Where did the concept and equation of work come from? It was introduced in Physics 1 with absolutely no background or proof. It was just: " we physicists define work to be force times distance." It seemed to pop out of thin air, and I gulped my pride/hate and accepted it in hopes that it would be explained later. Unfortunately, it resurfaced in physics II with electrical potential energy. And frankly, I'm going crazy not knowing the proof or how it came to be.
