Still considering the system of the comet plus the star, which of the following statements are correct?
Along this path the gravitational potential energy of the system is never zero.
The sum of the kinetic energy of the system plus the gravitational potential energy of the system is the same at every location along this path.
The gravitational potential energy of the system is inversely proportional to the square of the distance between the comet and star.
At every location along the comet's path the gravitational potential energy of the system is negative.
