It will try to.
Throw a stone horizontally and it will land some distance in front of you.
Fire a bullet and it will land much further from you.
If two people did those things at the same time then which would hit the ground first, the stone or the bullet?
It’s counter intuitive but they’d hit the ground at the same time (ignoring air resistance and assuming the bullet doesn’t go far enough that the earth’s curve is a significant factor.)
They hit at the same time because gravity pulls both of them to earth at the same rate, the bullet goes further because it is going faster and so can travel horizontally further in the time.
What if you had a more powerful gun which shot the bullet faster? It would go further still. Now, if you imagine we live on a globe (I know, but humour me) then the ground would slope away from you. Let’s ignore hills and mountains. You should be able to see that if you shoot the bullet fast enough then the bullet would never land, it would fall but as it falls the ground slopes away. Get the speed right and it would go all the way around the earth (assuming it maintains a constant speed so ignoring air resistance). That is how orbit works.QuoteGravitational constant , oxymoronic name, changes with altitude according to the inverse square law and pulls to the centre of mass or so the theory goes.
Here you have quite succinctly shown you don’t understand English or science.
An oxymoron is two adjacent words which contradict one another. These do not.
The Gravitational constant is, as the name suggests, constant. The gravitational force the earth exerts in a body is not constant.QuoteIt 's a plane, balloon satellite, or whatever lighter than air craft they want to wow you with . It's a hologram maybe. It isn't what OP thinks it to be.
And where is your evidence for that?
The gravitational constant ,big G , is not constant . Do some research. Start here if you wish . Article from New Scientist. https://www.newscientist.com/article/dn24180-strength-of-gravity-shifts-and-this-time-its-serious/
There's loads more on tinterweb .
Watched the ISS plane fly over last night 11.40pm. Ridiculously bright for an object 250mls or so away . Apparently it's because the solar panels cover a big area and reflect sunlight. I always thought the point of solar panels was to absorb sunlight.
Are there orbital parameters for iss that allow for the alledged spin of the earth ? Surely it must be constantly accelerating ?
Earth travels around the sun , according to theory , at 66,600mph, devilish number that . Now that is 18.5 miles per second or 30kms .Iss travels at 7kms we are led to believe . How does it keep up ? How does it maintain its orbit? How do the geostationary satellites ,thousands of miles away , cope with earths motions ? There is no wonder it took a scifi writer to dream up such nonsense or nonscience.
There is no magic velocity ,in globe theory , that allows a satellite to orbit a planet , it either escapes or is pulled back to earth .
If there is ,where is the magic formula?
The value G MAY not be constant. But this is speculative if you read the article carefully.
You are mistaken. There is such a velocity: v=\sqrt{GM/r}, which was given in the post above your reply.
Why do you think satellites care about the earth spinning? Do you suspect there is a force exerted by a spinning object? Does the earth care that the sun spins?
It is difficult to reply properly when your statements are vague. What does it mean for satellites to “cope” with earth’s motions?
