    Gravitational Energy of Earth<Moon (what distance)

    Thanks and this is a question on an assignment I am doing.

    Gravitational Energy of Earth<Moon (what distance)

    I obtained mE/R2 by cancelling things from each side of the equation

    Gravitational Energy of Earth<Moon (what distance)

    I guess it would represent Fg/ G mM. Am I going about this in the wrong way? I am having trouble understanding.

    Gravitational Energy of Earth<Moon (what distance)

    Okay, so I would get something similar to what I had? mE/ R2 = mM/ (R-r)2 Then plug in R and solve for r? I think my problem is more with the algebra involved but maybe I am plugging in the wrong numbers...

    Gravitational Energy of Earth<Moon (what distance)

    Homework Statement Not give any information just the equation Fg= G m1m2/r^2 Supposed to find the distance at which the moons gravity has a greater force on a spacecraft than the Earth does. Homework Equations My prof told me to put G m1m2/r^2= G m1m2/r^2 and substitute one r in for another...
