What is the Universal Law of Gravitation? Obtain a Mathematical equation for it. Also, give two points highlighting its importance.
Newton's universal law of gravitation states that when two body are separated by a distance r, then both attract each other with a force which is directly proportional to the product of their masses (m1 and m2) and inversely proportional to the square of distance between them (r). This force is termed as gravitational force. Mathematically, gravitation force is given by F=r2Gm1m2 where G is gravitational constant
