Things, moons or other objects, stay in orbit aournd whatever they orbit becasue they are moving at just the right speed. As the object falls X distance down from an orbital height of Z, it also moves Y distance horizontally. That Y distance is just enough so that at the end it is at Z distance above the surface because the surface below is round and movement puts it over a part that is curved "down."
This is an awkward description of free fall. The object is always falling down but its sideways motion keeps it at the same height above the planet.
Same as any object in any other orbit. The central body (Jupiter in this case) attracts the orbiting object (Jupiter's moons, in this case), forcing them into an elipse around it.
Jupiter is the largest planet in the solar system and as such has a tremendous gravitational well. This gravity is what has enabled Jupiter to attract and keep in orbit its 67 moons.
The moons stay in orbit around Jupiter by the force of gravity.
Any moon is held in orbit by gravity, just as the planets are held in orbit around the sun by gravity.
Jupiter has an enormous amount of mass. Amounts of matter that large create enough gravitational pull to hold another body in its orbit (The Sun has countless objects orbiting it, but only relatively few of these objects are remarkably large). The moons don't fall into Jupiter because the forces in question are in constant "struggle." The moons are constantly trying to move in a straight line, but the gravity pulls them in at a relatively uniform rate. These two forces keep the moons moving in a certain circular path around the planet. Since Jupiter's gravity and the amount of space around it allow for it, it has dozens of natural satellites, 3 of which are larger than our moon, one of which is slightly smaller, and the rest of which are far smaller than our Moon.
gravitational force.
The moons stay in orbit around Jupiter due to the gravitational pull of the planet. As of June 2014, Jupiter has 63 known moons.
yes and no there;s no answer
Gravity holds satellites in orbit.
Gravity, just like our moon. gravity pulls it around

bob is jupiter and he grabs the back when they go away
Io, Ganymede, Callisto, and Europa stay in orbit with Jupiter cause Jupiter has a strong gravitational pull on celestial bodies around it.
cause they stay i orbit because of jupiters gravity not there own so jupiter would suck the gas from its moons but not vice versa
because the planets' gravity pull them so that they do not go away and the moons revolve around them with a constant speed so they stay in their orbit
