What are the 2 factors that newton realized that keep the earth in orbit around the sun and the moon in orbit around the earth?
Newton realized that gravity keeps bodies in orbit around each other. That's the only factor that's necessary, which is lucky, because that's the only one that exists.
What two ways the sun holds earth in orbit because of?
There are two factors at play when we are looking at satellites orbiting around another object. The same applies for a man made satellite in orbit around earth or another planet, a moon (natural satellite) in orbit around a planet, or the planets themselves orbiting around the sun. There is the satellites the tangential velocity acting away from the system and the gravitational attracting keeping the bodies close together. The satellites have a tangential velocity, they are speeding along sideways relative to the Earth (for example). If there was no gravity, this velocity would take the satellite away from the Earth, but the Earth has a gravitational force which counteracts this effect. The Earths gravitational force is constantly attracting the satellites in, against this tangential velocity. If the satellites were to slow down, then they would eventually spiral into the Earth, but in orbit there is very little drag, so the satellites pretty much maintain their speed and their orbits, though they do need a boost occasionally to keep them in orbit due to the small amount of atmospheric drag over time.
What two factores combiend to keep earth in oribit around the sun and the moon in orbit around the earth?
Only one force is required: gravity ... the gravitational attraction between the center of the earth and the center of the sun. If gravity were not at work, then the Earth would take off in a straight line, into deep space. And if another force were required, we'd be out of luck, since the gravitational attraction is the only force that exists.
What causes the earth to stay in orbit around the sun?
Gravitational attraction, by the Sun.
How do scientists keep satellites from falling to Earth?
The same way they prevent the moon from falling to earth . . . give it enough horizontal speed so that by the time gravity has pulled it down 10 feet, the surface of the earth has curved down 10 feet, so it's still just as far from the surface as it was originally. Perform this maneuver enough times, and the moon "falls" through a complete circle around the earth, without ever getting any closer to it. And scientists have nothing to do with it.
Find out the forces keep a satillite in its orbit going around the earth?
the earth's gravitational pull is just strong enought to keep it in orbit, but not strong enought, at that distance, to pull it back to earth
What two forces keep the moon and all other satellites in orbit around earth?
Gravity and Inertia
What 2 forces pull on planet earth creating an orbital path around the sun?
Gravity and Inertia keep Earth in orbit
Does the force of earth's gravity keep earth in its orbit around the sun?
You're half-way there. The mutual, equal gravitational forces between the Earth and Sun maintain the Earth's stable, closed, elliptical orbit around the Earth/Sun common center of mass.
Does the force of gravity keep the earth in its orbit around the sun?
You're half-way there. The mutual, equal gravitational forces between the Earth and Sun maintain the Earth's stable, closed, elliptical orbit around the Earth/Sun common center of mass.
What is the two things that keep the earth in its orbit around the sun?
Nitrogen levels and surface radiation.
What two forces work together to keep the planets in orbit around the sun?
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
Does gravity and inertia keep the earth orbit around the earth?
Yes. Clearly the Earth orbits around the Earth.
What to featutres of motions keep the earth in orbit around the sun?
The mutual forces of gravity between the Earth and sun maintain the Earth's closed orbit. So that's "Gravity" for number-1, that's all there is, and that's all it takes. There is no number-2.
What two opposing forces keep the moon from orbiting?
None. The moon orbits the Earth, Earth orbits the Sun. Inertia and the gravity keep the moon in the Earth's orbit.
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".
What keep a satellite in its orbit around?
Gravity wants to pull the satellite back to Earth - the speed the satellite travels around the Earth wants to fling it out into space. The two forces cancel each other out, and so the satellite remains in orbit - pulled in opposite directions with equal force.
