How do sideways velocities on the moon compare to sideways velocities on earth?

moon is actually continually falling on us! What prevents it from hitting us is the fact that it is rotating around us with a sideways velocity sufficiently high, so that by the time the Moon has fallen the 240,000 miles to the Earth, it has moved sideways about 240,000 miles, far enough to miss the Earth.

How do you compare an elephant's weight on the moon with its weight on earth?
The weight would be in the ratio of the accelerations due to gravity on the surfaces of the two bodies - approximately 1/6.
How does newtons law of universal gravitational apply to earth and the moon?
If it were not for the Earth's pull of gravity the moon would fly away from the Earth. The moon's pull of gravity on the Earth causes the tides.
What falls faster when dropped on the moon a hammer or a feather?
If they are dropped from the same height, they will fall at equal velocities because there is no air resistance and their accelerations by gravity are equal.
How does the gravity of the moon compare to the gravity of earth?
An object on the moon's surface weighs 0.165 as much as it does on the Earth's surface.
Why must motion be with respect to the oberver?
That simply means that there is NO WAY to define or measure an "absolute motion".Any experiment you do will be the SAME for different observers - in the sense that it is unaffected by relative velocities.
What force keeps the moon in orbit around the sun?
The force of gravity that they exert on each other, and the velocities of the Moon and Earth which is their "inertia".
How did neil Armstrong compare the earth and the moon?
as sisters
How do your masson the moon compare to your mass on earth?
ha
How might the composition of the moon compare to that of the earth?
it is smaller
Why does the moon orbits the earth?
Gravitational forces cause the Earth to pull on the Moon, and the Moon to pull on the Earth (Earth is about 81 times as massive). Since the Moon is travelling with sufficient velocity, it does not fall into the Earth, but rather orbits around the Earth. The mutual attractive force between the Earth and Moon, due to gravity, keeps the two bodies in a state of mutual revolution. If the force of gravity didn't exist, then the Moon would take off from the Earth in a straight line, and the Earth would likewise take off from the Sun.
How much time less then gravity of the moon as compare to the earth?
moon's gravity is (1/6)th of the earth's gravity
Do the earth and the moon move at the same speed?
As far as their motion around the Sun, they would have to, in order for the Earth and Moon to stay together. However, because the Moon is also moving around the Earth, they do not have exactly the same (vector) velocities at any time. (The Moon is 400 times farther from the Sun than from the Earth, so it is mostly affected by the Earth's gravity, not the Sun's.)
How lagre is the moon compare to earth?
1/6th the size.
Compare air pressure on earth to air pressure on the moon?
The moon has no air pressure because the moon has no air.
Why does the moon move across your sky?
The moon is fixed in our sky. The earth rotates beneath it. The moon is not fixed in the sky but orbits the earth about once a month. If it did not do that it would fall to earth (a critical fact noted by Newton when he worked out the theory of gravitation -- the sideways motion of the moon means that as it falls, it perpetually "misses" the earth). Just like the sideways motion of the earth in its orbit prevents it falling into the sun. The visible motion of the moon towards the west during the day is due to the earth's rotation beneath it (see first answer), but in successive nights it is further east.
How does the gravitational pool of the moon compare to that of earth?
An object on the surface of the moon weighs about 1/6 as muchas it weighs on the surface of the Earth.
How does the weight of an object on earth compare with it's weight on the moon?
On the Earth, the object weighs 6.04 times as much as its weight on the moon.
