Physics is a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force.
Physical laws are the conclusions drawn on the basis of long year scientific observations and experiments which are repeated again and again under different conditions to reach the assumptions which can be accepted worldwide. We all know our world works on some principles and these principles are drawn by our scientists in the form of certain physical laws. Important Laws of Physics 1.
Archimedes Principle The principle was discovered in 3rd century B. It states that when a body is partially or totally immersed in a fluid, it experiences an upward thrust equal to the weight of the fluid displaced by it that i. This law states that equal volume of all gases under the same conditions of temperature and pressure contain equal number of molecules.
Ohm's Law It states that the current passing through a conductor between two points is directly proportional to the potential difference across the two points provided the physical state and temperature etc. Do you know why Oil and Water does not mix together? Source: www. Hence, for objects on or near the earth, the mass of the earth is very much greater than the object, and so the gravitational force between them makes objects fall towards the earth. That is why lead and feather fall at the same rate in a vacuum.
It is also called Law of Inertia. This is the principle behind the recoil felt on pulling the trigger of a gun. The SI unit of electric charge, coulomb, is named after Charles Augustin de Coulomb who established the law. Why bursting of Balloon makes sound when pricked with a needle? Hydraulic machines like the hydraulic press work on this principle.
The SI unit of pressure is pascal which is named after Pascal who established this law. Doubling of the tension results in the doubling of the amount of stretch. Bernoulli's Principle It states that as the speed of a moving fluid, liquid or gas, increases, the pressure within the fluid decreases.
The aerodynamic lift on the wing of an aeroplane is also explained in part by this principle. Boyles's Law It states that temperature remaining constant, volume of a given mass of a gas varies inversely with the pressure of the gas.
Kepler's Law Each planet revolves round the Sun in an elliptical orbit with the Sun at one focus. The straight line joining the Sun and the planet sweeps out equal areas in equal intervals.
The squares of the orbital periods of planets are proportional to the cubes of their mean distance from the Sun. Law of conservation of energy It states that energy can neither be created nor destroyed but it can be transformed from one form to another.
Since energy cannot be created or destroyed, the amount of energy present in the universe is always remain constant. Tyndall effect The scattering of light by very small particles suspended in a gas or liquid.

In Chapter 2 we present evidence that scientific research in education accumulates just as it does in the physical, life, and social sciences. Consequently, we believe that such research would be worthwhile to pursue to build further knowledge about education, and about education policy and practice. These are daunting questions that philosophers, historians, and scientists have debated for several centuries see Newton-Smith  for a current assessment.
Although many have taken science classes throughout the course of their studies, people often have incorrect or misleading ideas about some of the most important and basic principles in science. Most students have heard of hypotheses, theories, and laws, but what do these terms really mean? Prior to reading this section, consider what you have learned about these terms before.
Scientists have many tools available to them when attempting to describe how nature and the universe at large work. Often they reach for laws and theories first. What's the difference? A scientific theory often seeks to synthesize a body of evidence or observations of particular phenomena.
What is a scientific theory? How is it different from a law or a principle? And what practical use is it? Science students, especially those new to studying the sciences, ask these questions everyday about these essential parts of a science education. To support these students, the Encyclopedia of Scientific Principles, Laws, and Principles is designed to be an easy-to-understand, accessible, and accurate description of the most famous scientific concepts, principles, laws, and theories that are known in the areas of astronomy, biology, chemistry, geology, mathematics, medicine, meteorology, and physics.

Until the past decade, scientists, research institutions, and government agencies relied solely on a system of self-regulation based on shared ethical principles and generally accepted research practices to ensure integrity in the research process.
