So i missed a question on my practice test only on the basis that I applied ideal instead of non ideal when it came to the conversion of PE to KE. The question only asked the relationship between PE and KE for a cyclist that is riding down a hill without pedaling. Am I supposed to always take into account nonconservative forces? I swear I heard somewhere from EK for instance that you are always suppose to assume ideal and conservative forces unless explicitly stated so. Any thoughts?
When to use ideal system and when not to.
