity, an astronaut would crash to Earth. And some rambling about the I.S.S, Except the Astronauts velocity would be tied directly to the object he is tied to. Earth.

If an object were to suddenly have zero true velocity in regards to objects surrounding it, then it would simply be whisk away into the emptiness of space.

For an object to have velocity, it has to have direction. In relation to another object.
