State Newton's law of gravitation. What is the difference between:
Gravity and gravitation

उत्तर
Newton law of gravitation is that every object in the universe attracts every other object with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Gravity is the force of attraction between the object and the earth whereas gravitation refers to the force of attraction that exists between any two bodies that possess mass.
