why the moon doesnt fall in the earth by the effect of gravity?

Answer 1

MJ is absolutely correct. As the moon 'tries' to continue on it's course, Earth's gravitational pull keeps it in orbit. Millions and Millions of years from now the Moon will eventually crash into Earth. Much like Earth will eventually crash into the Sun, as the Sun's and Earth's relationship is similar to that of the Moon's and Earth's.

Answer 2

ohh my god, all the answers for this question has been by people that are in need of a education, look I'll post the real answer from a cut and paste that I ansered a few months ago, god help those poor people.

Great question.

The reason that they don't collide is that the moon is moving to fast.

Check this out- when the space shuttle is up in space it is only about a 100-150 miles up there. Why doesn't it just fall out of the sky and crash into the planet?

Well the answer to why things don't fall out the sky is because they are in orbit- duh-. The space shuttle is not only up in space it is also moving sideways at a tremedous speed. The shuttle IS falling out of the sky, but the reason it doesn't ever hit the ground is all that sideways motion. Everytime it starts falling, the earth has moved out of the way ( sideways- remember) so it changes direction and starts to fall again, well guess what the earth has moved out of the way again. This keeps repeating and repeating. in essence anything in orbit- satelites, moons, and space shuttles are always falling but they never seem to get there. That is why the moon never hits the earth. It's important to remember that just because you are in space does not mean gravity is not pullin you down. I assure you if the shuttle was somehow able to suddenly stop it would fall out the sky like a rock. The reason the people in the space shuttle are floating is because they are falling and not because they are in space.

I just have to add a little more to this statement- You know that in freefall ( you jumped out of a airplane ) you can't feel gravity and there is no up or down or sideways. The same thing with being in orbit since you are always falling you can't feel gravity either. One other thing the people that wrote first on this question really need to double check their facts. The Perfect distance and gravity cancelling out stuff is wrong. The moon could and used to be much closer to earth. It also went around earth much faster, but because of tidal action the moon has slowed down and gone into a farther out orbit. The moon even today is leaving the earth at about three inches a year. It is slowing down and so is our day- our day is getting longer because of the moon

Answer 3

the reason that the moon isn't pulled into the earth is due to centrifugal force- the force that pushes an object outward as it rotates around another object. It's just like putting water in a bucket and spinning it around by the handle- no water falls out because centrifugal force pushes the water into the bottom of the bucket.

With the moon, the centrifugal force from it rotating around earth is similar to the pull of gravity, so they create a balance of forces where the moon stays in place in its orbit around the earth.

Also, it is interesting to point out, that an orbit in physics is really an object falling at a rate equal to the curvature of the earth as it orbits around it-

Answer 4

Moon is always trying to go away from Earth(centrifugal force because it is revolving around earth). But Earth's gravity is not letting it go.

Since the force of gravitational attraction(Centripetal force) is equal to the centrifugal force it stays at a particular distance.

Force of gravitational attraction = Centrifugal Force of the moon.

Answer 5

because the gravity pulls the moon toward the earth but inertia keeps the moon in motion around the Earth. they say that eventually the moon will crash into the earth.

Answer 6

the moon in its orbit has outward INERTIA. This counters the moons pull on earth and earths pull on moon. Without the gravity of moon/earth the moon would leave earth.

Answer 7

moon is affected by two forces- earth's gravity & the centrifugal force. the resultant is the circular motion of the moon around the earth.

Answer 8

the moon don't fall because the gravity in space keeps the moon stay inside space.

Answer 9

There is no gravity outside of the earth's atmosphere - that's why astronauts float in space!

Answer 10

It's in orbit around the earth; if, for some reason, it stopped moving around its orbital path, it would certainly collide with earth, but stopping it from moving would take a phenomenal amount of energy.
