Universal Law of Gravitation: The universal law of gravitation states that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Kepler's Laws: Johannes Kepler formulated three laws that describe planetary motion under gravitational influence. These laws provide insights into how objects move in elliptical orbits around a central mass.
Escape Velocity:Escape velocity is the minimum velocity an object needs to escape from the gravitational pull of another celestial body. It depends on both the mass and radius of the body.
