what is gravity?
Essentially, gravity is an attractive force between objects. Most people are familiar with gravity as the reason behind things staying on the Earth's surface, or "what goes up, must come down," but gravity actually has a much vaster significance. Gravity is responsible for the formation of our Earth and all other planets and for the movement of all heavenly bodies. It is gravity that makes our planet revolve around the Sun, and the Moon revolve around the Earth.
The idea of the Answers section at HubPages is that you ask a question and other people answer. You're now answering your own question. You should write a hub instead if you want to discuss gravity.
I'm sorry I'm new here that's why i don't know.
can i ask you a how can a answer the other hubs question??
In Einstein's thought experiment, he compared that gravity could just as much be acceleration. Some sort of inertia force or something like that. I don't really know the details but, hey, what he's saying does make sense.
Gravitation is a natural phenomenon by which physical bodies attract with a force proportional to their mass. In everyday life, gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence of the Earth, the Sun, and most of the macroscopic objects in the universe.
Earth attracts any thing towards it, that force is known as the gravity , g=9.8 m/s
also there is another equationG = m1m2/r*r
this is the force between two bodies have masses m1 and m2 and seperated by a distance r

I know you are going to answer 'gravity', but it is just the name of the phenomenon. The question is how(the mechanism) objects fall to the ground? How earth attract objects, that is far away?

Does anyone have a reasonable explanation as to why we can only see one side of the moon from earth?

At the risk of being eaten alive by the atheists, I'm curious what others think.Someone asked a question about free will here in the forums the other day, and it sent my mind on a tangent. I've always thought time was something that ran full circle. As if our reality was simply riding a ripple...

I've put this into the philosophy forum because I'm interested in what those who ponder the meaning of the cosmos would consider the ramifications of the answer to be.We talk of the Space-Time Continuum. We know the following:Cosmologists tell us it would be impossible to go back in time because...
