Homework Help: Calculate the gravitational potential energy of a rocket

  1. Oct 22, 2006 #1
    Hi,

    I need to calculate the gravitational potential energy of a rocket that's 500km above the surface of Earth (rocket has a mass of 500kg).

    What formula would I use, and how would I calculate it?

    Any help is appreciated,
    Thanks.

    Gravitational potential energy is typically represented by [tex]U_g=-G\frac {m_1m_2} {r}[/tex] when things are high above the earth's surface.
