How does inertia and gravity work together to produce orbit?

Answer 1

Hi. Inertia keeps the orbital body moving while gravity keeps it from escaping.

Answer 2

Inertia causes a satillite to tend to fly out of orbit (that is, follow a straight line). Gravity pulls on the satillite to keep it in orbit, together these two forces "cancel" each other out. Keep in mind that inertia is not techinically a force, simply a tendency.

Answer 3

An object in motion stays in motion in a straight line at a constant speed. If another force interferes with that motion, the motion changes. Gravity is a force that interupts an objects path. The object in motion wants to go in one direction while gravity is pulling it down toward a massive object. Gravity tries to pull the object toward the massive object, but the speed of the moving object is too great for Gravity to make an object 'fall to the ground'. So the the object in motion orbits this massive object because it wants to go one direction, but gravity pulls it down just enough to keep it from going straight, so it orbits. If the speed of the object was too quick, the object would break orbit... if the speed was too slow, gravity would make the object collide to the other object, planet, or star.

Answer 4

Inertia is the driving force of an object. Gravity keeps the object in place around it at such an arc that the object is continually falling towards the bigger object. it's complicated without diagrams.

Answer 5

What they call "inertia" is really the secret of gravity reavealed.
The production of orbit is the most difficult thing to describe and understand. What happens to the substance of space when you twist it.That is what produce energy of space.

Answer 6

that's a very long answer involved with that question...
