So far in my adventure, physics has become my gigantic boulder—a big red blood cell rolling down the hill (think of me as the stick figure, with stick figure arms pointing straight up running from that energized boulder). I hear the word physics every day.
I’m thinking physics is a subject like English grammar. Who cares if it’s potential energy or kinetic energy, just as who cares if it’s restrictive or nonrestrictive? It only matters in English when someone who is in hyper-grading mode gets perturbed about comma usage, and wants to use his or her new red pen to mark up papers. Kick ass content? No, that is not as important as whether or not the comma is there. His 12-year-old son John was hit by a car. Oh My God! There needs to be a comma after son and after John!
This is how I am feeling about physics. The vessel with a bulge from an aortic aneurysm is ready to blow. Oh my God! Is that potential energy or kinetic energy?
