2.1 The Law of Gravity
The law of gravity, formulated by Sir Isaac Newton, describes the universal force of attraction between objects with mass; Newton’s law of universal gravitation states that every point mass attracts every other point mass by a force acting along the line intersecting both points. The force is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This law is mathematically expressed as ( F = G rac{m_1 m_2}{r^2} ), where ( G ) is the gravitational constant. Albert Einstein later expanded upon this concept with his theory of general relativity, which describes gravity as the curvature of spacetime caused by mass and energy. Understanding gravity is essential for explaining phenomena such as planetary orbits, falling objects, and the behavior of galaxies, making it a cornerstone of both classical mechanics and modern astrophysics.
