Before the marble starts rolling, it is potential energy. Once it is rolling, it is kinetic energy. You know it stays the same because the marble probably would not be rolling if it weren't. All that's happening is that the ball is rolling faster because of gravity.
<span>Gravity assists the marble, leading to conservation of energy. The
stored energy is release as momentum, the output of energy is constant.</span>
