What Determines the Escape Speed from Earth's Gravitational Pull?

[QUOTE="Bandersnatch, post: 4494401, member: 399360"] For escape velocity you're comparing the total energy at the surface of a massive body and at infinity from it. This means that the second term [itex]\frac{GMm}{R+h}[/itex] will always be zero. So the first term can not be less in magnitude than the second one.If the first term becomes negative due to too low a value of initial velocity U, it simply means that the velocity U is too low to escape the gravity of the massive body.
