WebIt can be shown that a more general expression for the velocity of an orbiting satellite is = − a 1 r 2 v GmE where the mass of the satellite is negligible relative to the mass of Earth. Kepler’s Second Law can be applied (non-trivial) to calculate the position of a satellite in an elliptical orbit as a function of time.

Orbital Velocity and Altitude - How Satellites Work

WebEach planet has a different escape velocity. The object's distance from the planet's center is also important. The escape velocity from the Earth is about 11.3 kilometers (7 miles) per second. Orbital velocity is the speed needed to stay in orbit. At an altitude of 242 kilometers (150 miles), this is about 17,000 miles per hour. WebMay 28, 2024 · The object is a small sphere, decaying naturally due to atmospheric drag, on a purely ballistic trajectory with no lift or retro propulsion. I can calculate the trajectory due to drag but I don't know how to find it's speed when it reaches the point of maximum heating, at approx 70-80 km altitude. literary illusion meaning
