The law of universal gravitation states that any two objects in the universe attract each other with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Example 1
Determine the gravitational force if two masses are 30kg and 50kg separated by a distance 4m.
G = 6.67259 x 10–11 N m2/kg2.
It’s a general Physics law derived from the observations by Isaac Newton. In modern language, the law states: every point mass attracts another single point mass by a force pointing along the line intersecting both the ends.
