In this lesson the professor study in more details the two-body problem with central forces, how it is reduced to the equivalent one-body problem, classification of the orbits with the help of the Kepler potential and start the derivation of the equations of motion and possible solutions (see Bertrand's theorem). In this lesson the professor give the homework number 2 (Homework.2)

Kepler's Laws Tutorial In this video you will be introduced to Kepler's 3 laws and see how they are relevant to orbiting objects. The video also makes use of computer simulations created by PhET Interactive Simulations, University of Colorado.
