PE of a Satellite: -GMM/R Why the Minus Sign?
Satellite Potential Energy is defined by -GM1M2/R2. How can energy be minus?The explanation is given and comment is made that the equation must be limited to CHANGE in PE solutions. The further out a satellite the larger the PE. However, individual values of energy can be assigned negative. KE=GMM/R PE= - GMM/R Total Energy = -GMM/2R
