Discussion Overview

The discussion revolves around the relationship between joules and Newton's energy transfer, particularly focusing on a claim regarding the conversion of Newtons to joules and the associated exponents. Participants explore the validity of a specific statement and express concerns about its accuracy and reliability.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants question the claim that "joules are equivalent to one Newton's energy transfer across one meter," particularly the discrepancy in the exponents when converting between Newtons and joules.
  • Several participants express skepticism about the reliability of the source from which the claim originated, suggesting it contains numerous errors.
  • There is a repeated emphasis on the need for reliable resources when learning physics, with some participants indicating that the article in question is not a trustworthy source.
  • One participant asserts that the exponents for joules and Newtons should be equal, supporting their argument with a reference to Newton's Second Law.
  • Some participants express frustration with the discussion dynamics, feeling that their learning needs are not being met and that there is a lack of support from others in the thread.

Areas of Agreement / Disagreement

Participants generally agree that the source of the claim is unreliable and contains errors. However, there is disagreement regarding the level of support and guidance provided to those seeking to learn from the discussion.

Contextual Notes

Limitations include unresolved questions about the conversion process between Newtons and joules, as well as the specific errors in the referenced article that have not been fully detailed.

They said this: "Luckily, joules are equivalent to one Newton's energy transfer across one meter of stuff, which means we can still get our answer, since joules are convertible to TNT megatons. 5.37498 x 10^31 Newtons is 5.37498 10^37 joules per meter"

How? shouldn't the exponent be the same for the joules?

Please reference where this statement is taken from.
 
I suggest paying absolutely no attention to that "answer" whatsoever.

ok. why?

Because it contains a large number of erroneous statements.

like the joules not being = to Newtons, but what else?

Isn't that enough?

You yourself pointed out the discrepancy in the exponents of the "conversion".

I suspect the author's degree will be one of those "self-awarded" B.S. degrees - all B.S., no substance.

You have lots of opportunities to learn things you do not know. The internet generally is only a good place to do it if you have reliable resources. Physics Forums has a large amount of knowledgeable members and you will often get great answers. We are not a replacement for a textbook though.

becuz u guys don't want to help me learn simple things, because you clearly have your own little clique. w/e I am done here, you guys need to learn how to treat people

Nonsense. We just don't feel like pointing out every little error in someone's post online. Did you expect us to?

As pointed out, ignore the article.

You have learned something.
The article has errors.
You have pointed out one error.
Posters are agreeing with you.
Thus, you have learned that your own physics knowledge may be better than that of the author.
Thus, move on from that that article.

A blatant error such as the one below shows that the has author has taken as little as possible effort to get, or to make sure, things are correct.
Thanks to Newton and the SI unit system, this is easy to figure out. Newton's Second Law says the Force equals speed times acceleration.

If this is your question, then yes, the exponents should indeed be equal.

I honestly have a really hard time to imagine how this was the conclusion you drew from my post ...

Looks like OP has got his answer. His source is unreliable and contains multiple errors.
