Yes it is relevant.
Momentum, velocity, etc in driving; collisions, spin, etc on the pool table, electromagnetism as explanation of spirituality. And those neat mini flashlights for my keychain.
many many many times
Yes. But I loved all science courses. Think of it and all seemingly irrelevant courses as exercises for your brain. "Use it or lose it". And in that context all classes boring to you become relevant. If nothing else you learn why sunglasses work and you may one day power your car with a potato.:) (Physics humor).
I don't know.
I am college edgucated, and have taken Masters level courses on physics. I'm totally interested in physics, but most of it has be useless.
Newton's laws have been pretty much all I need. Heavy chairs in my living room often require friends to lift. Doing 50 mph and hitting a tree will probably kill me, and try as I might, pushing on that box in the uHaul will NOT make it fit in.
With all of that said, I still waste hours thinking about m-theory and quantuum entanglement + beer is a way to get me talking for hours.
Your milage may vary.
except Newton's third law of motion
