    Answer:

Gravity is the force of attraction between two objects. Mathematically, it is expressed by Newton's Law of Universal Gravitation which states that

F = G *m1*m2/r^2

where G is the Universal gravitational constant, m1 is the mass of object 1, m2 is the mass of object 2, and r is the distance between the centers of gravity for both objects.
