How does gravity work ? Is it relative to the mass of an object?

Answer 1

Einstein's definition of gravity is the warping of space time by mass. Gravity isn't a force pulling on you, it's warped space pushing you toward the center of the mass. Of course the more mass the more space time is going to be warped.

Answer 2

Gravity has nothing to do with the spinning of the Earth.

Gravity is one of the 4 fundamental forces. The other three are electromagnetism, the strong nuclear force, and the weak nuclear force. The latter two are forces that we don't deal with directly.

All matter attracts other matter. The amount of attraction is proportional to mass and inversely proportional to the square of the distance between the objects. Basically, the bigger it is, the more it pulls. The further away it is, the less it pulls. Distance is a much bigger factor than mass though. Gravity is the weakest of the four forces. It may not seem that way due to the fact that Earth holds us here very well, but think of it this way: A simple refridgerator magnet can lift a paperclip away from all the gravitational pull of our massive Earth.

Answer 3

Gravitation is a phenomenon through which all objects attract each other. Modern physics describes gravitation using the general theory of relativity, but the much simpler Newton's law of universal gravitation provides an excellent approximation in many cases. Gravitation is the reason for the very existence of the Earth, the Sun, and every object in the universe; without it, matter would not have coalesced into masses and life would not exist. Gravitation is also responsible for keeping the Earth and the other planets in their orbits around the Sun; the Moon in its orbit around the Earth; the formation of tides; and various other natural phenomena that we observe.

it is the force with which we r bound to the earth

g=GM/R*R

g- gravitational force
G-gravitational constant
M-mass of earth
R-radius of the earth
yes it is relative to the mass

gravity increases at the poles as the R increases
gravity decreases at the equator as the R decreases

Answer 4

Gravity is a consequence of attraction between objects due to their mass. In Newtonian physics, the force due to gravity depends upon the product of the masses divided by the distance (squared) separating their centers of mass.

Answer 5

Yes. The more massive an object is, the more gravity it has. Also, the closer you are to that object, the stronger the gravitational field is.

Answer 6

gravity is caused by the earth spinning around.
