Velocity Of Satellite Formula

R 3 897 x 10 7 m the.

Velocity of satellite formula. Suspect the difference may be the result of different values used for g m earth and radius earth. Spreadsheet uses 6 674e 11 m3 kg sec2 5 972e 24 kg 6437e 06 m. 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. This is the first equation or formula of orbital velocity of a satellite.

2 a satellite is orbiting the earth with an orbital velocity of 3200 m s. What is the orbital radius. The equation is independent of mass. If the horizontal velocity imparted to the satellite is less than critical velocity vc then the satellite moves in a long elliptical orbit with the centre of the earth as the further focus.

Case 1 v h v c. 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. My results are slightly different a bit high on orbital altitude and a bit low on velocity. The escape velocity of a body is independent of the direction of projection.

The orbital velocity of the international space station is 7672 m s. 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. The term can be used to refer to either. The orbital radius can be found by rearranging the orbital velocity formula.

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 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.

In gravitationally bound systems the orbital speed of an astronomical body or object e g. The orbital velocity can be found using the formula.
