why work is defined? and when it was defined ( approximately) and who has defined it? It is one of the most important things in physics and I am wondering that is it defined only for make the seeing and understanding things in the nature easier?
Actually I am also wondering about when and how did people approach mechanical or any physical things through conservation of energy or work-energy theorem.
Everybody knows;such as, F=ma or orher laws details, but I ve never heard any historical things about energy, work, conservation, etc.
Thank you all in advance...
