Physics Gravity Question:

  1. Apr 29, 2012 #1
    1. The problem statement, all variables and given/known data
    A 5.00 x10^2-kg satellite is in circular orbit 2.00 x 10^2 km above Earth’s surface.
    Determine the gravitational potential energy of the satellite
    Determine kinetic energy
    Determine The Binding Energy



    3. The attempt at a solution
    I solved for gravitational potential and kinetic energy but for the binding energy i get a positive number when the answer is negative. Doesnt Binding energy = -Total energy and because the total energy will be negative, the negative times a negative will make it positive Please give me some insight
