Science is present everywhere around us. Being the essential element of life, the basic knowledge of Science is imperative for every individual. Science is based on laws, theories, facts, research and hypotheses. In other words, we sometimes refer to science as the way of pursuing knowledge and not merely knowledge. Deeply associated with Science are the scientific laws that are derived by continuous experiments and observations on a particular subject. As it forms one of the major parts of learning Science, it is essential to know about the Important Scientific Laws. So, in this article, let us discuss all about the Important Scientific Laws. Also, at the end of the section, get to download a free PDF of the list of all important scientific laws also.
What is a Scientific Law ?
To begin with, scientific laws or simply the laws of science are mere statements that are deduced by continuous and repeated experiments as well as observations which are used commonly to chronicle or foresee a natural situation. The term law is of broad spectrum i.e, used in physics, chemistry and biology alike. Usually scientists use data to develop laws. However, it may or may not be based on empirical evidence.

Are Scientific Laws and Theories the Same ?
No, Scientific Laws are different from Scientific Theories.
Scientific Laws are different from Scientific Theories in the sense that laws are narrower than theories. While a law tends to explain only what happens when two forces meet, scientific theories do tell us much more. A scientific theory explains the “What” and “How” of a natural occurrence.
However, both scientific laws and scientific theories shall be considered as facts in common. Meanwhile, with ample evidence, a law or a theory can be falsified.

Important Scientific Laws & Statements
There are many important scientific laws that explain to us the existence of some of the major phenomena. Out of the list mentioned above, here we will state some of the major laws of science. Read it till the end.
Avogadro’s Law
Avogadros’s law states that under the same conditions of temperature and pressure, equal volume of all gases contain equal number of molecules.
Archimedes Principle
Archimedes Principle states that whenever a body is submerged partially or wholly in a fluid (either a liquid or gas), it experiences an upward thrust (buoyant force), whose magnitude is equal to the weight of the fluid displaced by it.
Boyle’s Law
Boyle’s Law states that at a constant temperature, the pressure of a given quantity of gas varies inversely with its volume.
Coulomb’s Law
Coulomb’s Law states that the force of attraction or repulsion between the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Faraday’s Law
Faraday’s laws of electromagnetic induction consists of two laws. They are:
 Whenever the magnetic flux linked with a closed coil changes, an induced e.m.f is produced resulting in a current flow.
 The induced e.m.f is directly proportional to the rate of change of flux.
Gauss’s Law
Gauss’s Law states that the net electric flux associated with any closed surface is always proportional to total electric charge enclosed within it.

Kepler’s laws of Planetary motion is divided into 3 fragments. They are
 All the planets in the universe move in elliptical orbits around the sun which is the focus.
 If we were to draw a line joining the planets , then it would sweep equal areas in equal intervals of time.
 The square of the orbital period of a planet is proportional to the cube of mean distance between the planet and the sun.

Kirchhoff’s Law
 KCL or Kirchhoff’s Current Law states that the current entering the circuit of a node is equal to the current leaving the circuit at the node, provided that it is a closed circuit.
 KVL or Kirchhoff’s Voltage Law states that in a closed circuit, the sum total of voltages at the node is always equal to zero.
Newton’s Law
Isaac Newton proposed three laws of motion, widely known as Newton’s Laws of motion.
 First law of motion states that everybody continues to be in a state of rest or in uniform motion unless acted upon by an external force.
 Second law of motion states that for an object with constant mass, the rate of change of momentum is directly proportional to the amount of force applied.
 Third law of motion states that for every action, there is an equal and opposite reaction.
Ohm’s Law
Ohm’s law states that the current flowing through a conductor(between two points) will always be proportional to the voltage across them.
Snell’s Law
Snell’s law states that the ratio of the sine of the angles of incidence and transmission is equal to the ratio of the refractive indices of the materials at the interface.
Laws of Reflection
According to Euclid’s Laws of Reflection
 The angle of incidence is always equal to the angle of reflection.
 The incident ray, the reflected ray and the normal at the point of incidence all lie in the same plane.

Concluding Note
All of the aforementioned laws play a crucial role in Science as well as our daily life. However, none of these scientific laws were structured or formulated in a day. It took scientists many years of repeated trials, experiments and observations to finally put up a scientific law. These scientific laws help us to determine what will be the result of a certain condition, with the help of proven mathematical equations. Meanwhile, let us not forget that, the scientific laws are not permanent and is subject to change if proven otherwise.
