The gravitational pull from the earth keep the moon in its orbit.
- Well, that's the short (to the point answer). Using the example of our moon and Earth to show the relationship between them. Here is the long explanation explaining in detail how Gravity and Orbit really works in the link. More information can be obtained by going to the web-page through the "Related links" section below.
Answer #1:YES======================Answer #2:No

The Moon doesn't do any work; it is in free-fall around the Earth under the influence of gravity. The full moon is perhaps more useful than other phases, but the waxing crescent is the most beautiful.
Full Moons and New Moons are "eclipse season", since eclipses happen only at those times. They are the times when the sun earth and moon are closest to being in a straight line. So the tidal effects of the moon and the sun are working together. The sun's tidal effects on the earth are not very strong compared to the moon's, but they do have the effect of adding to the lunar tides as these times.
Any force can produce work if it causes displacement. If displacement is in opposite direction of force, work done will be negative and if displacement is in direction of force work done will be positive. If there is no displacement, work done is zero. Eg: Gravitational force pulls you down towards earth, in pulling you down it does work on you which gets stored in form of potential energy. Energy for A+
No.
the earth revolves around the sun...that's how we have night and day
no........not really:)
Answer #1:YES======================Answer #2:No
Absolutely correct answer= "the four seasons"
NO. The gravity of Earth, in conjunction with the inertia of the satellite, keeps the satellite revolving around Earth. However, the satellite doesn't get any nearer to the Earth. So, according to the laws of physics, no work is done. (I'm ignoring the fact that satellites sometimes lose height and need to be "boosted" a bit to maintain their orbits. Also, I'm assuming that the satellite's orbit is circular. If the orbit is elliptical the answer is more or less the same, but a bit more complicated.)
The shade of the earth on the moon is what causes the gibbous moon.
We would have to know the masses of the Earth and the Moon to figure that out. But I will tell you this: The minimum work done is the energy needed to get the spaceship to the point between the Earth and the Moon where the gravitational influences of the two celestial objects cancel each other. After it passes this point, the spaceship will be pulled towards the Moon by the Moon's gravitational attraction, thus eliminating the need to push the spaceship further.
If the Earth was the size of a basketball, then the Moon would be about the size of a tennis ball in relative scale. The Moon is about 1/4 the diameter of Earth, so in this scenario, its size would proportionally shrink down as well.
No. This description does not quite work becomes the moon is not a planet; it is a moon.
Well, I would say YES! It keeps the air on the earth so we can all breath, it keeps the earth from just going off into space away from our source of all our energy, the sun. It keeps us from just floating away into space. There are millions of things gravity does that is positive work. I can not even to begin to name them.
The work done by the Earth on the space station is zero since the force of gravity is perpendicular to the motion of the space station. This means that there is no displacement in the direction of the force, and thus no work is done.
