    I just wanted to make sure I got this right before I put it down, cause I'm not exactly sure...

    what do. I know it's like something to do with proportional gravity with distance, but I can't figure out what formula to use. Perhaps the law of universal gravitation? But I don't know how to use it with these units, along with not knowing the probe's mass...I don't think its the right formula ._.

    F = G(mM)/r^2 works because you have force, 600 lbs; M, mass of the Earth; G, gravitational constant; and r, 10000 miles. Solve for m and then solve for F at the altered r's.

    Don't get hung up on the units, it's about the two things being proportional to eachother.
    The universal law of gravitation can be simplified with what you've got to F α 1/r^2, so if r is doubled, F will divide by 4 ect.

    I'm tired so sorry if this isn't very clear.

    That's a little elegant for such a simple problem.
    I clearly prefer brute force for such things but your answer is objectively better.

    I knew I was overthinking it...thanks guys.

    Physics is actually usually something I've enjoyed so far in college (just Intro to Physics for the time being), but it becomes really easy to try too hard on some questions when they're posed in ways I've never seen before :\

    Just wait for quantum.

    Chemistry's always been my thing... but Physics is a troll. >:c

    Opposite for me. I kinda very much hated chemistry and AP Bio was the lowest grade I had in high school. It was a mix of my laziness back then and my complete incomprehension of the material I think.

    For me, Chemistry tended to be in vein with Algebra, which was the only math I excelled in. But I agree that Biology was the worst science. Nuthin' but low B's and C's. D;

    The Force is too abstract a concept for you plebs to understand

    Yeah, that may not seem so bad on the outside... but having everybody else around you get straight A's... you get last place in the class ranking. .__.

    Oh, true dat.

    Thank goodness my major doesn't require any type of science. *sigh*
