Can anyone tell me that why we take r square instead of r?
homeomorphic said:A linear force law also produces elliptical orbits, but then the Sun would have to be at the center of the ellipses,
Newton's Law of Universal Gravitation is a physical law that describes the force of gravity between two objects with mass. It states that every object in the universe attracts every other object with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Isaac Newton discovered and published the Law of Universal Gravitation in his famous work, Principia Mathematica, in 1687. This law is one of the three laws of motion that form the basis of classical mechanics.
Newton's Law of Universal Gravitation is a fundamental law of physics that explains the force of gravity between objects. It is closely related to the laws of motion, as it is based on the principles of mass, acceleration, and force. It also plays a crucial role in understanding the motion of celestial bodies and the structure of the universe.
The strength of gravitational force between two objects is affected by two factors: the masses of the objects and the distance between them. As the masses of the objects increase, the force of gravity between them increases. On the other hand, as the distance between the objects increases, the force of gravity decreases.
Yes, Newton's Law of Universal Gravitation is still relevant today and is widely used in various fields of science and engineering. While it has been superseded by Einstein's theory of general relativity in certain situations, Newton's law is still accurate for most everyday applications and remains an essential concept in our understanding of the physical world.
