define gravity?

Question

i dont think gravity is megnetic or things that stay on the north will fly off if mooved to the southern hemispere. is gravity even a enegry? maybe its opposite or enegry? this might have somthing to do with electircty going to ground?

your all answering by saying the effects of gravity i understand alot of that! what causes mass to attract? im thinking that mass is pushed to geather rather then attracted to eachother

the effect or the perportions of gravity strength to mass size

Answer 1

As previous answerers have said, gravity is a force (that is different than an "energy"). The reason they define gravity by its effects is that it's challenging to say what the cause is. Albert Einstein said it was a geometric quality due to the space-time continuum being curved in volumes containing matter.

Answer 2

ravity Website Gravity is a force of attraction only between bodies that have mass. The word 'gravity' comes from the Latin word "gravitas", meaning 'weight'. The force of gravity that one body exerts on another can be expressed as:
G * m1 * m2
Fgravity = ____________ (1)

r2




F = Force of gravity experienced by bodies. m1 = mass of body.
G = Gravitational constant , 6.6726 * 10-11 m3 kg-1 s-2. m2 = mass of second body.
r = radius of body.



From this an important equation for finding the force of gravity on an object e.g. planet.
Newton's second law states that:

F = m * a. (2)


If you substitute the 'F' in equation 1 with 'm * a' in equation 2, you will get:
G * m1 * m2
m * a = ____________ (3)

r2


Divide both sides by m and you will get:


G * m
a = _________ (4)

r2


At a 90 degree angle:
a = g (5)

So the new formula is:


G * m
g = _________ (6)

r2

Knowing the gravitational constant, the mass of the Earth, and your distance
from the centre of the Earth, you can work out the gravity of Earth.
Please note: Gravity is measured in Newtons(N) or kg m s-1.

Answer 3

Gravity is an attractive force between any two masses, proportional to the product of the inertial masses and inversely proportional to the square of the distance between them. With the boiler plate out of the way, we can look at the rest of your question. Gravity has no connection with magnetism or electricity. It is not itself an energy, although objects in a gravitational field have an energy because they are there.

Answer 4

Gravity is an effect caused by matter and is considered the weakest of the interactive forces between objects, but the effect is cumulative and even "dark matter" and EM radiation from dark body emissions to gamma rays are subject to its influence.
One model is to picture spacetime as a plane of streched stocking fabric, and our solar system as a bunch of ball bearings of varying sizes arranged in concentric orbital paths aroung a cue ball, the sun. It's the largest and heaviest, so it makes the fabric sag the most. Each of the planets rides in a groove around the center, moving too fast to be pulled in but too slow to escape.

Answer 5

Gravity is most often expressed as the attraction of one object to another object. This phenomenon has been expressed by many people in many ways yeat it has never been completely explained well. Gravity is one of those great mind twisters. This is my thought on gravity. The attraction of one body of matter to another body of matter, caused by the sine frequency of electrons vibration with-in the two bodies of matter. The voilate nature of the movements of these two bodies thru space is thus also affected by the forces of the universe acting on the matter in preportion to the size,speed and density of the matter itself. Each object is thus composed of elements that are in fact singing a song because of the vibration of the electrons with in the matter itself. The resultant attraction is a result of the sine waves being reflective from one object to the other and creating attraction between the surface of the two objects. This force is actually a attraction to the voids in the matter and not the matter itself. Thus we always have attraction of matter to the voids and folds of empty space and not the space that matter is actually in. This in congunction with the known understanding of the conduct of black holes could be considered the actual working of gravity. Newton might disagree. Nobody liked him anyway.

Answer 6

definite, definite, i'm particular all human beings right here has heard those arguments 1000's of time earlier. I easily have. in simple terms because of the fact which you *choose* to have self assurance some thing would not make it authentic. individually, as an existentialist deist, i've got not got self assurance there grow to be ever any plan, nor do i've got self assurance that there is any rationalization why we are right here. we are maximum suitable here. that is all. Then we die. that is it. so a techniques as a a author is going, i'm easily keen to purchase into that, yet i don't think of he cares to any extent further for us than he does the rest in the universe, which includes Mars or a speck of airborne dirt and dust. we are in simple terms not that distinctive... in simple terms a organic and organic anomaly or aberration. possibly i've got grow to be extra of a Materialist (and, oh how I used to hate Materialists!) in my previous age, yet i hit upon myself figuring out extra as an agnostic (or perhaps atheist) at the instant than the rest.

Answer 7

uhh.. gravity is nothing you said. Gravity is the force which pulls down matter towards the core of the earth which means if you dig a never ending tunnel from one side of the earth to the other and fall from it, you will be sucked in and soon you will be trapped in the center of the earth. it has nothing to do with electricity.

Answer 8

Each particle of matter attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Simplified: the larger something is, and the closer it is, the more it tries to draw other things to it.

North and South poles and electricity all deal with magnetism which is a different force.

Because the Gravity of the earth is open
