    What is the change in energy required for the Earth to escape the Sun's orbit?

    Well you're the one who brought it up... After a half of hour of explaining something that doesn't seem to be that useful for the actual problem, I still don't get how to do the problem. Surprise?

    What is the change in energy required for the Earth to escape the Sun's orbit?

    Wouldn't it be just close to 0? (In a negative number) I also have a test on this tomorrow so if you're going to take a really long time to explain this might as well tell me now.

    What is the change in energy required for the Earth to escape the Sun's orbit?

    Maybe it's so simple that it's under my nose but isn't that not possible for it to be 0? Can't it only approach 0?

    What is the change in energy required for the Earth to escape the Sun's orbit?

    So I would put the distance between the Earth and sun's orbit for r? Then just sub in the rest of the values?

    What is the change in energy required for the Earth to escape the Sun's orbit?

    I guess greater than 150 000 000 km, but how would I use that?

    What is the change in energy required for the Earth to escape the Sun's orbit?

    Yeah but I don't get how to calculate final energy if the Earth is leaving the sun's orbit.

    What is the change in energy required for the Earth to escape the Sun's orbit?

    Homework Statement Determine the energy and change in orbital speed required for the Earth to escape from its orbit around the Sun. Homework Equations I guess: Change In E = E total of o - E total of s (Egs) E total of orbit = (0.5)Eg of oribit The Attempt at a Solution Don't really know...
