Orbits and Gravitational Laws?

Question

If a space shuttle goes into a higher orbit, what happens to the shuttle's period?

Answer 1

It slows down. (The speed of the object orbiting Earth only by the gravitational force I meant).

For 2 reasons. firstly because the radius of the orbit becomes higher.

Secondly because Earth's gravitational pull becomes weaker. (By the Newton's equation of gravity you can see it, because gravity's force becomes weaker by a rate of 1 / r^2, where r = distance)

So as the circumference becomes bigger the period becomes higher.

Answer 2

The period gets longer for a higher orbit. That is why the Shuttle orbiting only 200-300 miles high takes 90 minutes to go around once but satellites orbiting 24,000 miles up take 24 hours to go once around. And the Moon orbiting 240,000 miles up takes a month to go around once.

Answer 3

The gravitational rules maximum somewhat do word to stars orbiting interior of a galaxy. that's a familiar regulation of gravity. additionally, you're able to understand that stars orbit ALL different remember that's inward interior the galaxy from them, no longer basically one monster physique mendacity on the middle. that's the reason galaxies can rotate almost as though they have been inflexible our bodies. Planetary structures, our photograph voltaic device being one occasion, basically orbit the verify celebrity, simply by fact the mass of planets mixed is a protracted way under the mass of the verify celebrity. Galaxies do no longer artwork this way, simply by fact celebrity hundreds upload up and somewhat are substantial in determining the orbits of different stars of the galaxy. dark remember is basically a theorized fabric which refuses participation in thermal radiation, and is undetectible to us via utilising electromagnetic observations. we don't inevitably understand no remember if dark remember fairly exists or no longer. We basically think of there is dark remember, simply by fact as quickly as we attempt to sort what motives the noted galactic rotation curve, some aspects of it do no longer look to make experience. We theorize that there is dark remember additionally contributing to the orbits of outer mendacity stars, to account for the unaccounted mass.

Answer 4

The orbit of a satellite is fastest close to the surface.
If you move it away from the surface you must slow it down to maintain orbit.
If you increase the speed of the orbit the satellite will spiral away from the planet.
If you slow it down it will crash into the surface of the planet.

Answer 5

It increases, it is now taking a longer path around the Earth and this will change the path, and shape, of the orbit.
