All objects in the universe attract each other. The magnitude of the gravitational force between two objects is directly proportional to their (product of mass)? Inversely proportional to their (square of distance)? This is universal gravitation. Law. Its formula is (F=GMm/r^2)? In the formula, the gravitational constant G= (6.67259×10^(-11) N?m^2/kg^2)? The first one to measure this constant more accurately is a (British) physicist (Cavendish)
