Gravitational Equilibrium: A stable orbit of an object of mass m around another object of mass M requires that the energy of motion or “kinetic” energy of the object be a certain proportion of its gravitational binding energy or “potential” energy. The kinetic energy, KE, is defined KE = 1/2mv^2 where m is the mass of the object and v is its speed. The gravitational potential energy is defined as U = -(GMm)/(r) where G is the gravitational constant of Newton’s so-called Universal Law of Gravitation, M and m are the masses of the interacting objects and r is the radius of the orbit. The total energy, E, of the object of mass m is the sum of its kinetic and potential energies, E = KE + U. Note the minus sign in the definition of potential energy. This…arrow_forward
