The irony of a Republican lawmaker trying to make this point is unbelievable…

Make sure we read table 2 in the paper. The reality is the people behind this study is urging folks to not draw strong conclusions from this study.

It depends on the state. Oklahoma is ranked 49 of 50 for its k-12 public education system, and we are seeing evidence of this here.

I am a physics teacher in a New Jersey high school (and not even a high ranked school) and I would say that a majority of the teachers are true professionals with masters degrees in education. New Jersey is ranked 2 of 50 though (just behind Massachusetts). We also see teachers salaries around and over $100,000 in New Jersey so it entices more people to become teachers and treat the job very seriously.

You are a waste of time

I used the higher level 3-dimensional definition of work, and you told my I was wrong and provided my the high school level 1-dimensional definition of work. Then you hang it over my head and try to correct me as if my definition is incorrect.

The fact is your knowledge of physics is so low that you didn’t even know this nuance; and you are not arguing in good faith because this is something you easily could have looked up and realized if all you cared about wasn’t “being right”.

It’s very apparent that you are not a good faith discusser and your knowledge of physics is very low.

I’m checking out of this discussion

Not AI. I’m in academia, so I write academically.

I specify “physics work” to mean physic’s definition of work (dot product between Force and Displacement).

And to not connect the importance between the electric and magnetic field as it pertains to the the electrostatic force and magnetic force reveals your basic understanding of the physics. Hence, why your prior comment was so problematic…

Oh boy, this is very incorrect, because it sounds like you are attempting to explain magnetism with electrostatic forces. Here is a basic model which separates the difference between the two:

1. Electrostatic forces are caused by the electric field. Something produces an electric field simply by having an unbalanced charge. Positive attracts negative, negative repels negative, positive repels positive.

2. Magnetic forces are caused by the magnetic field. Something produces a magnetic field by having an unbalanced charge AND is moving.

This is why when trying to explain how solid magnets work, we focus on the electrons because electrons are charged particles that are always moving. So they produce both an electric field (being charged) and a magnetic field (being a moving charged system).

Rhaedas is sorta correct. Any solid system has the capability of being a magnet, but this takes an incredible amount of physics work where iron is special. Iron’s electrons are able to easily maintain a synchronous orbit with each other which results in magnetic forces being observable at a macroscopic scale (seeing iron magnets pull on each other). In most other materials, the electrons orbits are chaotic, so even though magnetic fields are still being produced by their electrons, the lack of order results in no magnetic force being observable on the macroscopic scale; but if you place this non-iron material within a very strong magnetic field, you may be able to align their electrons orbits so that it becomes magnetic on the macroscopic scale (like iron).
