Which of the following best defines an elastic collision between two atoms in one dimension when no external forces act during the interaction?
(a) Only the total momentum of the two-atom system remains constant, while kinetic energy may change.
(b) Both total momentum and total mechanical energy (potential + kinetic) of the two-atom system remain constant.
(c) Both total momentum and total kinetic energy of the two-atom system remain constant.
(d) Only the total kinetic energy of the two-atom system remains constant, while momentum may change.
