Universal Law of Gravitation
- The only form of the law that is symmetric in the two masses (mass of sun and mass of planet) is:
- This form of the law is universal.
- Newton’s law of gravity: There is an attractive force obeying the above law between every pair of masses in the universe. The constant G is universal and applies to all masses in the universe.
Where M and m are the masses of any two bodies, R is the distance between them and G is a universal constant!
