also be V2/u/r (putting - = 0). Hence this velocity is called the velocity from infinity, or the parabolic velocity.The parabolic velocity due to the attraction of the Sun is,at the mean distance of the Earth from the Sun, equal to26-2 miles per sec. At this distance, a body projected in any Q 226… … Fig. 79.—Velocity in an Elliptic Orbit. From the above considerations, the following simple methodof representing the velocity of a body at any point in anelhptic orbit may be derived. If about S (Fig. 79) a circlebe described of radius equal to the major axis of the elhpticorbit (2a), then the…
