- What Is Energy? Where did it come from? 8 answers
When we talk of momentum , we can say that momentum is a measure of amount of motion contained in the body but I cannot get a similar intuition for energy energy is a measure of what? Or is it just a certain mathematical quantity that just remains conserved and is thus used for solving problems etc. And I don't seem to be satisfied with statements like 'energy is capacity to do work' because then again I ask what is work then...it's just not very clear I'm unable to get a hold of the concept..not even sure of what exactly I am confused about..maybe a historical significance of the concept of energy and the progresses made to define it might help,requesting suitable directions.
