everyone knows speed of light,speed of sound,speed of elec etc. what is speed of gravity.?

Answer 1

It is 9.8 m/sec , some they have made it 10 :)

Answer 2

Do you mean "how long does it take gravity to act on an object?" or something of that sort.

It's thought that gravity acts at the speed of light. It's also thought that gravity travels much the same way as light...in waves. This has yet to be proven however the facilities to test this theory by detecting gravitational waves have been built.

Concerning the other posts, the ACCELERATION of gravity, that is, how fast gravity causes a falling object to speed up, is 9.80 to 9.81 meters per second per second here on Earth and that is only very close to the surface.

Answer 3

The speed of gravity is the speed of light.

The speed of light is a bit of a misnomer. It is actually the speed at which all zero rest mass particles travel. And as the forces of nature are tansmitted by zero rest mass particles, it is the speed at which forces are transmitted. The photon (light) is actually the particle that transmits the electrostatic force.

What this means is that if - by magic - the sun vanished now, the earth would continue on its orbital path for about 8 minutes - the time it would take for the change in gravity to reach us.

Answer 4

Neat question, I believe we are effected by an objects gravity instantaneously, no matter where it is located within our known universe. Gravity would then be a property of matter that creates some type of unity or association with the rest of the universe that can not be understood with our present knowledge.

I believe this understanding will open the door to where we came from and a whole new type of physics allowing the possibility of time travel or dimension travel. Gravity provides the porthole to which our universe was born and all possibilities.

Answer 5

The force of gravity moves through space at the speed of light, supposedly, much as the speed of electric-magnetic forces. People believe that gravity is caused by particles called gravitons, and the speed of light is considered the maximum speed.

Speed of light: ~3.0*10^8 m/s

Answer 6

How can gravity have speed ? Only objects falling under the influence of gravity have speed. Gravity is a field which means that how far from its originating point will it effect the objects.

Answer 7

Black holes of various masses are thought to have sprung into existence within 1 second of the big bang, as elementary particles clumped together at extreme energies. But Einstein's theory of general relativity predicts the smallest of these "primordial" black holes should have already evaporated, through a quantum process called Hawking radiation.

But according to some alternative theories that attempt to unify gravity with quantum mechanics, such as string theory, small black holes could still exist. That is because these theories propose extra spatial dimensions, which alter the way gravity behaves on small scales.

Answer 8

As yo know that gravity is proportional to mass.
force of gravity between to celestial objetcs increases as the mass of the objects increases.

But gravity itself is not a an entity to which we can relate speed.
it actually accelerates the objects of smaller mass ino that of larger mass. But it can't accelerate the objects more than the speed of light.

Answer 9

Gravity does not have speed. however, it makes bodies within it to increase in speed or velocity. this acceleration is called the accceleration due to gravity and varies according to the lattitude. average is 9.8m/s sq

Answer 10

Gravity is not speed. It is the rate of change of speed
say - m/s . s

Answer 11

Hey, gravity has no speed of its own. it pulls objects towards itself and produces an acceration of 9.8 m/s square.
