Is there such a thing as gravity or does the earth suck?

Answer 1

Yes, it sucks. And what with all the hurricanes we've been getting, I'd have to say that it both sucks, and blows.

Answer 2

There is such thing as gravity and the Earth does not suck.

Answer 3

Every planetary body, including the Earth, is surrounded by its own gravitational field, which exerts an attractive force on all objects. Assuming a spherically symmetrical planet (a reasonable approximation), the strength of this field at any given point is proportional to the planetary body's mass and inversely proportional to the square of the distance from the centre of the body.

The strength of the gravitational field is numerically equal to the acceleration of objects under its influence, and its value at the Earth's surface, denoted g, is approximately 9.8 m/s². This means that, ignoring air resistance, an object falling freely near the earth's surface increases in speed by 9.8 m/s (32 ft/s or 22 mi/h) for each second of its descent. Thus, an object starting from rest will attain a speed of 9.8 m/s (32 ft/s) after one second, 19.6 m/s (64 ft/s) after two seconds, and so on. According to Newton's 3rd Law, the Earth itself experiences an equal and opposite force to that acting on the falling object, meaning that the Earth also accelerates towards the object. However, because the mass of the Earth is huge, the acceleration of the Earth by this same force is negligible, when measured relative to the system's center of mass

Answer 4

Gravity is the result of the spin of the earth on its axis, and the orbit around the sun, and maybe the galactic spin adds to our gravity to. So if the earth suddenly stoped dead in its tracks, we would all just fly right off this planet of ours. Also look into newtons theory on gravity.

Answer 5

theres a such thing called gravity otherwise we wouldn't be able to stay on the ground off earth we would all be floating around

Answer 6

"Sucking" requires a difference in pressure, which has nothing to do with gravity. Adn if you want to be specific, if it were to "suck", it would do the opposite as gravity because space is pretty much a vacuum, and the inner core of the Earth has extremely high pressures.

Answer 7

The gravity of the dilemma is that even though the Earth doesn't suck many of its humans do.

Answer 8

Gravitation is a natural phenomenon by which all objects with mass attract each other. In everyday life, gravitation is most familiar as the agency that endows objects with weight. Gravitation is responsible for keeping the Earth and the other planets in their orbits around the Sun; for keeping the Moon in its orbit around the Earth; for the formation of tides; for convection (by which hot fluids rise); for heating the interiors of forming stars and planets to very high temperatures; and for various other phenomena that we observe. Gravitation is also the reason for the very existence of the Earth, the Sun, and most macroscopic objects in the universe; without it, matter would not have coalesced into these large masses and life, as we know it, would not exist.

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 most cases.

In scientific terminology gravitation and gravity are distinct. "Gravitation" is the attractive influence that all objects exert on each other, while "gravity" specifically refers to a force which all massive objects (objects with mass) are theorized to exert on each other to cause gravitation. Although these terms are interchangeable in everyday use, in theories other than Newton's, gravitation is caused by factors other than gravity. For example in general relativity, gravitation is due to spacetime curvatures which causes inertially moving objects to tend to accelerate towards each other. Another (discredited) example is Le Sage's theory of gravitation, in which massive objects are effectively pushed towards each other.

Answer 9

The only thing dumber than this question is the guy who answered it by saying gravity is caused by the earth spinning on it's axis

Answer 10

Because the Earth spins on its axis... the force from it spinning creates or affects other objects that's nearer to it !!.. Therefore that wobble creates a force/of fulling & pushing!?! So that movement & it's force has affects on other objects!! & the fact that a fe other large objects in space spins or rotates in the opposite direction of other objects/planets & moons so all those could create a friction/force that effect might be ``a`` reason for "gravity"!?! `'R"r,r`r.r'r`.'.-

Answer 11

Gravity is a theory, not a law. So, there is such a thing as gravity, but scientists are not able to prove it exists simply because you cannot see it. You can see it's outcome, but not the physical thing.
