A real-world roller coaster released at point A and coasting without external power would traverse a track somewhat like the figure above. Friction is not negligible in the real world. Does the roller coaster have the same energy at points B and C? Is the total energy conserved during the coaster ride? Can you account for all the energy at any point on the track?
