Question

importance of universal law of gravitation.
at least 4 points

Answer 1

The gravitational force is a force that attracts any objects with mass. You, right now, are pulling on every other object in the entire universe! This is called Newton's Universal Law of Gravitation.

Answer 2

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 $10^{-11}$

gravitational force is a long range force but it is the weakest force
