Question

what is the force of gravity

Answer 1

Gravitation, or gravity, is a natural phenomenon by which all physical bodies attract each other.
                                            F = (G x m1 x m2) / r2
Where:
F = force of gravity
G = gravitational constant
m1 = mass of the first object
m2 = mass of the second object
r = the separation between the two masses

Answer 2

The phenomenon by which all objects in the universe attract each other is called the force of gravity.
