Did Newton Predict Antigravity and Weight Loss Using Velocity?

AI Thread Summary
The discussion centers on whether Isaac Newton predicted a connection between velocity, antigravity, and weight loss. Participants clarify that there is no evidence of Newton discussing antigravity in his works. One user references a past conversation suggesting that a phenomenon related to antigravity was renamed by another individual, but this does not confirm Newton's involvement. The original poster seeks specific references from Newton's "Philosophiæ Naturalis Principia Mathematica" regarding this topic. Overall, the consensus is that Newton did not address antigravity in his writings.

Hello to everyone

Did Newton prerdict that velocity played a role in antigravity or weight loss phenomenon?


Thank you

I'm confused. Are you referring to Isaac or Wayne?

AM :wink:
 
Perhaps you could provide some backgound information to help us help you. Do you have reason to believe that Newton had anything to say about antigravity? If he did I have never heard of it.

No he didnt.
 
I read a reply from J-Man to Petrus dated 1/5/03 reguarding the General theory on antigravity and J-Man tells Petrus that he has "renamed a phenomenon that has been predicted by Newton". That is why I was asking because I had never heard of such a thing my self. I own the book Philosophiae Natturalis Principa Mathematica, by Sir Isaac Newton and if I missed him talking antigravity I wanted to know what page it was on. Sorry for all of the confusion and thank you for your time and opinion.
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
