Question

Define orbital velocity. Derive an expression for the orbital velocity of a
satellite. Establish a relation for orbital velocity of a satellite orbiting very
close to the surface of the earth. Find the ratio of the orbital velocity and escape
vclocity

Answer 1

Explanation:

The lowest velocity an object must have to escape the gravitational force of a planet or an object. The relationship between the escape velocity and the orbital velocity is defined by Ve = 2 Vo where Ve is the escape velocity and Vo is the orbital velocity. And the escape velocity is root-two times the orbit velocity.
