Is it true that Gravity exists between two objects but only when they're close enough to affect each other?
Not quite. Gravity can act at any distance. However, in practice, when the distance between the objects is great, the force of gravity may become insignificant.
Potential energy only exists?
between two objects
What is the force of attraction between two objects?
Gravity is the force of attraction between any tow objects. All objects have it and it's proportional to the mass of the objects and inversely proportional to the square of the distance between them.Strictly speaking, gravity only exists between two objects with mass, but since every (known) object has at least a relativistic mass, it works out to more or less the same thing.On the other hand, looking at the bigger picture . . . No mass ? No problem !You may substitute the mass of each object into the customary formula . . .F = G M1 M2 / R2and the result of the formula is the correct force, whether or not both objects have mass.
Is gravity a motion?
The pull of gravity between two objects depends on more than just the objects. Gravity's effect also depends on the distance between the objects. objects that are closer together have a greater attraction between them. The attraction is weaker when they are farther apart. Gravity exists wherever there is mass, such as in stars and planets.The gravity of each of these objects affects other objects in space.Earth's gravity, for example, reaches millions and millions of kilometers into space.It grows weaker the farther away from Earth you get. Recall that because the moon is less massive than Earth, an astronaut standing on the moon weighs only one-sixth as much as on Earth.The astronaut's weight would change between Earth and the moon.The effect of Earth's gravity becomes less as the distance from Earth increases.
Does gravity affect all objects in the same way?
Yes. The gravitational force between objects always depends only on their masses and the distance between them.
Is gravity exists only on earth?
Gravity exists between any objects with mass. The moon is 1/6 the size of earth therefore 1/6 the gravity Imagine you weighed 180 lbs on the moon you would weight 30lbs but the space suit and breathing euipment is so heavy that even on the moon you would still not be able to jump too far...lol
Does gravity acts on some objects only?
Gravity acts similarly on all objects.
What is the difference between gravity and anti gravity?
gravity is something that holds you down, anti-gravity is when you have no weight. Or to say it another way -- Gravity is real it exists in this universe. anti-gravity is fictitious it only exists in the imagination. Edit: Gravity is the universal attraction between massive objects. As postulated by Einstein it is a positive warpage of space-time by energy densities (recall mass / energy equivalency). Anti-gravity would be just the opposite; a negative warpage of space-time brought on by an energy density less than zero. This negative "mass" would appear to be repulsive to ordinary bodies.
What factors affect the amount of gravity between two celestial objects in space?
Not only in space - gravity is universal. The force of gravity is affected by the distance, and by the masses involved.
How gravity affects different types of objects?
gravity affects all object in the same way, as a gravitation attraction between two objects. the only changing factor between objects is the objects mass. the larger the mass, the more gravity acts on it. the equation for gravity of any two given objects is g = Gm1m2/r^2 that is to say that the gravitational force between two objects of mass 1 and mass 2 is equal to their masses multiplyed by eachother and the gravitational constant G over their distance apart squared. the further two objects are from eachother, the weaker the force is between them.
When the only force affecting an objects is gravity that objects is in?
Freefall this means the objects is falling through the air while gravity is pulling.
What fraction of the earth's gravity exists on the moon?
Gravity on the moon has exactly the same characteristics and behavior as it has on Earth and everywhere else. It causes a pair of forces between any two objects, that are proportional to the product of the objects' masses and inversely proportional to the square of the distance between their centers. Because of the moon's much smaller mass, the force between the moon and an object on its surface is only about 16% as strong as the force between the Earth and the same object when the object is on the Earth's surface.
