Detailed explanation-1: -Orbital velocity is defined as the minimum velocity a body must maintain to stay in orbit. Due to the inertia of the moving body, the body has a tendency to move on in a straight line. But, the gravitational force tends to pull it down.
Detailed explanation-2: -Escape velocity is the minimum velocity required to overcome the gravitational potential of a massive body and escape to infinity. Orbital velocity is the velocity with which an object revolves around a massive body.
Detailed explanation-3: -Speed of satellite To circle an orbit of the earth, which is almost 35, 786 km far from the earth’s surface, the satellite would have to maintain a velocity of about 11, 300 km/h. This orbital speed and distance allow the satellite to revolve around the earth in 24 hours.
