I want to calculate the delta V needed to move objects around in a 1-d gravitational field. The relevant equations as far as I can see are the Tsiolkovsky equation,
[tex]\Delta V = v_{ex} \ln\left(\frac{m_0}{m_1}\right)[/tex]
and the equation for calculating escape velocity.
[tex]v_e = \sqrt{\frac{2GM}{r}}[/tex]
Now I'm guessing that if I want to find the delta v to get from r to R I would use
[tex]v_e = \sqrt{2GM}\left(\frac 1R - \frac 1r\right)[/tex]
is that correct?
