$$F = Gm_1m_2/r^2$$
Where:
- F is the gravitational force in Newtons (N)
- G is the gravitational constant = 6.674 × 10^-11 N(m/kg)^2
- m1 is the mass of the first object in kilograms (kg)
- m2 is the mass of the second object in kilograms (kg)
- r is the distance between the centers of the two objects in meters (m)
In the case of the Earth, m1 is the mass of the Earth, which is approximately 5.972 × 10^24 kg.
