What is the force which keeps the satellite in orbit round the earth?
gravity
Is the moons or the earths gravitational force stronger or weaker?
The Earth's gravitation force is greater than the Moon, which keeps the Moon in orbit round the Earth.
What holds the moon in its orbit round the earth?
Objects are held in their orbits by the force of gravity. The Moon moves round the Earth but is continuously being accelerated towards the Earth by the mutual force of gravity. Because the Moon is lighter, it moves more noticeably. The acceleration caused by the force makes the Moon continuously curve towards the Earth but its high speed prevents it falling inwards. That is how an orbit happens.
What causes planets to orbit?
Planets are kept in their orbit by the suns gravity, yet their momentum keeps them from falling into the sun. (Thank goodness!) Planets orbit in the direction their star rotates, so in our solar system, all planets orbit in the direction of the star.
What force holds the earth in its orbit round the sun?
That's the mutual gravitational attraction between the sun and the earth.
How do people live though earth is round?
Because of gravity. Gravity is a force that pulls everything towards the center of the Earth. This force keeps people on the ground even though the Earth is round. Hope this helps!
What force keeps the earth and other planets orbiting around the sun?
2 forces keep are the key in earth's orbit: gravity and inertia Inertia is the bit that would send the earth flying off into outer space, so it can hardly be held part responsible for keeping it in orbit. As the earth tries to speed past the sun (inertia) the attractive gravitational pull force bends it from its path, so it adopts a new direction, and the gravitational force keeps on bending its path and the earth finishes up in an orbit. Much like twirling a weight on a string, where the tension in the string stops the weight from travelling straight on and away. The ancient "sling" weapon used this idea - you twirl the stone in your sling round and round faster and faster, and the tension gets bigger as the rotation gets faster. Then you release your hold and the tension is released and with nothing now to keep it "in orbit" the stone flies off at high speed (due to its "inertia").
When the earth is round why don't we fall?
Gravity is the answer. All matter, including the Earth, tends to clump together by mutual attraction. This is thought to be the work of an underlying massless particle (the graviton) that carries energy between atoms. On Earth, gravity is observed as attracting matter toward the center of the Earth, regardless of where it may be located, on, below or above the surface. The more powerful gravity of the Sun keeps the Earth in its orbit, just as the Earth keeps the Moon in orbit. But the Sun is much farther away, and for small masses such as people, the gravity of the Earth is a far more powerful pull. At the atomic level, the attraction between protons and electrons is electromagnetic -- but the attraction between protons (and neutrons) is a separate force that keeps atoms together. The macrocosmic version of this force is gravity. It is much stronger than the force exerted by the spinning Earth, which would otherwise launch matter at the equator off into space.
Why does the earth orbit round the sun?
Because the force due to universal gravitation that attracts the earth and sun toward each otherbends the earth's motion into a curve.That prevents the earth from moving in a straight line, as it would if there were no force of gravity.
What the meaning of the ORBIT?
an orbit is the circular movement of a planet going round the sun, or a moon going round a planet. Gravitaional force is what creates the orbit.
Why this satellite keeps on revolving around earth?
Which satellite are you referring to ? Satellites stay in orbit because the force trying to 'throw them out into space' is counter-balanced by the gravitational pull of the earth. Those that are revolving round the planet (as opposed to geostationary ones) do so, because they were set in a side-ways motion when they were launched.
One complete round of a earth on its orbit is called what?
One complete round of Earth on its orbit around the Sun is called a "year." It takes approximately 365.25 days for Earth to complete one orbit.
