Space time is a mathematical model that is fused into three dimensions of space and one dimension of time, which is considered as a four-dimensional manifold. The gravitational pull at a longer distance was well explained by Einstein’s theory of equivalence. The freely falling body is independent of its structure and internal compositions. The weak equivalence principle states that the laws of motion for freely falling particles are the same. Gravity is geometrical in nature and this theory is given by the strong equivalence principle. The strong equivalence principle is followed only if the size of the system is small, and the dynamical behaviour is not affected by the external environment. According to the strong equivalence, all the laws of nature in a uniform static gravitational field are the same. the gravitational pull from the Sun to the Earth.
The theory only explained the law of gravity at a distance i.e. Sir Isaac Newton had already found the law of gravity, which he explained in the behavior of the solar system. This force was the same as experienced by a person who was in non-inertial frame of reference. This was proposed by Albert Einstein when he first observed the force due to gravity, which was experienced by a person standing on a large object. The general relativity principle states that the equivalence principle is the equivalence of gravitational and inertial mass. Galileo’s work was carried forward by Isaac Newton. He showed that gravitational acceleration is same for all the objects. The work on gravitational theory was first done by Galileo Galilee. He is known as a theoretical physicist who developed the theory of relativity. If the mass of an object is doubled then the gravitational force is also doubled.Īlbert Einstein was born on 14 March in the year 1879, in Germany. The gravitational force is directly proportional to the mass of interacting objects and hence will attract at a greater force. Newton’s third law states that the force is dependent on the mass of the Earth. He said that the force caused by acceleration is due to the mass of the object. The equation of gravitational force is given as: He saw that the Sun and the Earth were attracted to each other because of the phenomenon of gravity. Sir Isaac Newton gave the idea of gravitational force when he first saw this phenomenon in the solar system. The first instance of gravity was first observed in the form of quantum gravity and gravitational singularity. It is approximately times weaker than strong interactions. Gravity is the weakest of the four fundamental interactions of physics. All the objects attract each other with a force of gravitational attraction. The Sun, Earth, and the stars are all attracted to each other because of gravitational force. It is a natural phenomenon which is applicable to everything around us. Gravitational force is the tendency of an object to attract another.
