constant of gravitation.
See under .
the factor relating force to mass and distance in Newton’s law of gravitation. It is a universal constant with the value 6.673 × 10–11 N m² kg–2 G
gravitational constant grav·i·ta·tion·al constant (grāv’ĭ-tā’shə-nəl)
The constant in Newton’s law of gravitation that yields the attractive force between two bodies when multiplied by the product of the masses of the two bodies and divided by the square of the distance between them. Also called newtonian constant of gravitation.
A constant relating the force of the gravitational attraction between two bodies to their masses and their distance from each other in Newton’s law of gravitation. The gravitational constant equals approximately 6.67259 × 10-11 newton square meters per square kilogram. Its symbol is G. See more at Newton’s law of gravitation.
noun, Physics. 1. the attractive effect, considered as extending throughout space, of matter on other matter. 2. the region surrounding an astronomical body in which the force of gravitation is strong. noun 1. the field of force surrounding a body of finite mass in which another body would experience an attractive force that is proportional […]
- Gravitational interaction
noun 1. an interaction between particles or bodies resulting from their mass. It is very weak and occurs at all distances See interaction (sense 2)
noun, Astronomy. 1. a heavy, dense body, as a galaxy, that lies along our line of sight to a more distant object, as a quasar, and whose gravitational field refracts the light of that object, splitting it into multiple images as seen from the earth. noun 1. (astronomy) a lenslike effect in which light rays […]
noun, Physics. 1. the mass of a body as measured by its gravitational attraction for other bodies. noun 1. the mass of a body determined by its response to the force of gravity Compare inertial mass
