In these streams, we have talked about work and energy already. However, we only did so in the case of one-dimensional systems. Since, we have started talking more about higher-dimensional systems, so it would be great to generalize these notions as well. To do so, we will need to start talking a bit about vector calculus and then apply those tools to arrive at suitable definitions for work and energy. From these, we can start exploring some interesting relations and deep results.
