... At the points, where E U (x) , the kinetic energy is zero. Regions where the kinetic energy is negative, are called the classically forbidden regions, which the body can never reach if subject to the laws of classical mechanics. In quantum mechanics, there is a very small probability that the body ...

... From work - energy theorem : mg ( y0 − y f ) = KE f − KE0 – From this we can see that being higher initially means that you can have a higher final kinetic energy. Thus, mg(y0-y) is the part of the stored “potential” energy, which was changed into kinetic energy as the object moves from its initial ...
