The Orbital Velocity Of An Artificial Satellite In A Circular Orbit

And for nearby orbit.

The orbital velocity of an artificial satellite in a circular orbit.

In space gravity supplies the centripetal force that causes satellites like the moon to orbit larger bodies like the earth. The orbital path elliptical or circular thus represents a balance between gravity and inertia. You can visit our post on quick listing and descriptions of these satellite velocity expressions. Orbital velocity velocity sufficient to cause a natural or artificial satellite to remain in orbit inertia of the moving body tends to make it move on in a straight line while gravitational force tends to pull it down.

The term can be used to refer to either. V orbital r. The height h of the satellite above the earth s surface is take radius of earth as r e. In gravitationally bound systems the orbital speed of an astronomical body or object e g.

V orbital gm r 1 2. The orbital velocity of an artificial satellite in a circular orbit just above the centre s surface is v. Here you get a set of orbital velocity expressions that are derived in this post. Thanks to physics if you know the mass and altitude of a satellite in orbit around the earth you can calculate how quickly it needs to travel to maintain that orbit.

For a satellite orbiting at an altitude of half 1705911. An artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of the escape velocity from the earth.
