Universal Law of Gravitation: This law states that every object in the universe attracts every other object with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them.
Weight: Weight is the force experienced by an object due to gravity. It depends on both the mass of the object and the strength of gravity.
Escape Velocity:Escape velocity is the minimum velocity an object needs to escape from a planet or satellite's gravitational pull. It depends on both the mass of the planet/satellite and its radius.
