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. All matters in the universe are considered as a physical system. These are analyzed by the laws of physics. Every object in the universe cannot move without external force. If force is applied to the object. It will be stored inside and then released in the form of work. What is Energy? The capacity of the physical system that needs to do work is called the energy of the ... Read More

There exists an intermolecular force of attraction between molecules. Every object in the universe cannot move without external force. If force is applied to the object. It will be stored inside and then released in the form of work. What do you mean by Energy Consideration? Energy consideration gives the relation between the force applied and the energy needed for applying the force. Lenz’s law is stable with the law of conservation of momentum. While discussing the energy ... Read More

Introduction Kinetic energy is the energy related to motion. For an object which is stationary, there is no kinetic energy. In this article, we are not talking about any energy change. For example, water is converted to heat energy and thus steam when heated. We can find many such energy changes in the environment and day-to-day life, but they are out of scope in this article. Here we discuss the kinetic energy which is associated with objects in motion. A moving object acquires kinetic energy due to the force applied to it, which can be expressed by an equation $\mathrm{KE=\frac{1}{2}mv^2}$ ... Read More

Introduction With rapid development and modernization, the need for abundant low-cost energy is growing tremendously. To fulfil these energy requirements, humans exploit energy resources in various ways. Although the various techniques and procedures followed in this process impact the environment positively, the negative impacts are much more harmful and of major concern to the sustainable development of society. What is an Energy Resource? Energy resource, as the name suggests, can be defined as a natural resource that can either acts as a source or can be converted into other forms of energy via human intervention to fulfill the energy needs. ...

Introduction Both the aspects of the momentum and kinetic energy are crucial in the field of physics, as momentum is said to describe the relationship with certain specified aspects. These aspects are speed, mass and direction for a concerned object having considerable mass. On the other hand, kinetic energy is the energy within a mass associated with motion. The energy within the body is inherited due to the motion exerted on a body. Kinetic energy is stated as the potentiality to conduct work. Definition of Kinetic energy In the subject of physics, several types of energies are noticed that are ... Read More

Introduction Energy is abundant in nature and it exists in multitudes of forms that can transform from one form of energy into another. These energies are mainly classified into potential and kinetic energy these energies can however be sub-divided into various other categories that have their own set of distinct functionalities and principles. These energies however can be subdivided into various other forms like gravitational energy, atomic energy and many more. The kinetic energy is the kind of energy that is mostly available in the moving objects. The potential energy is classified into the form of ... Read More

Introduction Solar energy has been utilised for more than 2700 years for cooking, heating and other important applications that create a life more effectively. The Sun is powerful and has always been a crucial resource for humanity where the energy of the sun is considered to be inexhaustible. Solar energy possesses a positive impact on the environment and replenishes environmental factors. Recently, the norms of solar energy projects have been popular due to the excessive usage of fossil fuels on the environment. The project of solar energy has been gradually developing with the use of innovative technology. The renewable ... Read More

Introduction Solar cars used solar energy and it has different benefits. Solar cars use the energy of the sun and make a charge through the energy. It is created through the energy of the sun and great developed technology is needed for this. It is a pollution-free concept and makes less noise than traditional cars. What is Solar Car? Solar power car used the power of solar or the sun and it does not run through fossil fuels. It is seen that the sun is the main source of a charge for this car and it gives an electric ...

Introduction From ancient times, sunlight was used as a source of energy. It is believed that the knowledge of solar energy existed in some of the oldest civilizations like the Greeks, and Romans, though they have not used it for cooking. Food can be made by using the sunlight this principle comes much later and was developed approximately in the 1870s. The solar cooker is a low-tech device and can be made at a very less cost, however, it has its advantages and disadvantages. What is a solar cooker A solar cooker can be defined as a device ...

Introduction A photovoltaic cell is also known as a PV cell, an electrical device that is used for converting solar energy into electric energy, and that is how the cell and the solar energy are connected. To use solar energy, PV cells are most needed. Solar energy is radiation that directly comes from the sun and is capable of through some chemical reaction it is capable of producing heat and can generate electricity. What is Solar Energy Solar energy can be defined as the light and heat that comes from the sun and is radiated and harnessed through ... Read More
