Final Jeopardy Physics as a Science

Final Jeopardy the foundation of biology is chemistry and the foundation of chemistry is physics. it is about the nature of basic things like forces, energy, and motion. the ideas of physics extend into more complex sciences. you can better understand science in general if you understand physics.
