Introduction The idea of charge represented by Q in an electric field E and an external source of power V is the context set in this tutorial. The effect of the external power on the charge, its relation with electrical field E, and the result of these experiments are worth considering. The charge acquires potential energy as it tries to remain in a position in the electric field. We are interested in the potential energy of the charge in such a field. What Is Potential Energy? The word potential indicates a stored form of something. A compressed spring has ... Read More

Introduction If the position of any object changes relative to the time it is said to be in motion. The motion of any object happens in three ways like one-dimensional motion, two-dimensional motion, and three-dimensional motion. The movement of a train on a straight track, and the circular motion of the top are some examples of motion. This motion of particles is best described by the law of mechanics. Three laws were proposed for the understanding of the movement of an object. When there is a motion then there will be a displacement. What is motion? If the particle moves ... Read More

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. Likewise, the electromagnetic force is the force of attraction or repulsion between charged particles. Magnetic force is part of the electromagnetic force. What are magnets? Magnets are materials that are having a magnetic field around it. Some materials get magnetized by giving magnetic fields. This is known as magnetism. All magnets cannot have the same material. The materials used for magnets are of three types such as diamagnetic materials, ... Read More

Introduction Radiation is a process of transmission of energy from one object to another through the medium or space. It can be ionizing or non-ionizing, which depends upon the energy of the radiation. Ionizing radiation has an energy of more than 10eV and can ionize the particles in their path. X - rays, Gamma rays, alpha emissions, and beta emissions come under ionizing radiation. But non-ionizing radiation has not much energy to ionize the particles in their path. Ultraviolet, infrared, visible, and microwave are some examples of non-ionizing radiation. What is light? Light is electromagnetic radiation and is the ... Read More

Introduction Light is electromagnetic radiation and is the only part of the electromagnetic spectrum that is visible to the human eye. Photon is the basic unit of light. All electromagnetic energy is made up of photons. They are always neutral. That is, they have no electric charge. They do not decay on their own. Within the electromagnetic spectrum, the wavelength range of the light that is visible to the human eye is 400-700nm. What is scattering? When light travels from one medium to another such as air or water, The particles in the medium absorb the light that passes ... Read More

Introduction Poisson's ratio is a very important material property that gives us details about how various materials can deform under fill up. Now let's take an example of the rubber band. If you take a rubber band and stretch it along its length direction, its length increases but you see at the same time in the middle the band will get thinner. So, in this regard Poisson ratio can tell us how much thinner the rubber band is going to end. From the above figure, L is the original length of the band, but after stretch or application of ...

Introduction We know very well that the location of the landmass on earth is changing since it was created. In the beginning, there was a huge single landmass on the earth. But by some natural activities, this huge landmass was split into several parts and also move away from its previous location. At present, there are seven huge land masses known as continents. However, these are also drifting from the location. To define this movement of land masses, scientists proposed a theory known as Plate Tectonics. According to the scientific hypothesis of plate tectonics, the underground activities of the ... Read More

Introduction The neutron was believed to exist before its discovery in 1932 by English physicist Dr James Chadwick. For illustration, it was known that helium had only two protons while having an atomic mass of four. Moreover, after the discovery of neutrons and protons, there was also a new concept that come into play, Isotopes, Isobars and Isotones. The terms are very simple but based on the number of neutrons and protons in the atomic mass unit. What are neutrons? These are the 3 subatomic particles that compose an atom, and the neutron is one among them. It coexists ... Read More

Introduction Neutrons are also known as fundamental building blocks of matter. The rest mass of the neutron is equivalent to 1.67492749×10-27 kg which is just marginally more than that of the proton but about 1839 times more than that of the electron. The neutron seems to have no electric charge. Neutrons are widespread in the universe and account for more than half of all visible matter. Discovery of Neutron The identification of neutrons can be dated to 1930 when German nuclear physicists Herbert Becker and Walther Bothe realized that whenever the alpha particles ejected by polonium were impacted by comparatively ...
