Physics is in dodgeball no matter what you may think. There is kinematics along with work and energy. This is almost all in the throw of the dodgeball and how you hard and fast you can throw the dodgeball.
The energy is used for the ball through the air. if you throw the ball it has a certain kinetic energy as it flies towards its target. The energy of this is based on how fast you can get the ball with the initial velocity and the kinetic will remain the same if you neglect air resista
Diving uses physics because it is all about the movement of the diving board and person. The diving board and the person each have different physics uses but they work in harmony to get the 'job' done. Diving uses so much physics and we have explored each section of the physics.
The board uses physics by giving off energy. The potential and kinetic energy work together to fling the person into the air and give the maximum height so the person can do what dive he/she is doing. The energy is tr
