Understanding Joules and Newton's Energy Transfer: Exploring Equivalencies

[ReptileBaird]

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?

https://www.quora.com/Could-the-mas...se-a-change-to-Earths-orbit/answer/Idav-Kelly I am just wondering how it is possible to go up so many exponents like that from Newtons to joules...

 

[Orodruin]

I suggest paying absolutely no attention to that "answer" whatsoever.

ok. why?

 

[Orodruin]

ok. why?

Because it contains a large number of erroneous statements.

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

 

[SteamKing]

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.
