What are the limitations of classic mechanics and which are its differences with quantum mechanics and relativistic mechanics?

Hello my fellow scientists, I'm a chemistry freshamn student and my Physics Prof. told us that we had to cover the part of all classic physics with an essay... presonally I don't think that's a good idea, I dislike essays, I'd prefer to solve a bunch of problems rather than doing this, but ehhh. So yea, from the several things I have to research I have problems explaining what do classic physics study (explaining kinetics, dynamics and statics) I can´t find that in any book, they all start with newtons amazing laws . Ohhh and can anyone tell me what are fluid dynamics, molecular dynamics in proteins and energy analysis in physical-chemical systems?? I'd be really gratefull, Thanks.
