Introduction Angular Momentum is a concept of rotational dynamics. We can classify motions of objects in two kinds of motions namely Translational and Rotational motions. In pure translatory motion every point of the body moves in a straight line. Each point covers the same distance in a given time interval. e.g. - A Car moving in a straight line, a man walking on the road etc. Whereas in the pure rotation, the path created by the motion of every point makes a circle whose centre lies on the axis of rotation. E.g. - earth rotating about its axis, spinning top ... Read More

Introduction Radiation is an emission of energy in the form of waves or particles. This includes the emission of Alpha particle, Beta particle, and Gamma particle. Alpha particles are also denoted by Alpha rays or Alpha radiation. It has two protons and two neutrons. What is an Alpha Particle? Alpha particles are formed during α - decay of radioactive elements such as uranium, thorium, radium, and plutonium. Alpha particles are positively charged particles. The alpha particles can be denoted as α or α2+. As alpha particles are similar to helium nuclei they are also denoted as doubly ionized helium ... Read More

Introduction Angle of incidence and its measurement is a key concept of Optics. Light rays when incident on the surface like walls and mirrors, will reflect and get dispersed in the environment. The science of optics studies the traversing of light and its changing characteristics when passing from one medium to another medium. The terms like an incident ray, reflected ray, refracted rays, incident angle refracted angle and reflection, refraction index, and like terms clearly articulate the light characteristics which benefit us in many ways. This article is an attempt to describe the reflection and refraction phenomenon of light and ... Read More

Introduction Density of liquids is different for different types of liquids, which helps to separate them. The density of an item is defined as its mass per unit volume. It is denoted by the character D as well as the symbol ρ, “rho”. The Standard unit of density is kg/m3, which stands for kilogram per cubic metre. Density may be computed using the equation mass divided by volume. A homogeneous substance, such as ice, has identical density throughout because its particles are tightly packed collectively. Density Definition The density of a substance is described as the density of ... Read More

Introduction Density of common substances is an important scientific term with many applications in human life and has a close association with mass. Every matter or the substances that surround us have a mass and that details the quantity or the amount of matter present in that particular substance. Density also has the name specific mass and volumetric mass. Density details the mass and volume of substances taken. The precise measurements of density or the knowledge about density have been very limited during the past centuries. The invention made by Archimedes is responsible for the current facts about density. ... Read More

Introduction Compton shift explains the Compton scattering of electromagnetic radiations. Visible light is electromagnetic radiation and is the only part of the electromagnetic spectrum that can be visible to the human eye. Photon is the basic unit of light. It is a quantum of energy or energy packet in electromagnetic radiation. Albert Einstein explained the fact of discrete energy packets during the transmission of light. And it was first named a photon by Gilbert N. Lewis. They are always in motion and move with the speed of light in a vacuum. All electromagnetic energy is made up of photons. ... Read More

Introduction Conservation of electric charge is one of the basic laws of nature. During the 18th century, one of the physicists named as Benjamin Franklin discovered the electric charge. He started the study of electricity in 1740 itself. For this discovery he went through some experiments and found the existence of the positive charge and negative charge. But this concept came into practice only when the batteries were introduced. Definition of Electric Charge Electric charge is one of the basic physical properties of matter, which is carried out by some elementary particles like electrons, protons, lepton, krypton and meson. ...

Introduction Acceleration is the wrathful of all motion variables as compared to displacement and velocity. You can feel yourself accelerating in scenarios like sitting in a plane during take-off, slamming on the brakes in a car, or speeding around a corner in a go-kart. Any procedure where the velocity varies is referred to as acceleration. There are only two ways to accelerate: changing your speed or changing your direction or changing both. This is because velocity has both a speed and a direction. What is Constant Acceleration? The change in velocity over time is referred to as acceleration. ... Read More

Introduction Conservative forces and non-Conservative forces are the classification in which the forces are divided in Physics. Forces for which the Work done is free of the path through which it is carried are supposed to be Conservative forces. The forces for which the work done is reliant on the path are said to be non-Conservative forces. For Conservative forces, the aggregate sum of mechanical energy always remains constant but for non-Conservative forces, the mechanical energy retained by the body decreases by some amount and is converted to other forms like heat, sound, etc. What is a Conservative Force? ...

Introduction Constant-volume gas thermometer works on the principles of thermodynamics. It us understand this. The best illustration of the zeroth law of thermodynamics is provided by thermometers. Constant-volume gas thermometers are crucial because other thermometers are calibrated using them. A mercury manometer is typically attached to a bulb that is filled with a fixed volume of a diluted gas to create a constant-volume gas thermometer. The manometer is used to gauge pressure variation. According to the Gay-Lussac’s law, an ideal gas's pressure rises in direct proportion to its temperature. Additionally, as temperature drops, so does the pressure similarly drops. ... Read More
