The further from the earth's center the lower the escape velocity.

The potential is half the square of the escape velocity.

In a few seconds, they'd be ready for escape velocity.

But the escape velocity from a black hole is greater than the speed of light.

But the escape velocity was quite a bit higher than her legs could deliver.

The escape velocity required to get out of it is 11.2 kilometers/second.

The minimum speed at which this could happen is called the escape velocity.

Isn't the escape velocity less the further you are from the centre of mass?

The size of a black hole is determined by its escape velocity.

I don't know of any ship that could achieve escape velocity with a significant amount on board.
