What happens if a satellite speeds up in its orbit?

If the satellite is moving too quickly then the gravitational attraction between the Earth and the satellite is too weak to keep it in orbit. If this is the case, the satellite will move off into space. This occurs at speeds around or above 11,200 metres per second (m/s).

What happens to orbital velocity of a satellite as you move further away from central object?

The transverse orbital speed is inversely proportional to the distance to the central body because of the law of conservation of angular momentum, or equivalently, Kepler’s second law.

Is a satellite moving around the earth in a circular orbit accelerated?

Yes, the motion of a satellite around the earth in a circular orbit is accelerated. Acceleration depends on velocity. Velocity has magnitude and direction.

Why does a satellite moves in a circular orbit?

That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. This would cause the projectile to stay the same height above the earth and to orbit in a circular path (such as path C).

How important is the speed of an orbiting object?

If a satellite is going very fast, it can go forward so quickly that the pull of gravity can’t keep it in an orbit. If it is going slowly, it will not go forward enough to counter the pull of gravity and crash into the thing it is orbiting around.

Why does the velocity of the satellite change as it orbits the Earth?

Gravitational attraction provides the centripetal force needed to keep a planet in orbit around the Sun, and a satellite in orbit around a planet. An object moving in a circular orbit at a constant speed has a changing velocity. This is because velocity is a vector quantity that depends on speed and direction.

How are satellites placed in orbit?

All satellites are launched to space and into their orbit by hitching a ride on a rocket or on the Space Shuttle, where they are placed inside the cargo bay. There are also countries and large corporations that have their own rocket launch facilities, so they can easily send their own satellites into orbit.
