Herman Trivilino replied to the thread High School Understanding Newton's Third Law and the Net Force on Objects.Suppose you have the following three forces, all measured in the same units: ##7 \hat{i}, -4 \hat{i}, -3 \hat{i}##. They all lie along... -
Herman Trivilino replied to the thread High School Understanding Newton's Third Law and the Net Force on Objects.Even in one dimension you can have three forces adding to zero. It wouldn't make sense to say that they are equal and opposite.

Herman Trivilino replied to the thread Finding proper value for centripetal acceleration in a plane rising up.True. But the problem implies that it's a coordinate acceleration of ##6g## in this particular scenario that causes the blackout. So...

Herman Trivilino replied to the thread Finding proper value for centripetal acceleration in a plane rising up.If you have an upward force that would create an upward acceleration of magnitude ##7g## and a downward force that would create a...

Herman Trivilino replied to the thread What did you do with your old college textbooks?.Ha ha. Good one. By then Dirac's formalism may be front and center. Or it could be an old dead end. Or anything in between.

Herman Trivilino reacted to Meir Achuz's post in the thread What did you do with your old college textbooks? with
Haha.
I am saving the best of the advanced books for my granddaughter. I want her to read Dirac's Quantum Mechanics before she gets confused... -
Herman Trivilino replied to the thread High School Potato paradox.The potatoes are almost all water. Cutting the amount of water in half cuts the amount of potatoes in half. What's "paradoxical" is...

Herman Trivilino reacted to Rick16's post in the thread Undergrad Potential energy of a system of particles with
Like.
Thank you. This is it. It is not even new to me. I read about it probably more than once, but I had completely forgotten about it. This... -
Herman Trivilino replied to the thread Undergrad Potential energy of a system of particles.By convention we usually assume that as the separation distance increases beyond all bounds, the potential energy approaches zero...

Herman Trivilino replied to the thread What did you do with your old college textbooks?.There are lots of opportunities to sell your textbooks to places like this. In my experience they won't give you much if anything for...

Herman Trivilino replied to the thread Other Is having bad resources from university normal?.Yup. Many students have an answer-making strategy, using it in the hopes of passing a class. They lack a sense-making strategy. Then...

Herman Trivilino replied to the thread Undergrad Why is thermal energy treated differently than other kinds of energy?.Excellent answer to the OP's question. In principle it is indeed an issue of being practical. Overwhelmingly so.

Herman Trivilino reacted to Demystifier's post in the thread Undergrad Why is thermal energy treated differently than other kinds of energy? with Like.
In principle, we could completely ignore statistical mechanics and thermal energy, and explain everything as you would like, in terms of...

Herman Trivilino replied to the thread Other Is having bad resources from university normal?.Well, which is it? Fine or awful? Your "scripts" seem like a typical textbook to me. Sometimes they just don't match your learning...

Herman Trivilino replied to the thread Other Is having bad resources from university normal?.No. Based on the OP's response they contain course material. Plus, you never get more than one syllabus and the OP has referred to...
