To make a grand unified theory "complete", does it have to involve gravity? If gravity is more of a warp of space-time, and less of an actual force, then do we already have a grand unified theory (since we have combined the other 3 forces), or do we NEED gravity to be a force to have a GUT.
So does this "back momentum" explain why someone with more muscle would punch harder, as they would be able to put more back momentum into their swing?
Just wondering...
If the interactions between fermions are the emittance of a boson (from what I understand from the grand design book by stephen hawking) then when you punch someone, is it just high levels of bosons being emmited and clashing or are the actual boson particles colliding?
The law I am talking about is F=K* (qa*qb / r2) I know the values of all but I have a question on the q's which represent the electrical charges...
If the charge is +2/3 do I plug in the fraction 2/3 in the q's spot? is this the numerical number I use? PLEASE HELP!
Yes I got it! thanks everyone again for the help! soo excited i might just go measure the amount of Newtons I am putting on objects in my room because I am so bored:} thanks again!
So (just to make shure I am correct) I would:
1) find all variables
2) multiply the mass of the two objects I am using/comparing
3) divide this by the distance squared
4) multiply this by 6.67428*10^-11
is this right?
DrGreg, jtbell, and tiny tim. Thank you so much I think I am starting to understand this! hopefully tonight will be my first calculations using Newtons universal gravitational constant! thanks so much everyone
so if I have two objects, one 100 kilograms and another 75, they are both 1 meter by one meter by one meter and are spaced 5 meters from each other what is the gravitational pull/attraction between them
Okay so on your first answer/post (something like "It would be G times 100 times 75 divided by the distance squared" what number would you replace G with? What is the 'final' answer? Thanks again
