Introduction Johannes Rydberg, a Swedish physicist introduces the Rydberg formula which represents the fundamental constant of the atomic physic. It describes the frequencies or wavelengths of light in different series which is related to the spectral line. Especially it emphasizes those which are emitted by hydrogen atoms from the Balmer series. The standard of this constant is generally founded on a premise. A nucleus of an atom generally emits light which is extremely massive in comparison to the electron which is single orbiting. The certain value of Rydberg constant is 10, 973, 731.56816 per meter. Rydberg Constant and its explanation ... Read More

Introduction The kinetic energy value of a centre of mass and of an extended object can be expressed with rotational kinetic energy. Both the linear and the rotational kinetic energy is developed based on the work-energy principle in a parallel manner. The representation of the rotational kinetic energy is done based on the particular axis of the object’s rotation. Rotational Kinetic energy: Analysis During the time of an object’s rotation, rotational energy occurs. A significant part of total kinetic energy is named rotational energy. The moment of inertia occurs at the time when the rotational energy occurs separately based on ... Read More

Introduction The spinning motion of an object, around its own axis is referred to as rotation. An object's orbital motion that is cantered on any other object is known as the revolution. The earth rotates around itself and produces day and night. This is an example of rotation and when it moves around the Sun in a particular path this is regarded as a revolutionary process. Description of Rotation Based on a centre of a particular object, the rotation is a significant and circular movement. The two most important elements of a rotation are the centre of the whole rotation ... Read More

Introduction The rolling motion refers to the combination of a type of translation motion as well as a rotational motion of an object. For example, in a machinery body, the rolling motion differs from the mass centre motion, which also signifies a type of translation motion of that particular body. During the time of the rolling motion of a machinery particle, the surface gets in close contact for a temporary period. During the rolling motion of a rigid body without slipping the particular object comprises the translational force, as well as rational motions during the surface contact, is ... Read More

Rolling Friction and Rolling Resistance

Introduction Rolling friction and rolling resistance refer to the force that helps to resist the rolling motion of the machinery body of the surface. For example, it is commonly seen that pulling a heavy almirah on a rough surface is so tough but if an iron wheel is used then the pulling, the process becomes easier. It has happened just because iron wheels do not slide on the floor but roll on the floor. The velocity of the point of the wheel with the floor remains zero and that is why the iron wheel proceeds smoothly on the floor. ... Read More

Introduction Rolling friction is the type of friction in which the force resists the rolling object's motion on the surface. Rolling friction assists in minimising the friction between the surface and an object which is relatively lower as compared to sliding friction. Rolling friction permits the object to go smoothly over the surface and roll up the hill. The wheels fitted on the luggage work on the concept of rolling friction as it is rolled and moved easily with the wheel. At a certain point, the surface and object deform in rolling friction due to certain factors such as roughness, ... Read More

Introduction The idea of Rocket science was developed by Konstantin Tsiolkovsky, a Russian school teacher in 1898. In 1898, the schoolteacher proposed the idea of exploring the full space area by rocket. Robert Hutchings Goddard, a physicist, professor and engineer built the first liquid-fuelled rocket and launched it in the year 1926 in the era of innovation and space light. Rocket science is based on the principle and works on the concepts of physics and works in both small paper ones and Nasa rockets. Calling from different places, watching television and many more have become possible with the emergence of ... Read More

Introduction Rocks that are available in nature are subjected to changes in shape and size. The process of the rock cycle is a standard concept in the study of geology that governs the aspect of the transition in the states of rock. The rocks found in nature are constantly being recycled over a certain period. These rocks undergo various stages of chemical and physical changes that alter their structure. The three key forms of rocks that are found in nature are sedimentary, metamorphic and igneous rocks. Rock cycle The rock cycle is the process that defines the transition of the ... Read More

Introduction The root mean square of the current value is instantaneous. This value of the alternating current is denoted as a value of a stable current. this steady current helps in the generation of an equal amount of heat in a particular resistance within a given period as it is done by a.c current. This happens in the same manner when the ac is regulated across a similar resistance for the same period. What Is Alternating Current? The value of an alternating current can be illustrated as a current flow that alters its magnitude and value of polarity at the ... Read More

Introduction The Rigid body can also be described as particles collection with the property where the distance between particles is unchanged at the time of course of motions of the body. The axis around which the body keeps rotating either in a circular path is called the axis of rotation. The dynamics and kinematics of rotation of a rigid body mainly take place around an axis. Here the axis that is fixed is determined to be fully analogous to those of linear motion along one fixed direction and is considered to be in the rotational motion. What is motion? ... Read More
