Hi guys,
Just a small doubt is there anything like gravitational energy.
I was just wondering. I know about gravity as a force. But energy, i'm not sure. We quantize mass as its like same as energy. How does it apply to gravity?

How would you equate magnetism and electro-magnetism within this context of gravity?

Are they weighty subjects!And has attraction and repulsion got anything to do with it all?

Energy just is!


hope that helps.

the inner dot scalar product of a gravitational force and the distance traverse by an object where and when this force was applied to acquires gravitational energy in return. But the outer vector cross product of the same is that of planetary motion at constant uniform angular acceleration.

Why coun't I have said that-its so obvious?

Is there any equation for the gravitational energy in terms of 'mass' and 'distance'.

And what is the inner and outer scalar and vector product. Is it different from the normal scalar and vector product.

If Gravity is an energy, does it follow the law of conservation of energy??

This is Newton's law of universal gravitation. The vector form is a later version when vector analysis was created for solving scalar and vector products of vectors. See http://www.glenbrook.k12.il.us/GBSSC...les/u6l3c.html and http://www-solar.mcs.st-and.ac.uk/~a...als/node3.html

Thanks Antonio. That was gravity as a force. Well, I was talking of gravity as energy.
We have a photon which has energy hf. So like that is there any kind of energy associated with a graviton?

I've no idea dipayankar. I even have trouble visualizing gravity as energy. What do you think.

[dipayankar]

I somehow like Johns (everymans medium) idea that Gravity is a rection to the expansion of the three spatial dimensions into the time dimension..
