Introduction Every matter in the universe is composed of tiny particles called molecules. They attract each other with some attractive force. There exists an intermolecular force of attraction between molecules. Based on the force of attraction between the molecules, matters are classified into five categories. They are solid, liquid, gas, ... Read More

Introduction The movement of the charged particles is responsible for electric energy. Energy obtained from the kinetic energy or potential energy of the charged particles is the electric energy. Charged particles are atoms, molecules, or ions with a charge. The force of attraction or repulsion between the charged particles ends ... Read More

Introduction The electric car is the best achievement by the automobile sector to make the earth pollution-free. Also, it reduces transportation costs due to no fuel charges or lowmaintains costs. If we have a look at the history of the electric car, the first electric car was invented by Gustave ... Read More

Introduction At the molecular level, studying different materials is the job of a material scientist. These scientists study, research, and develop new materials which help shape modern industries. Depending on properties, composition, and other factors, all materials in this world are divided into various types and classes. Polymers are a ... Read More

Introduction The immense importance of Einstein Field Equations ("EFE") warrants a thorough understanding of every single element contained within them. Einstein's equation is another name for the Einstein Field Equation. Ten equations make up this set which is derived from the General Theory of Relativity of Albert Einstein. This tutorial ...

Introduction Every matter in the universe is made up of molecules. So, many atoms contain both positively charged and negatively charged. This force of attraction is known as a chemical bond. This bonding occurs due to electrostatic force between oppositely charged ions or by sharing of electrons. Formerly called ionic ... Read More

Introduction A satellite is an object that revolves around a planet in a curved path. When it comes to satellites, there are two major types of classification. The first is a natural satellite, and the second is an artificial satellite. A natural satellite is one of the celestial bodies that ... Read More

Introduction The classification of science is not limited to the umbrella branches of Physics, Chemistry, and Biology. Instead, even under these branches, we have hundreds of subbranches based on various factors like areas of application, concepts concerned, concepts studied, etc. Classification is important since it makes advanced studies easier. ...

Introduction Initially, electricity and magnetism were treated as separate subjects. In a later period due to the contribution of Oersted, Faraday, Maxwell, etc., it evolved as a unified subject. The current-carrying wire creates a magnetic field around it. Faraday through his experiments showed that current can be produced even if ... Read More

Introduction The particle is considered to be in motion when it changes its position to time. That means the particle is displaced from one position to another. The particle makes linear displacement If it is moving in linear motion. Similarly, the particle makes angular displacement if it is moving in ... Read More
