Herman Trivilino replied to the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form?.Years ago I was using a textbook that forced the students to make that choice. In other words, ##g=\pm 9.8 \ \mathrm{m/s^2}##. That was... -
Herman Trivilino replied to the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form?.I do, in the case of two-dimensional motion. Of course I choose ##\theta## to be zero in the case of one-dimensional motion, so I take...

Herman Trivilino replied to the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form?.I don't. When I write the one-dimensional kinematic equations I'm writing down the relations between components of that vector. And...

Herman Trivilino replied to the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form?.Nothing sacrosanct. It's just an issue of trying to get as many students as possible to comprehend. It's all a matter of preference.

Herman Trivilino replied to the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form?.Yes. I always stressed to my students that we have to keep these three things distinct and in the fore: 1. Vectors. 2. Vector...

Herman Trivilino replied to the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form?.But I've not seen it written that way, anywhere. By not writing the displacement vector as ##\vec{x}##. No college-level introductory...

You do not understand the unique genius of the scientific method, and therefore you do not understand anything much about physics... -
Herman Trivilino replied to the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form?.You are correct. This problem arises in physics textbooks and lectures quite often, and also in other contexts. The source of the...

Herman Trivilino replied to the thread I Topic about physics axioms, theory, laws etc...This question is better phrased as why is there a fastest speed? And why is that the speed of causality and also the speed of light?
-
Herman Trivilino replied to the thread I Topic about physics axioms, theory, laws etc...Because in 4 the speed is less than c. Here's a geometric analogy. If you stack wedges 1 and 2 (see figure) you can make the slope of...

Herman Trivilino replied to the thread I Topic about physics axioms, theory, laws etc...Einstein constructed his special theory of relativity in 1905 using these as postulates. His goal was to show the consequences of...

Herman Trivilino replied to the thread I Topic about physics axioms, theory, laws etc...Correct. Math uses deductive reasoning to reach conclusions. Science uses inductive reasoning. Of course, inductive reasoning doesn't...
-
Herman Trivilino replied to the thread I Topic about physics axioms, theory, laws etc...Not usually. The special theory of relativity is based on two postulates. I can't think of any other examples of that. It, like all...
