Why are all objects pulled toward the Earth?
All objects are pulled toward the Earth due to the force of gravity. Gravity is a fundamental force of attraction that exists between objects with mass, and the larger an object's mass, the stronger its gravitational pull. The Earth's mass is large enough to exert a gravitational force on all nearby objects, causing them to be pulled towards its center.
Do rocks have gravity?
No, rocks do not have gravity. Gravity is a fundamental force that exists between all objects with mass, including rocks. Rocks are subject to the force of gravity, just like any other object on Earth.
Why doesnt the mass of most object cause a force large enough to move object toward each other?
Most objects have a force of gravity acting on them that is proportional to their mass and the distance between them. If objects are far apart or have small masses, the force of gravity might not be strong enough to overcome other forces acting on them, like electromagnetic forces or internal forces within the objects themselves. This is why we don't see everyday objects being pulled towards each other due to their masses.
What do you call the force that is pulling on everything in the world?
You are probably referring to gravity. It pulls us towards the Earth and keeps our feet planted on the ground. Bigger objects like the Earth have enough gravity to really affect things. But something as small as a mountain can also exert a measurable gravitational force. So can a large Building.
What is the difference between an objects that float and the objects thasink in water?
Objects that float in water are less dense than water, so they displace enough water to counteract the force of gravity pulling them down. Objects that sink are denser than water and displace less water than their weight, causing them to be pulled down by gravity.
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.
Does Saturn's ring has gravity?
Yes, Saturn's rings do have some gravity, but it is very weak compared to the gravity of larger objects like planets and moons. The gravity from Saturn's rings is not significant enough to affect spacecraft or other objects passing through the ring system.
How does the distance between two objects affect the strength of the gravitation between them?
In Newtonian gravity (which is good enough for most purposes) the force scales inversely with the square of the distance. So moving them two times as far apart results in the force being four times as weak.
The weight of an object is based on what?
Its mass and the gravity of the objects that are close enough to it to have a great effect on it.
What exists between any two objects that have mass?
Any two objects with mass will be attracted to each other by gravity, which is a force that arises purely from mass. Any mass is possessed of gravity, and any two masses will be drawn toward each other by this force. But note that gravity isn't strong enough to cause, say, a rock to be attracted to a brick wall. They are attracted to each other by their mutual gravity, but that mutual gravity cannot overcome the other forces acting on them. The gravitational forces acting in this case are very small when we look at the "big picture" here.
Why are all objects pulled toward the Earth?
All objects are pulled toward the Earth due to the force of gravity. Gravity is a fundamental force of attraction that exists between objects with mass, and the larger an object's mass, the stronger its gravitational pull. The Earth's mass is large enough to exert a gravitational force on all nearby objects, causing them to be pulled towards its center.
Why is earth the only planet with gravity?
All objects with mass have gravity, so all planets have gravity. However, the strength of gravity depends on the mass of the planet. Earth's gravity is strong enough to hold objects to its surface, which is why we feel it as weight.
Do rocks have gravity?
No, rocks do not have gravity. Gravity is a fundamental force that exists between all objects with mass, including rocks. Rocks are subject to the force of gravity, just like any other object on Earth.
How big does an object have to be in order for it to have enough gravity to attract?
All objects with mass have gravitational attraction

Why does the moon have lees gravity?
The force of gravity between two masses depends on the product of the masses. So if either of the masses is reduced, the force between them is reduced. The Earth has about 80 times as much mass as the moon has. So the force of gravity between the Earth and any object on it is going to be more than the force of gravity between the moon and the same object when the object is on the moon. The distance between the two objects is also involved in determining the force of gravity between them, but the above discussion of the mass is enough to answer the question.
How does gravity effect the stars?
Please check the difference between the words "affect" and "effect". In this case, it should be "affect". Gravity keeps the stars together in the first place. It compresses them so much that they become hot and dense in their cores; enough so to start nuclear fusion.
