Two Satellites Are In Circular Orbits Around The Earth One Is 150 Km

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.

Two satellites are in circular orbits around the earth one is 150 km. Clarke in the 1940s as a way to revolutionise telecommunications and the first satellite to be placed in this kind. The orbit for satellite a is at a height of 360 km above the earth s surface while that for satellite b is at a height of 720 km. Our computation for the special case of circular orbits will confirm this. An object in such an orbit has an orbital period equal to the earth s rotational period one sidereal day and so to ground observers it appears motionless in a fixed position in the sky the concept of a geostationary orbit was popularised by the science fiction writer arthur c.

Consider a satellite of mass m in a circular orbit about earth at distance r from the center of earth figure 13 12. The motion of objects is governed by newton s laws. The same simple laws that govern the motion of objects on earth also extend to the heavens to govern the motion of planets moons and other satellites. In space gravity supplies the centripetal force that causes satellites like the moon to orbit larger bodies like the earth.

A geosynchronous earth satellite is one that has an orbital period of precisely 1 day. When the orbital radius is large the period also will be large thus the one at 160 km will have the larger period. The orbit for satellite a is at a height of 539 km above the earth s surface while that for satellite b is at a height of 876 km. Find the orbital speed for a satellite a and b satellite b.

Which satellite has the larger orbital period. One is 150 km above the surface the other 160 km. Comparison of geostationary earth orbit with gps glonass galileo and compass medium earth orbit satellite navigation system orbits with the international space station hubble space telescope and iridium constellation orbits and the nominal size of the earth. Calculate the mass of the satellite.

Two satellites are in circular orbits around the earth. Two satellites are in circular orbits around the earth. It has centripetal acceleration directed toward the center of earth. We focus on objects orbiting earth but our results can be generalized for other cases.

Orbital period and speed two satellites are in circular orbits about earth. Such orbits are useful for communication and weather observation because the satellite remains above the same point on earth provided it orbits in the equatorial plane in the same direction as earth s rotation.
