Gravitation is a fundamental force of nature that describes the attraction between two objects with mass. It is responsible for the motion of planets, stars, and galaxies.
The prerequisites for understanding gravitation include a basic understanding of Newton's laws of motion, knowledge of vector calculus, and an understanding of the concept of mass and its role in gravitational attraction.
The greater the mass of an object, the stronger its gravitational pull. This is why larger objects, such as planets, have a stronger gravitational force than smaller objects, such as rocks. Mass also affects the acceleration due to gravity, as described by Newton's second law of motion.
Yes, there is a difference. Gravitational force is the actual force of attraction between two objects with mass, while gravitational field is the region around an object where the force of gravity is exerted. The strength of the gravitational field is determined by the mass of the object creating it.
The theory of relativity, specifically Einstein's general theory of relativity, revolutionized our understanding of gravitation. It explains that gravity is not a force between masses, but rather a curvature of space and time caused by the presence of mass. This theory has been proven through various experiments and observations.
