What would cause the force of gravity acting between two objects to be four times greater?
If the mass of one or both objects were increased by a factor of four, the force of gravity between them would be four times greater. The force of gravity is directly proportional to the product of the masses of the two objects.
Are gravity and magnetism examples of contact forces?
No, gravity and magnetism are not examples of contact forces. Contact forces require direct physical contact between objects for interaction to occur, while gravity and magnetism can act at a distance without physical contact.
How does gravity cause massive collisions?
Gravity causes massive collisions by attracting objects with mass towards each other. When two massive objects are traveling towards each other due to gravitational pull, they can collide with great force, releasing a huge amount of energy. This process is seen in celestial bodies such as galaxies, stars, and planets.

How much does gravity weigh?
Mass itself doesn't actually change gravity (on a notable scale, unless their is a whole lot of mass, like a planet), but rather the amount of mass affects, how gravity will effect it. Technically, all objects have gravity, but most aren't noticeable. But, to answer the question mass does "change gravity" dramatically, for example if you have a human and a plant, obviously the plant has more mass, so the human is drawn to the plant, But, if you have to human next to each other their will be no noticeable gravitational pull, so clearly mass has a great effect on gravity.
Is Mars filled with gravity?
Filled with gravity? It does have gravity, just not as great as Earth's since it is smaller. The greater an object, the more gravity it has to pull objects close to it.
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.
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.
Why don't you feel the pull of gravity when you hold an open book?
because the mass of the 2 objects is to great
The force of gravity acting on an object is the objects what?
All mass attracts all other mass, thats a fact. The force between two independent masses depends on the total mass and the distance between them. The "cause" of gravity is subject to great debate, even today.
Why do lighter objects fly slower than heavier objects?
they have less mass. heavier objects have a great mass so it gets pulled down faster..... by a little thing called......gravity!
How are planets and sun are alike?
They tend to be round, spherical objects which are visible in space. They have great mass and their own gravity.
Is there gravity in outer space?
Yes, gravity exists in outer space. Gravity holds the moon in its orbit around the earth. It holds the earth in orbit around the sun. It holds the milky way galaxy together. It holds the local group of galaxies together. And the local group of galaxies might be a group of a string of galaxies held together by the great attractor.
What determines how great a force gravity will place upon an object?
-- The gravitational force is always a two-way thing. It acts between two objects, on the line between their centers. The force on each object attracts it toward the other one, and the forces on both objects are always equal. -- The strength of the force depends on ===> the product of the masses of the two objects. Bigger product = more force. ===> the distance between their centers. Bigger distance = less force.
How does the distance between objects affect the gravity them between?
The farther apart two objects are, the less the gravitational force between them. Gravity gets weaker with distance. To be specific, it decreases by the square of the distance. If you double the distance (multiply the distance by 2), the force of gravity is 1/22 or 1/4th as great as it was. If you triple the distance, the force is 1/32 or 1/9th as great, and so on.
Why does earth not have zero gravity?
Because it has great mass, subatomic particles, called gravitons, cause it to attract all objects near it
