Answer 2

Step-by-step explanation:

In order to overcome the gravitational pull of a planet, moon or sun, an object must be accelerated to the gravitational escape velocity for that celestial body at a given altitude above the body's surface.

You can derive the equation for the gravitational escape velocity by considering the initial gravitational potential energy at the given altitude and the initial kinetic energy of the object. By comparing this total initial energy with the sum of the potential and kinetic energies at an infinite separation, you can determine the escape velocity equation.

Questions you may have include:

What are the initial potential and kinetic energies of the object?

What are the potential and kinetic energies at an infinite distance?

What determines the final equation?
