Salá calcul ya force de gravité entre deux cubes soki cube moko na moko ezali na masse ya 2 kilos mpe ezali na 1 mètre distance.
 Nguya ya bozindisi kati ya biloko mibale ekoki kotangama na kosalelaka équation ya gravitation universelle, oyo elobi ete nguya ya bozindisi (F) kati ya biloko mibale oyo ezali na masse m1 na m2, oyo ekabwani na ntaka r, epesami na formule : F = G * . (m1 * m2) / r^2, esika G ezali constante gravitationnelle, ekokani na pene na 6,67430 × 10^-11 N m^2/kg^2. Soki to substituer ba valeurs oyo epesami na formule, tozali na : m1 = m2 = 2 kg (lokola ba cubes nionso mibale ezali na masse ya 2 kilos) r = 1 m (lokola ba cubes ezali na 1 mètre na kati) F = G * (m1 * m2) . / r^2 F = (6,67430 × 10^-11 N m^2/kg^2) * (2 kg * 2 kg) / (1 m)^2 F = (6,67430 × 10^-11 N m^2 /kg^2) * 4 kg^2 / 1 m^2 F ≈ 2.66972 × 10^-10 N Na yango, nguya ya bozindisi kati na ba cubes mibale ezali pene na 2,66972 × 10^-10 newtons.
