The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force attracts the planets in, against this tangential velocity. If the planets were to gradually slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.
What else can I help you with?
Why planets orbite around each other rather than crash due to gravity?
They keep running away from each other.
What factors keep the planets in orbit?
Gravity and inertia
Why do planets are always in orbit?
to keep gravity going
What force works with gravity to keep the planets from being pulled into the sun?
That's "centrifugal force". It's not a "real" force like gravity, but is a convenient way of describing the effect of the inertia of the planets. (The planets would move in straight lines if they were not in a gravity field.)
What are the 2 factors that keep the planets in orbit?
The two factors that keep planets in orbit are gravity and the forward motion they gained during their formation. Gravity pulls the planet towards the sun, but the forward motion prevents the planet from falling into the sun, leading to a stable orbit.
Is the gravity on the moon enough to keep people floating away?
Yes, it is about 1/3 that on Earth.
What if the sun did'nt have gravity?
then all of the planets will just fly away in space they will just keep on flying.
What caues planets to revolve around the sun?
The sun has a large mass of gravity. And the sun uses that gravity to keep us from flying away. Even though we try to, the sun keeps us in balance. All the movement on the planets move the planets farther away if we didn't have the suns gravity. And because there is no friction in space we keep on moving around very slow. But the farther away the planet is. The slower it goes around.
Does gravity keep water from floating in the air?
yes
Why is gravity imporant?
To keep us from floating in to space.
Why planets orbite around each other rather than crash due to gravity?
They keep running away from each other.
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.
How does the grivity effect the planets and moons?
Gravity helps to keep the planets in orbit. It also helps to keep the moon's close to the planets.
What factors keep the planets in orbit?
Gravity and inertia
Does gravity keep the planets orbiting the sun?
Yes.
Why do planets are always in orbit?
to keep gravity going
What force keeps the sun and the planets in place?
Gravity. It's the weakest of the 4 fundamental forces in our universe, but still the force responsible for holding it together. String theorists suggests explains that gravity leaks down from a stronger force in higher dimensions.
