Question

what is the defination of orbital velocity and escape velocity​

Answer 1

❣️​Hola mate,

❣️​Here is your answer.. :)

(｡◕‿◕｡)❤

Orbital velocity is the velocity with which an object revolves around a massive body.

Escape velocity is the minimum velocity required to overcome the gravitational potential of a massive body and escape to infinity.

Explanation:

The velocity required by a body to escape from the earth’s gravitational field is called escape velocity.Its value is 11 km/s.Orbital velocity is the velocity required for the satellite to move in the earths orbit.Its value is 8 km/s or 29000 km/h.
