"Gravitational Force is an attraction between two bodies by the virtue of their mass. The force of attraction between two point masses is , where m1 and m2 are the masses of the particles and r is the distance between them. G is a universal constant having the value 6.67 \u00D7 10-11 Nm2kg-2."@en . . "Gravitational Force"@en . . . . . "Gravitational Force is an attraction between two bodies by the virtue of their mass.
