write two importance of universal law of gravitation
Answers
Answer:
The prediction about solar and lunar eclipses, made on the basis of this law came out to be very true. Importance of Universal Law of Gravitation. The gravitational force of earth ties the terrestrial objects to the earth. This law explains the attractive force between any two objects having a mass. The formation of tides in the ocean is due to the force of attraction between the moon and ocean water.
Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The publication of the theory has become known as the "first great unification", as it marked the unification of the previously described phenomena of gravity on Earth with known astronomical behaviors.
universal law of gravitation has a lot of importance
-------------------------------------------------
Newton's law of universal gravitation states that a particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers

1)with the help of this we can understand the force experience by various planets , stars with each other
2)we can understand how and why the planets revolve around the sun and how satellite revolved around the planets
3)it explains how the planets are held by the sun and why don't they fall on sun
4)it can also explain how is tided formed of earth , it can be due to the gravitational forces of sun moon etc as there will be low tides on no moon day and high tides on new moon day
5)it can also explain how far the gravitational force exists between the bodies in the universe
6)gravity in different planets is different and there is a universal gravitational constant whose values is 6.674 x
gravitational force is a long range force but it is the weakest force
