The Orbital Velocity Of An Artificial Satellite In A Circular Orbit

In gravitationally bound systems the orbital speed of an astronomical body or object e g.

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

Here you get a set of orbital velocity expressions that are derived in this post. Also there is also a post on the definition or explanation of this velocity. The orbital path elliptical or circular thus represents a balance between gravity and inertia. For a satellite orbiting at an altitude of half 1705911.

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 height h of the satellite above the earth s surface is take radius of earth as r e. In space gravity supplies the centripetal force that causes satellites like the moon to orbit larger bodies like the earth. 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.

And for nearby orbit. By steven holzner. V orbital r. V orbital gm r 1 2.

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. The orbital velocity of an artificial satellite in a circular orbit just above the centre s surface is v.
