Glossary term: Gravitational Constant

Description: The gravitational constant is one of the most important constants of the Universe. It was first derived by Isaac Newton. It is part of Newton's law of gravitational force, that shows that all particles with a mass attract every other particle (that also has a mass) with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the squared distance between the objects. The value of the gravitational constant has been measured through experiments to be 6.67 × 10⁻¹¹ cubic meters per kilogram per seconds squared (m³ kg⁻¹ s⁻²).
