why the artificial satellite don't fall in space ?

Question

as there are many artificial sattelite send to space for the connections between us like in use of t.v, telecommunication etc . if a black hole exist why they don't fall in it ? ,as they have no gravitational force from sun ,why ? my question is related to this information .

Answer 1

They do fall. They are constantly falling.

The same rules of gravitation apply to artificial satellites as they do to natural satellites, so I am just going to call them all statellites.

One definition of an object in orbit is that the object is falling toward the larger object but is also travelling at a speed away from the larger object just enough that the object falls not onto the larger object, but just beyond the larger object.

When you throw a baseball, the accelleration you put behind the baseball and the accelleration provided by gravity cause the trajectory of the baseball to curve toward the center of the earth, and eventually it falls and strikes the earth.

The same is true for every artificial satellite in orbit around the earth: the acceleration of the rockets that put them into orbit put them into a trajectory that the gravitation of the earth is bending toward the center of the earth. However, because of the acceleration provided by the rocket, the satellite doesn't strike the earth, but is in a continuous process of falling beyond the earth, but not far enough beyond the earth to escape the earth's gravitational pull, like rockets we've sent to the moon, the sun, and the other planets.

The reason that none of the satellites we have in orbit around the earth fall into the sun is that until they are accellerated to a velocity fast enough to escape the earth's gravitational well, and the moon's gravitational well, the sun's gravitational well isn't strong enough to pull them to it any sooner than the sun will pull the earth and the moon to it.

And the same is true about black holes. Even if black holes do exist, before any artificial object can fall into it, it has to be able to escape the gravitational wells of the earth, the moon, and the sun, and any other stars along the way.

Answer 2

Things can't fall if there is no up or down or gravity.

If you are in the Vacuum of space than you float. It you are in orbit around a planet with gravity than eventually the orbit will decay and you will plummet to the ground (unless you have rockets and thrusters keeping you positioned in orbit.)

Answer 3

very good question, love to see the answer, lets wait and see or why not we try asking this question to NASA or any space station?
if you get the answer please don't forget me ,,,good luck
