    Gravitational force = G · m₁ · m₂ / r²

    ' G ' is the 'universal gravitational constant, 6.673 x 10⁻¹¹ m³/kg-s²

    m₁ = 60 kg

    m₂ = 120 kg

    r = 5 m

    F = (6.673 x 10⁻¹¹ m³/kg-sec²) · (60 kg) · (120 kg) / (5m) ²

    F = (6.673 x 10⁻¹¹ · 60 · 120 / 25) · (m³ · kg · kg / kg · s² · m²)

    F = 1.922 x 10⁻⁸ (kg · m / s²)

    F = 1.922 x 10⁻⁸ Newton (about 0.0000000692 ounce of force)
