State condition for various possible orbits of satellite depending upon horizontal speed of projection? |
|
Answer» There are four possible trajectories of a satellite DEPENDING on the speed of projection critical velocity(Vc) is the minimum velocity required to put the satellite into orbit.let velocity of the satellite be V. escape velocity of earth is Ve The conditions for those possible trajectories are: 1. When Vc>V, the satellite will not go into an orbit and will fall back on earth at some point. 2. When V=Vc, the satellite will follow a circular path. 3. When Ve>V>Vc, the satellite will follow an elliptical path. 4. When V>Ve, the satellite will follow a hyperbolic path Explanation: the speed of a satellite depend on the mass of the Earth. The total amount of (net) WORK done by gravity as a satellite makes a complete orbit is zero. The gravitational force has a component in the DIRECTION of the satellite's motion as the satellite MOVES toward the Sun. |
