    I just want to point out that the last figure shows both potential and kinetic energy. There is both potential energy at the top of the diving board that turns into kinetic as he jumps off. After he lands though that is then potential energy rather kinetic energy because he stopped the initial movement of energy. Instead this video portrays that kinetic energy is at the bottom but it's actually more potential than kinetic at the bottom.
