The key to making a concise mathematical definition of escape velocity is to consider the energy. if an object is launched at its escape velocity, what is the total mechanical energy etotal of the object at a very large (i. e., infinite) distance from the planet? follow the usual convention and take the gravitational potential energy to be zero at very large distances?
