Why does gravity cause objects to fall towards the Earth?

Answer 1

becoz of gravitational pull

Answer 2

Gravity causes attraction between any two objects. They move towards each other but the earth is so massive that you don't notice it's moving towards the other object. All you notice is the object falling into the earth.

Addendum: Gravity bends space. Think of space as a mattress and the earth as a bowling ball on the mattress. Now if you put a golf ball on the mattress near the bowling ball, it accelerates towards the ball until it impacts. Same thing with an object falling into the earth. If you roll the golf ball along the mattress, its path will curve with the curvature of the mattress, much like a comet's path curves around the sun with the curvature in space.

Answer 3

The standard formula for gravity is:

Gravitational force = (G * m1 * m2) / (d2)
where G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force, and d is the distance between the centers of gravity of the two masses.

G has the value of 6.67 x 10E-8 dyne * cm2/gm2. That means that if you put two 1-gram objects 1 centimeter apart from one another, they will attract each other with the force of 6.67 x 10E-8 dyne. A dyne is equal to about 0.001 gram weight, meaning that if you have a dyne of force available, it can lift 0.001 grams in Earth's gravitational field. So 6.67 x 10E-8 dyne is a miniscule force. When you deal with massive bodies like the Earth, however, which has a mass of 6E+24 kilograms, it adds up to a rather powerful force. It is also interesting to think about the fact that every atom attracts every other atom in the universe in some small way!

Answer 4

no one actually knows... Newton supposed it was a force but clearly stated that he did not know exactly why...

Other scientists also have suggested reasons

Einstein suggested it was to do with how objects bend the space-time continuum...


Quantum Physics has also suggested that there are things called gravitons which cause gravity, in much the same way photons cause light...

What we do know is that Newtons laws, both of motion and gravity do not work when considering extremes such as the approaching the speed of light or the gravitational effects of black holes...

as such einstein's theories, which are based on the principles of light and space and time etc, work much better...

bit confusing, but the short answer is...

no on actually knows!!

And since it has been mentioned... it is, in point of fact, not that powerful a force... it is in fact the weakest of the four natural "forces" which are electromagnetic forces, weak nuclear forces, strong nuclear force, and the weakest of them all gravitational nuclear forces... it is the far reaching qualities of gravity which form the misconception of it being a "strong" force...

That said however... I believe it is suggested that black holes can rip attoms apart... so i guess it all depends on the density of the body in question...

Answer 5

Since the force of gravity is directed toward the center of earth.

Answer 6

Gravity causes objects to fall towards the earth...........
This is all i knew never tried to go in depth in it ,,,,,,
But It is a force which was also observed by Newton...

Answer 7

Mass accelerates toward a large solar mass, as our planet, because of the energy contained within the mass. Were our planet to have no heat energy within it, then our planet would have no gravitational field. Were the energy within our planet to increase, then the gravitational field would increase. The equation explaining this force is found in, c2 = E/m. This shows that as the energy or mass change, the c2 value also changes.

The force of gravity attracts not only the mass of a body into that of a sphere, it also attracts the energy within that mass toward its center. Were it not for the beneficial drawing of the heat energy within our planet toward its center, our planet would be almost the same temperature throughout.

Then there is the unusual aspect of what this force does in the very center of our planet. Were you to determine the acceleration value of a mass 0.716 miles from the very center of our planet, you would find that that mass would be accelerating beyond the speed of light in one second. Mass cannot accelerate beyond the speed of light and remain mass. In our sun, this distance is 400 miles from its core point. What do you think this means?

There is a writing "Time, Energy, and Gravity" at http://360.yahoo.com/noddarc that is very easy to understand.

Answer 8

ok, lets start up by technique of taking the Jupiter state of affairs out of the photo. A jupiter sized merchandise will by no skill have the same mass as a marble. they are going to fall on the same price. 9.8 M-2d squared is acceleration, hence squared. once you're one hundred% suited in convey in the each and each merchandise has pull of its personal as remember attracts remember you may want to opt to apply a ratio formulation to calculate the pull the marble of bowling ball might want to have on earth it really is so rather minute there might want to opt to be 1x X to the adverse one hundred,000th power or some ridiculous ratio so it truly is really insignificant. Your bringing this into the equation is sweet enter and the form of international perception will instruct sensible in any situation the position the gadgets are more effective similar in length. That line of wondering is mandatory in aerospace technologies as gadgets passing one yet another effect tangents and procedures-set. save up the international idea procedures.

Answer 9

according to newton: (between every two objects in the universe there is an attraction force)

if one of the two objects is extremely big compared to the other, then the bigger attration force of the bigger one will attract the smaller one
thats why the earth pull us down (gravity) becouse we r too small compared to it, so its attraction force to us is too big, so it attracts us
also the sun do the same to the earth & the other planets, the sun is too big compared to these planets so it attract them

i hope u got ur point from my explanation

Answer 10

because it's not anti gravity
