Question

what is escape and orbital velocity ?​

Answer 1

☯ Escape Velocity :

• The lowest velocity that an object has to escape the gravitational attraction of particular planet .

• ESCAPE Velocity = √ 2gr

☯ Orbital Velocity :

• Motion of statelite around earth orbital is called as orbital velocity

• ORBITAL VELOCITY = Vo = √ Gm / r

Answer 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.
