An escape velocity is the ]minimum velocity with which a body must be projected vertically upward so that it leaves the earth's surface. Escape Velocity - HyperPhysics ... Escape Velocity What is Escape Velocity ? Escape velocity is the minimum velocity required by a body to be projected to overcome the gravitational pull of the earth. It is the minimum velocity required by an object to escape the gravitational field that is, escape the land without ever falling back. An object that has this velocity at the earth’s surface will totally escape the earth’s gravitational field ignoring the losses due to the atmosphere. For example, a spacecraft leaving the surface of Earth ... What is escape velocity . How to derive its equation and calculate its value for Earth. Compare the escape velocities of several planetary bodies and the sun.
