I was wondering how verifiable is the escape velocity equation.
V=SQRT(2GM/r)
How accurately has this equation been verified?
It does not take into account dark matter.
(Related ramblings)
The escape velocity from the earth’s surface is about 11.2 km/s
But there is also air resistance. How much extra velocity (above 11.2 km/s) is required to escape Earth’s gravity?
I am not after a specific value, I would just like to know if the energy requirement increase is significant or not.
How much leeway in terms of fuel does NASA give when firing rockets into space?
