Gravitation

GRAVITATION
Gravitation- is a universal interaction between all bodies. If the interaction is weak and the object is moving at a speed much smaller than the speed of light in a vacuum, then Isaac Newton's law of universal gravitation is valid. In cases where the interaction is strong and the speed of the object is close to the speed of light in a vacuum, Albert Einstein's theory of general relativity correctly describes gravity.





 

Gravitation is one of the four fundamental interactions: electromagnetism, the strong interaction and the weak interaction, gravity.
Gravity depends on mass. period Rotational speed can create a centrifugal force that opposes gravity and makes things easier, but it is not gravity. Gravity is still 100% controlled by mass.
Gravity is best described in the general theory of relativity (proposed by Albert Einstein in 1915), which describes it not as a force of gravity, but as a curvature of space-time caused by the uneven distribution of mass and causing the masses to move along a geodesic path lines. The most extreme example of this curvature in space is a black hole, where nothing, not even light, can pass through the black hole's event horizon. [3] However, for most applications, gravity is best approximated by Newton's law of universal gravitation, which describes gravity as a force that causes any two objects to be attracted to each other, the magnitude of which is proportional to the product of their masses and the distance between them.
According to Newton's second law, a body of mass t moves with an acceleration a relative to the reference frame associated with the Earth under the influence of gravitational force.
