What is a gravitational field?
Gravity is the power of attraction between all masses. Although gravity is said to be developed by all that has matter, only those objects with very large mass actually affect anything close to them. The gravitational field is an area around the body that develops gravitational move. It can be defined as a gravitational force perceived by the unit located at the point in the space.
Gravity has three very important effects. First it accelerates it all. On Earth is acceleration due to gravity 9.8 meters per second to the other. This means that no matter what falls towards the ground, it will do the same acceleration if the resistance to air is not taken.
Second, gravity gives all the weight. Weight is a gravitational force that pulls something towards the ground. Weight and weight are not the same and the weight is used to determine the weight of something. The weight of the object is always the same, but its weight may change on the basis of the Strength gravitational field. For example, the weight of the object would be the same on the moon asOn the ground, but its weight would be different because of various gravitational forces.
Finally, gravity keeps all objects in the solar system in its orbit. The orbit is caused by the equilibrium movement of the object and the gravitational force that pulled it in. For example, the Earth's orbit around the Sun is caused by the forward movement of Earth and the gravitational pull of the Sun. The same happens with the moon around Earth.
The closer object is to the other, the stronger the gravitational field. In the solar system, planets have closer to the sun, much more powerful for them. To face this attraction, they must move in the sun much faster. The gravitational field decreases very quickly with distance.
The size of the gravitational force monitors an inverse square relationship. If the gravity of the building was measured and then moved twice as far from the large object causing gravitational field, GravItalifies would be reduced by a factor of four. If moved three times away, the gravitational force would be reduced by a factor of nine or a square of three. The opposite can be said whether the building has been moved closer, with the exception of gravity, gravity would increase instead of reducing.
