Because mass creates a field of space around it, much like an electrical charge creates a field of voltage potential around it. Because there is more “space” around and near the object, in a sense space is less dense the nearer you get to the object.
Why does mass create gravity?
To do that, we must look at the theories of scientists more recent than Einstein. According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons.
Is mass a force created by gravity?
In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity.
Can you have mass without gravity?
Yes, there will still be a mass because mass is the amount of matter in an object so there will always be matter in an object.
Why does mass not affect gravity?
"What are the factors that affect the acceleration due to gravity?" Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.
How does mass relate to gravity?
Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force). The gravitational force weakens rapidly with increasing distance between masses.
Does mass change with gravity?
Mass– the amount of matter than an object is made of. Mass does not change with gravity. Weight– the amount of gravity acting on (pulling down on) an object (or mass). Gravity– a natural force that pulls objects downward.
Does zero gravity exist?
No Zero Gravity Contrary to popular belief, there's no such thing as zero gravity. Weightlessness and zero gravity are two different things. The earth's gravity keeps the moon in orbit. And astronauts are generally much closer to earth than the moon is, which means that the earth's pull on them has to be much stronger.
Why space has no gravity?
On Earth, astronauts feel the force of gravity as weight, because Earth's surface prevents them from falling. In outer space, however, there is no ground to push against astronauts. As they orbit and fall toward Earth at the same rate as their spaceship, astronauts feel weightless, as if there were no gravity.
How does mass affect gravity?
So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.
