1. ## Force/ gravity/ mass/ acceleration

And Actually, I think I’m getting it, but I searched the number of times the word pull and push showed up in just one volume of a University Text and the score was 226 for pull, and 187 for push. Note, this was entirely in interest of their being anthropomorphic terms of little use in physics, yet still extremely useful unless they are used as terms of physics. Which isn’t exactly what you said I misunderstood the application, you wrote push (versus) pull is not useful. I could have saved myself a lot of mental exercise had I read and understood correctly the first time. Sorry, and thanks.
2. ## Force/ gravity/ mass/ acceleration

You forced me to Google, thank you . I will disagree until I find a reason to ag🤣ree . I looked up Ubi materia ibi geometria also , in the description the statement is made that nature and mathematics are intimately connected. There is a PDF I intend to read to see if it allows me to continue to disagree. 👍
3. ## Force/ gravity/ mass/ acceleration

No. I don’t think it would have made a difference then, but I don’t know. There was a tumor I was living with unknowingly. A few years ago they took it out. Background wise unless you consider YouTube and or SFN post secondary education the answer is no
4. ## Force/ gravity/ mass/ acceleration

So there is a distinction there is F=ma push then there is F=GMm/R2 pull F =ma seems incomplete as a formula because it only accounts for how m is affected by acceleration, but what it seems to me doesn’t matter, because then, who? I think it is credited to Einstein, says acceleration is the same as gravity. So if F= ma then gravity can not be a force because you have to multiply acceleration which is the same as gravity times mass to get what is called force, so gravity and force can not be the same thing. Is this why it is said that gravity is not a force?
5. ## Rotation effect on gravity?

This is where I got the word lift. Not arguing just saying. Not certain if I added this picture correctly? Guess I have to hit submit to find out… note it is not a link, just part of a screenshot.
6. ## Force/ gravity/ mass/ acceleration

Okay, I was thinking for the first question that if both ma and GMm/R2 equaled force I could write it F=ma=GMm/R2 . Which is not exactly how I wrote it the first time but I borrowed the shorthand from swansont for the latter portion. What I thought I was writing is force equals mass time acceleration ,and force equals G times mass one times mass two divided by the radius squared. Since force is described as equal to both expressions. I assumed it would be okay to write F=ma=Gmm/R2 since the expression on each side of the equal signs I presumed to be equal. As for the second question. Are you saying that by canceling mass out, force and acceleration are shown to be the same?
7. ## Rotation effect on gravity?

Thanks , I don’t write or think fast enough. I’ll read and think on this a while.
8. ## Rotation effect on gravity?

Doesn’t F=GM1M2/R2 apply to me and the earth? At a spin of 28,437 km per hour we lift off. My assumption is that in order for that to happen the acceleration due to spin would have to exceed the forces connecting us.
9. ## Force/ gravity/ mass/ acceleration

Okay… I’m nearly 70 years old, and not in school. I’m pretty sure the rules of the forum will allow you to elaborate.
10. ## Rotation effect on gravity?

I read that Earth would have to spin at 28,437 km per hour to cause us to lift off the surface. I’m assuming at that point we would effectively be weightless. Seemingly throwing a wrench into F=GM1M2/R2 , so what effect would it have on the moon?
11. ## Force/ gravity/ mass/ acceleration

I merged two formulas for Force I saw in a video. First - Did I do it right? F = ma= (G*M1*M2)/R2 1. F = ma 2. F = G M1M2/ R2 Second- If it is right does G/R2 represent the acceleration part of F= ma ?
12. ## jajrussel

What a chore it was for an old man to figure out how to make one of his pictures small enough to use here without learning how to use an image resizing app! I had to paste it to a document, shrink it, do a screen capture, then crop it, until I finally stopped getting that dreaded “the image is to big, so it was skipped” message… 🤣 Just saying hi. 👋🏻

13. ## Why Is Paganism Rising?

I remember reading that the root of the word pagan was essentially equal to peasant/not of the city. Apparently, now it is said to be the term that Christian Romans etc. used to allude to anyone not of the Abrahamic religions generally as a slur. My observation is that pagans seem to prefer the peasant/not of the city referral. Was it the video thumbnail that prompted the question. 😂 I didn’t understand what was written in Wikipedia any more than I did the comment. I assume by being an influence on those who grew up run the Navy? I remember hearing that most Hippies grew up to be Bankers, Doctors, Lawyer's, and such. I don’t know that George got that memo, but he was a good influence on some until the end.
14. ## Why Is Paganism Rising?

SFN may not approve of video's, but upon hearing about the naked girls, hmm. Oh yes, why is Paganism rising? Having once followed a major religion I found that my peers were more accepting of those called pagan. It’s kind of an oddity to me, but I could never quite get it right when asked what I believed. Apparently, it’s conditional that you absolutely agree, and rarely did I meet someone who would agree to disagree. Maybe it was just me, but I feel more comfortable around people more open to differences. Paganism is generally accepted as eclectic. It’s definition not written in stone to the extent that major religions are, or for that matter to the point where followers of Heathenism, or Wicca seem to be staking out their territories within what the major religions call the pagan community. I remember when the Geraldines would issue challenge to name the god and goddess as writ of proof. Which, I never really understood because everyone supposedly knew that aside from being sacred those names were secret. But, why is Paganism rising, most simply the access and somewhat anonymity of the internet . Yes I know the perceived anonymity is pretty much a smokescreen, but if you watch the videos those claiming to be Pagan mostly cling to eclecticism. At least that is my perception, and my belief is, that is what makes it more appealing as a label one would feel comfortable wearing. In their videos Pagan personalities are almost always esthetically pleasing in both appearance and personality, so I would be surprised if belief in Paganism wasn’t rising. I didn’t watch the video so I don’t know if the question was actually about the video, but when it comes to matters of religion sometimes the question only presents to create a perception that doesn’t actually exist, which in the right atmosphere would definitely lead to a challenge for data. Often that is the case, but personally I would like to think that an interest in Paganism is rising, because I perceive it as eclectic, and I like that some people that are more open to differences do actually exist as a community that I can be a part of. 🤔 so long as they don’t ask for money…
15. ## Aether

Apparently I’ve misunderstood what they meant by stationary, but still as I read about it, it is still confusing. It says ( the ether has to be remaining stationary with respect to the star as the earth moved through it. ) looking at their picture I can only assume this means what? I don’t know, because all my guesses say why would they think they could recreate a situation that seems implied by that statement?
