Energy of a Binary System (Gravitation)

Click For Summary
SUMMARY

The discussion focuses on calculating the kinetic energy and total mechanical energy of a binary system consisting of two identical spheres orbiting their common center of mass. The gravitational force is defined by the equation F = GM^2/2R, where G is the gravitational constant, M is the mass of each sphere, and R is the radius of their orbit. The kinetic energy (K) is calculated using K = 1/2MV^2, and it is established that the total kinetic energy must account for both spheres, thus requiring the addition of their individual kinetic energies.

Homework Statement


What is the kinetic energy and total mechanical energy of a binary system of identical spheres orbiting around their common center of mass?
M = mass
R = radius

Homework Equations


Force of gravity = GM^2/2R
K = 1/2MV^2

The Attempt at a Solution


I don't know whether or not you double the kinetic energy since there are two spheres.
 
Physics news on Phys.org
Of course you would have to add the K.E of the two spheres for the total K.E.
And your eqn. for force is wrong??
