Is ower sun big enough to make a black hole?
No. The only mechanism by which black holes are known to form is the gravitational collapse of a star with a mass at least 20 times that of our Sun. All objects require some outward force to balance gravity. In main sequence stars, the outward flow of energy from the nuclear reactions in the core creates an outward pressure to balance gravity. Once the fuel is exhausted and the core collapses, there are two more forms of pressure which can halt collapse. First, electron degeneracy pressure, which can be thought of as a repulsion between electrons. Electron degeneracy pressure can support a body of up to approximately 1.4 times the mass of the Sun, and stars that end their life in this state are known as white dwarves. Second, neutron degeneracy pressure; repulsion between neutrons. We are less certain about the extent to which neutron degeneracy pressure can support a body against gravitational collapse, but we understand the limit to be somewhere around 2.5 times the mass of the Sun. Stars that end in this state become neutron stars. An object experiencing gravitational collapse which has a mass greater than can be supported by neutron degeneracy pressure will collapse into a black hole. Note, that it is not the entire star that collapses, merely the core. The outer envelope of the star is ejected as a planetary nebula in the case of lower mass stars, and in a supernova in the case of higher mass stars.
What is acceleration deu to gravity"g"?
Acceleration due to gravity "g" is produced by a gravitational force. This can be understood through Newton's law of gravitation: Law of Gravitation: F = (G * m1 * m2) / r^2 where, F is the gravitational force, G is the gravitational contraction number (used in the gravitational formula), m1 and m2 are the masses of two objects, r is the distance between two objects. It follows from this formula that the force of gravity is universal in relation to the velocity and distance between the two objects. "g" here stands for gravitational contraction number or gravitational contraction number of gravitational space (gravitational constant). Because its value is very small, the effect of gravity on the gravitational force is not very strong. It is resorted to by humans at almost all lengths and times. Acceleration of an object with the Earth by gravity "g" is a quantity of energy, which is very small in a single month's mass in a single time. It is important to note that "g" deals with the acceleration of the object relative to Earth, and does not focus on the overall acceleration.
What is the gravitational pull of objects called?
Gravitational attraction.
How does the gravitational force between 2 objects that have small masses compare to the gravitational force between large objects?
If the objects are the same distance apart (center to center), then the gravitational force between two less massive objects will be less than the gravitational force between two more massive objects.
Is there more gravitational force between objects with small masses or objects with large masses?
Objects of greater mass have more gravitational pull.
How does mass of objects affect gravitational force between objects?
The gravitational force is directly proportional to each of the masses.
What types of objects experience gravitational forces?
All objects on Earth experience gravitational force to a certain degree. Earth's atmosphere grants it's objects a great gravitational force.+++"All objects throughout the Universe experience gravitational force... " Not just on Earth. The Earth's orbit around the Sun is a function of the Earth's velocity and the Sun's gravity.The Earth's atmosphere does NOT "grant" any gravitational force of its objects (whatever those may be), but is itself subject to the gravity of the planet; hence both it still being here, and exerting a mean pressure of I Bar (by definition) or 100kPa at sea-level.
When is the gravitational force zero?
When you don't have gravitational interaction between objects.
What happens to the gravitational force between two objects reduced?
The gravitational force will get less if you move the objects further apart.
What increases when the gravitational forces increase?
the gravitational forces.Answer:As mass increases the gravitational force increases. Also, as the nearness of the objects increases the gravitational force increases, but this is usually thought of as the distance between the objects decreasing
What objects experience large gravitational forces?
Large dense objects, and the closest objects.
What gravitational force exerts on an object?
Gravitational force exerts an attraction on objects.
