How does gravitational force cause the moon and artificial satellite to orbit earth?

Answer 1

No, but yes. And let's look at that, 'cause it probably isn't what you think. There are magnetic fields on the moon, but the moon as a whole lacks a magnetic field like the earth's. The earth's magnetic field is believed to be generated around the core by dynamo action. However it's generated, the earth's field is a planet-wide phenomenon to which a compass can be applied to find direction. The moon has no molten core. It has "pockets" or "areas" of "local" magnetism based on the distributed material in the crust, and on the small magnetic fields present in the alloys of ferromagnetic material there. Bottom line, you can't get around on the moon using a compass if you don't wanna get lost. A link is provided to the Wikipedia article on the moon's magnetic field(s), and the map there is probably the most helpful thing in getting a quick handle on what's up with that.

Answer 2

Yes. As an example, as the moon orbits, it influences the tides on earth. Gravity is something that anything with mass has. And the more mass an object has, the more gravity it has. People and cars and large buildings have gravity, but the actual "amount" of gravity is small because gravity on that scale isn't "noticeable" to us. But it's there. Quantum mechanical calculations have to take this into account. Even on the atomic scale.

Answer 3

The Earth's moon does have its own gravitational pull. In fact, the gravitational pull of the moon is largely responsible for tides on Earth.

The gravitational pull of the moon can also be seen in the footage of the Apollo moon landings. Without any gravity, the astronauts and the moon landers would have floated off into space rather than staying on the Moon's surface.

All bodies - even those much smaller than the moon - have their own gravitational pull, but it is only strong enough to be noticed with very large objects such as asteroids, moons and planets.

Answer 4

The earth.

Answer:

The gravitational pull present on the moon (the force tha would make you feel weight if you were there) is a result of its own mass. The pull acting on the moon comes from all other mass in the Universe but primarily the Earth and Sun.

Answer 5

Yes. Gravity attracts everything to everything else, but since everything is already moving, it all balances out.

Gravity is the force that keeps the Earth from flying off into space away from the Sun, and keeps the Moon from flying away from the Earth.

Answer 6

Gravity comes from any object with a mass. You or I have a mass, a pencil sitting on a desk has a mass, as does an atom! All these things create a gravitational field. However, out of the fundamental forces (Strong, Weak, Electromagnetic and Gravity), gravity is by far the weakest. This means that the gravitational fields of small (even by the suns standard) objects are not felt as readily by beings as small as us. The larger the mass, the more attractive it is. The mass of the earth (approximately 5.9742 × 10^24 kilograms - that nearly 6 with 24 0s after it!) is sufficient to create an acceleration towards it at the surface of about 9.8 m/s^2 - this is what we feel pulling as down to the ground. The moon, with a mass of about 7.36 × 10^22 kilograms - that's over a 100 times less than the earth - still exerts a gravitational field. However, that combined with the distance it is from the earth, means that we do not feel it's effects. That's not to say we can't SEE it's effects! The moon is responsible for the tidal waters, as it pulls water into different areas from afar.

Answer 7

The Moon orbits the Earth, the Earth orbits the Sun. Isaac Newton in the 18th century discovered that the force of gravity between a large and small object causes the smaller one to orbit round.

Johannes Kepler discovered that planets move in elliptical orbits, which was very difficult to discover because they move in ellipses with very little elongation, in other words they are almost circles, which misled all the previous scientists who did not have accurate enough observations to make the discovery.

What Newton did was to develop a theory of gravitation that said the force is an inverse-square type of force, in other words doubling the distance gives one quarter the force. He showed mathematically that this type of force gives exactly the elliptical orbits that had been discovered by Kepler.

Answer 8

No; the gravity on Earth is the result of the Earth's mass.

No; the gravity on Earth is the result of the Earth's mass.

No; the gravity on Earth is the result of the Earth's mass.

No; the gravity on Earth is the result of the Earth's mass.

Answer 9

Everything that has mass have gravity, so all the moons will have gravity. How much gravity the'll have will be dependent on the mass of the moon. A small moon with small mass will have less gravity than a big moon with big mass.

Answer 10

The acceleration of gravity on the surface of the moon ... and the weight of any object sitting

on that surface ... is roughly 1/6thof the acceleration of gravity on the surface oif the earth.
