Gravitation Help

  1. Jan 27, 2005 #1
    Which is larger - the total energy of the 2.00 kg satellite in its 160. km orbit or the total energy in its 144 km orbit. Explain why the two answers are different.

    Ok the total energy of 2.00 satellite in 160km orbit is -6.09x10^7 J and the total energy of 2.00 satellite in 144km orbit is -6.12x10^7 J.

    How do I do the explaining part? I dont' think its simple as just saying their at different distances. Why is the satellite in the 160km orbit have a greater Etotal than the satellite in the 144km orbit?
