... 5. (8 points) In introductory physics one learns the formula F = ma, connecting the force on an
object, F , with the mass of the object and the acceleration that the object experiences under the
force. One also learns the formula p = mv where p is the momentum of an object, m is the mass,
and v is t ...

In physics, the n-body problem is the problem of predicting the individual motions of a group of celestial objects interacting with each other gravitationally. Solving this problem has been motivated by the desire to understand the motions of the Sun, Moon, planets and the visible stars. In the 20th century, understanding the dynamics of globular cluster star systems became an important n-body problem. The n-body problem in general relativity is considerably more difficult to solve.The classical physical problem can be informally stated as: given the quasi-steady orbital properties (instantaneous position, velocity and time) of a group of celestial bodies, predict their interactive forces; and consequently, predict their true orbital motions for all future times.To this purpose the two-body problem has been completely solved and is discussed below; as is the famous restricted 3-Body Problem.
