In our everyday, experience, besides gravitational force, we encounter several kinds of forces like frictional force, the force of buoyancy and viscous force, contact force between the bodies, the force due to surface tension of a liquid and so on. In later 20th century, we come to know that these different forces occurring in different … Read more
Introduction:- The atomic theory of matter was first proposed by john Dalton, in 1808. His theory, called Dalton’s Atomic Theory, regarded as the ultimate particle of matter. This theory was able to explain the law of conservation of mass, law of constant composition and law of multiple proportion. However, it failed to explain the results … Read more
In earlier time scientist of different countries were using different systems of units for measurement. Some of these systems are:- CGS System :- In this system centimeter, gram and second are the fundamental units of length, mass and time respectively. It is a metric system of units. It is also known as Gaussian system of … Read more
Chromatography is a modern and sensitive techniques used for rapid and efficient separation or analysis of components of a mixture and purification of the compounds. The name chromatography is based on the greek word Chroma meaning colour and graphy for writing because the method was 1st used for the separation of coloured substances found in … Read more
Physics and technology have a deep impact on society, enabling advancements in various fields such as communication, medicine, transportation, energy, and even entertainment. The interaction between these three physics, technology, and society forms a continuous cycle of innovation and growth, transforming human existence in countless ways. The Role of Physics in Technology The principles of … Read more
Matter is thing that occupies space and has mass. Matter exists in three physical states: Solid, liquid and gas. In this note we will focus on understanding the physical properties of matter and how they can be measured. Properties of Matter Physical Properties are associated with physical existence of matter. These are inbuilt characteristics of … Read more
The organic compounds whether isolated from a natural source or prepared in the laboratory are mostly impure. These are generally contaminated with some other substances. A number of methods are available for the purification. The choice of a particular technique or method depends upon the nature of the compound whether solid or liquid and also … Read more
Introduction Moment of inertia functions in a manner similar to mass in linear motion but with rotating motion. Measurement of an object’s resistance to variations in its rotational motion along an axis is known as its moment of inertia. It is more difficult to accelerate or deaccelerate an object’s rotation the greater its moment of … Read more
It serves as the foundation for more complex topics in rotational dynamics and mechanics. Center of mass is the precise location within a body or system of particles where all of the system’s mass is thought to be concentrated. Since this point acts as though all external forces are acting directly on it, knowing where … Read more
Periodic table‘s first element, beryllium (Be), belongs to Group 2 (alkaline earth metals), and it differs greatly from the other elements in its group in a few key ways. We call this phenomena the “anomalous behavior of beryllium.” Beryllium is unique among alkaline earth metals despite their overall similarities. Its small atomic and ionic size, … Read more
