What characterizes an elastic collision, but not an inelastic collision, in a closed system?
A. Momentum is conserved
B. Total energy is conserved
C. Kinetic energy is conserved
D. No external net force acts
I think it is B.



Answer :

You were close, however the answer is C. Kinetic energy is conserved. In elastic collisions, kinetic energy and momentum are conserved. In an inelastic, momentum and total energy is conserved.
