Science: one of the army of our country

⚔️🔬 Science 🔬⚔️         The importance of science is well known today. Science is not just limited branch, it is very wide branch and extend study of the basics of science makes a new branch of science. For example, Biology is branch in which the study of living being occurred,  Chemistry the study of chemical, Microbiology the study of microorganisms, cell biology the study of all types of cell....etc....etc. But science does not seem to be as important as it should be. Now people understand that there is no alternative without science. Every one know that the science is a great career field, this is also a good education field, that's all there is to it. Still, we can say that ' Science is the one of the army of our country '. What is this nonsense....... How is that........ So let to prove this sentence, with evidence.... At first I would like to say that, we can't imagine the world without Science, because Science has given us so much

Law of Gravitation

💫Newton's law of gravitation ðŸ’«

Sir Isaac Newton defined what is gravitation, how is work and all concept by the law , this law of Newton is known as 'law of gravitation'.
The Gravitation law, defined some terms and one gravitational constant.


#Law ÷.                                                                             
"Every particle of matter attracts every other particle of matter with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them"

Formula of Gravitational Force

Where,
          'G' is a constant which is known as "Universal Gravitational Constant ".

         The gravitational force between two particles act along the line joining the two particles and they form an action-reaction pair . The force exerted by first particle on the second is equal and opposite to the force exerted by the second particle on the first .


*The value of the G (univarsal gravitational constant) is 6.673×10 -11 Nm2/kg2.

In this law sir Isaac Newton, prapose the gravitational law which gives relationship force between two particular matter or body's. here, the value of G is fixed and the matter or body mass is changes. After successfully calculation we get the exact value of gravitational force between this two body.
All the planets revolving around the sun and some moons are revolving around the planets etc like object stable due to the gravitational force, this gravitation and it's force introduced by sir Isaac Newton to the world .

Concepts of atom

In Last article We Define  Atom ,  Molecules  & Nuclei.  And the molecule    Atom and atomic concept is the very interesting part and it's not just interesting but important part for chemistry, physics.    Atom is considered as the basic and fundamental unit of the molecule or elements.    Atom is the important back bone of the chemistry, because no one any chemical compound is made up of without atom. Atom is the basic , fundamental and functional unit of the elements is not wrong.     Atomic model and atomic concept of the atom, Scientists gives verious information and the reality of the atom. For the extra and proper information, some scientists like J.J. thomason, John Dalton, and Rutherford gives the atomic theory, due to which the concept of atom for understanding is very easy. Before the atomic theory, we start the concept related to atom.                *  The Concept Related to Atom * In 1808 , John Dalton performed an his experiment and prove that

Units, fundamental quantities and derived quantities.

What mean by Units......? Unit is the basic part of the measurement, because without unit we don not measured anything. Unit:- The reference standard used for the measurement of a physical quantity is called a Unit. System of units:- C.G.S. M.K.S. F.P.S. S.I. units :-            Use of different system of units became very inconvenient for exchanging scientist information between different parts of the world.     Hence, in October 1960 at the Eleventh International General Conference of weights and measures, in Paris, a common system of units called  "System International d' Units"  was accepted.         This system of units called S.I. units consistent of seven fundamental units, two supplementary units and large number of derived units.      Units are classified into two  groups    F undamental units  and  Derived units . The seven basic physical quantities: Length, mass, time, temperature, electric current, lumino

COVID19 : A blessing or A curse

COVID-19 The novel corona or COVID-19 today all world worry about this.  What you need to know about the Corona virus pandemic. What is Corona virus ? People know about Corona virus . the biggest health club and organization like WHO and etc. plays an important role by getting awareness program, scientists and researchers work on Corona virus for getting more information about structure, shape, genetic material and all this is important for making drugs against the corona virus. But at the time of present it's not possible. All countries are contributing to the fight against novel corona virus. Everyone knows how dangerous corona is !!!!! But the truth is something different .  So let's start with my question...... Is Corona really dangerous ???? Yes, is dangerous for human and sometimes animals. Today in the world almost 247 thousands peoples are death due to the corona virus and this chain continues. If you think from the other side...... Corona
