definition of gravity ???????

[Alyoshya (nutjob)]

I just want to know if my way of explaining the gravity is correct or not.

 

Gravity can be explained as a mass attraction.

 

As the ( law/statement/hypothesis or whatever ) states .

[ "Every object in the universe is attracted towards each other" ]

 

Based on this law,

gravity is a mass level attraction exerted , by the heaviest body [(in accordance to the rest of the bodies that are present in that region)] and experienced by the bodies that satisfy both of the following conditions

1) It must falls under the influence OR efficient/effective range , of the mass

 

2) The body should be lighter than that of the body that attracts

 

[ Is this explanation correct & acceptable ???? ]

 

Or is there any other way to define/explain it ??????

 

[ LEAVING THAT ASIDE ]

I can't see how my hypothesis explains the ginormous gravitational force of the " black hole "

By my way of explanation the black hole must poses ginormous mass

 

"DOES IT ?"

 

And my explanation must also prove that the heaviest man in the room exerts a pulling force on the ppl and object that fall under his range ( ie. His mass's range )

 

"Well DOES HE ?"

 

But at the same time

 

I can't seem to understand the law I stated in the beginning of this topic

That is.

 

How even the lighter masses tend to exert some level of attraction on the masses that are heavier that it is.

 

Well...... I can see it doesn't hold a significant effect

And I can see this small force is getting canceled by the greater one.

 

But I can't see is

how it is able to / capable of exerting that (non significant) attractive force on the greater mass.

 

SOoooooo

 

HELP ME WITH THESE QUESTIONS ???????

Maybe you should first read up on Newton's Universal law of gravity.

Ya....... I probably should

The attraction of gravity is NOT mass its Energy and Momentum.

Care to clarify what momentun has to do with gravitational attraction?

Care to clarify what momentun has to do with gravitational attraction?

In general relativity it is the energy-momentum tensor that acts as the source of gravity. In Newtonian gravity you don't see this and only the mass is important.

Got it, thanks!
