Orbital velocity as a function of altitude
WebOrbital Velocity is expressed in meter per second (m/s). Question 1: Calculate the orbital velocity of the earth so that the satellite revolves around the earth if the radius of earth R = 6.5 × 106 m, the mass of earth M = 5.9722×1024 kg and Gravitational constant G = 6.67408 × 10-11 m3 kg-1 s-2 Solution: Given: R = 6.5 × 106 m M = 5.9722×1024 kg Webcalculations). The assumptions are fairly accurate for low altitude circular orbits but may lead to significant errors for high altitude or highly elliptical orbits. Figure 1.
