this is more of a physics question but how do i get the gravitational force of the earth and the moon?
Universal Gravitation Equation
The Universal Gravitation Equation is:
F = GMm/R2
where
F is the force of attraction between two objects in newtons (N)
G is the Universal Gravitational Constant = 6.674*10−11 N-m2/kg2
M and m are the masses of the two objects in kilograms (kg) (the moon and the earth)
R is the separation in meters (m) between the objects, as measured from their centers of mass (the moon and the earth)
