The gravitational force tugging between two bodies depends on how massive each one is and how far apart the two lie, according toNASA Glenn Research Center. Even as the center of theEarthis pulling you toward it (keeping you firmly lodged on the ground), your center of mass is pulling bac...
G is the universal gravitational constant. m1is the first body's mass. m2is the second body's mass. r is the distance between the two bodies. Therefore, the gravitational force seems to be the universal attractive force that exists across all stuff....
