Gravitational Force
Gravitational Force
Hello friends, in this blog you will get to know about gravitational force. This force acts among all particles of the universe. Its range is infinite. Gravitational force plays a very important role in wide events of the universe like formation of stars and galaxies and their development etc.
As you know there are four kinds
of forces in our nature- Gravitational force, electromagnetic force, weak
nuclear force and strong nuclear force. This is the universal force. Every particle
of nature feels the gravitational force. It is the weakest force of nature of
the nature but it affects the things which are far away. One more interesting
thing about gravitational force is that it is always attractive.
If you add up two things, you
will find the range of gravity higher. Suppose, the range of gravitational
force of the earth is R and another body has mass m[fig(1) & fig(2)]. So according to Newton’s law-
Now we can see, the range becomes greater after adding up the mass. You should notice that the force
You know, gravitons are the only
particles of the four others that are not detected yet. We study about it
according to theories.
You should know that the gravitational law of Newton has already been broken by Einstien’s general theory of relativity. But we study this law in our syllabus because even today this law works properly for general experiments.
I hope you may like the blog.
