re: Astronauts are travelling at 17,500 mph (5mi/sec) when they do space walks outside the ISS

There will always be unanswered questions. The people that demand an answer then stand behind one they choose to believe in without proof are nothing more than drones.
Perfect example is the COVID response and those that followed it. These are the same people applying gravitational reactions to space.
So I know the answer? Nope
But I won't listen to someone just because they have a PHD because they're the same ones that have fricked up our planet.
And those same people will tell you this

Gonna be interesting to see outer planetary hitch hiking.

Mate is there a well-produced cartoon on YouTube that would explain this for visual learners like myself?

The wind shear would kill you at this speed. They aren’t doing more than 60-80 mph.

It's not flat, it's not round because round can be flat. Is it a sphere, probably.

So you're telling me a giant chicken laid the planets?
How fast was the chicken going when it laid the planets?
10k mph? It had to be going slower than the astronauts.

You are spinning at 1,000 mph and orbiting at 67,000 mph right now. I don't see what the big deal is.

Numbers that are used to confuse people.
That simply means the Earth makes 1 rotation in 24 hours. Which isn't even true because "science" says the Earth is 24.9k mile in circumference.
People try to equate that to driving 1k mph because it's the only comparison they have.
Thus this thread comparing going 17k mph in a vacuum vs that speed against resistance.
They are not the same.

Are there equal reactions in space?
Yes.

Newtons law is applied to gravity
Yes

Does "what goes up must come down" apply outside if gravity?
If there is an applied force on an object, the object will react accordingly, gravity included.

Now let's talk about G force outside of gravity, professor.
G-forces are simply a measure of centripetal acceleration, in multiples of earth gravity, dear student.

Oh, what's that G stand for?
See the post above ^.
If this is an elaborate troll, congrats
. If not... I think you should focus on how long the fries need to be in fryer, not physics.

It’s like they aren’t moving. It’s space. There isn’t atmosphere. It could be 1000 mi/second and it wouldn’t matter.

And you good sir I believe to have the ability to understand that physics that are planet bound are not the same as space bound.
The size of a plant determines the gforce.
This the reason they've found plants equivalent to earth but 10x size and we can't live on it because it would crush our bone structure.

Same as flying
As the jet takes off you feel the force wheels lift off and things equalize. You're going 700 mph and have no idea of it.
17.5k in a vacuum, nothing. Hollywood theater.
The gravitational pull has been reduced, thus there is no resistance.

Is anyone arguing about the perception of motion?

Until they run into something standing still.

This is nonsensical. Earth's gravity impacts the motion of the moon, the sun, and every other planet in the solar system. Being 250 miles above sea level is nowhere near "outside of gravity." It should occur to you that there is a reason they are going right at about 17,150 mph instead of something like 5,000 mph.

To be fair, there's no practical reason for the average high school or college student to understand how Newton improved Kepler's laws of planetary motion (amazingly accurate at solar system scales and beyond), why the ISS is moving at 17,500 mph, the importance of Lagrange Points and why the James Webb scope is orbiting at L2, and reasons for GPS satellite cesium beam clock time corrections per Einstein's relativistic theories, mainly related to time dilation. Physics and some engineering students yes, for students outside those disciplines that knowledge is interesting but unnecessary. Practically, IMO trig by itself is sufficient and useful for life long use. Classical mechanics, calculus or quantum theory, not so much. The OP's statements are correct; yours are not. If you disagree, then your thoughts to reconcile Einsteinian space-time gravity with quantum theory would be very interesting, the Holy Grail "Theory of Everything" in physics. Or, a simpler problem is why it would be so difficult to establish a GPS system orbiting our moon, a NASA thought experiment for many years.
Respect.

By this same line of thought, people on earths surface are traveling at:
quote:
People on Earth's surface are traveling at roughly 1,000 miles per hour (1,600 kilometers per hour) at the equator due to the Earth's rotation, with the speed decreasing as you move towards the poles where it becomes zero; meaning the average person is moving at around 930 mph (1,500 km/h

In space what is the point of reference for velocity?
Nothing is still.
