Velocity Of Satellite Formula

What is the orbital radius.

Velocity of satellite formula.

Spreadsheet uses 6 674e 11 m3 kg sec2 5 972e 24 kg 6437e 06 m. Orbital velocity expression 2 step by step derivation for a mass of m on earth s surface the following is true. If the point of projection is apogee and in the orbit the satellite comes closer to the earth with its perigee point lying at 180o. In gravitationally bound systems the orbital speed of an astronomical body or object e g.

The orbital velocity can be found using the formula. The formula for orbital speed is the following. Taking the square root of each side leaves the following equation for the velocity of a satellite moving about a central body in circular motion where g is 6 673 x 10 11 n m 2 kg 2 m central is the mass of the central body about which the satellite orbits and r is the radius of orbit for the satellite. Relation between escape velocity and critical velocity of a satellite moving very close to the earth s surface.

Case 1 v h v c. This is the first equation or formula of orbital velocity of a satellite. Velocity v square root g m r where g is a gravitational constant m is the mass of earth or other larger body and radius is the distance at which the smaller mass object is orbiting. The equation is independent of mass.

Suspect the difference may be the result of different values used for g m earth and radius earth. If the moon rather than the artificial satellite orbited at 400 miles and you could ignore air friction and collisions with the earth it would have to go at the same speed as the satellite in order to preserve its close orbit which would make for some pretty spectacular moonrises. Here r r h. The orbital velocity of the international space station is 7672 m s.

The escape velocity of a body is independent of the direction of projection. Planet moon artificial satellite spacecraft or star is the speed at which it orbits around either the barycenter or if one object is much more massive than the other bodies in the system its speed relative to the center of mass of the most massive body. The term can be used to refer to either. The orbital radius can be found by rearranging the orbital velocity formula.

R 3 897 x 10 7 m the. My results are slightly different a bit high on orbital altitude and a bit low on velocity.
