Conservation of energy

Mass-energy relation expresses that each article has specific energy even in a fixed position. A fixed body doesn’t have active energy. It just has expected energy and likely compound and nuclear power. As indicated by the field of applied mechanics, the amount of this multitude of points is more modest than the result of the particle’s […]

In physics, power is an important quantity that relates to Work and Energy. Physics defines work done as the product of an object’s displacement and external force applied. The capacity to get the work done is called energy. However, we need work done and time as the driving units to define power. There are many

Every object around us possesses mechanical energy. Whether it is a hand that swings the tennis racket or a rotating fan in our living room, they all move due to mechanical energy. All the simple and complex systems that exert force – use mechanical energy to get the work done. An aeroplane takes off by

Machines that are used to do useful work by converting heat into mechanical energy are known as Heat engines. These heat engines receive heat from the ignition of fuel, coal, petrol, or other energy sources. There are three parts of heat engines – source, or hot reservoir, the working body, and cooler or sink or

Power is defined as the amount of work done per unit of time. In an alternating current circuit, power is given by the product of voltage and current. However, values of voltage and current change every instant in an AC circuit. Therefore, the power in an AC circuit at any instant of time is calculated

The physical world can be broken down into interactions between different types of forces, and it is these interactions that give meaning to all the phenomena we witness. In our daily lives, too, all our activities involve the application of force in some form or other. But, all activities ranging from the movement of particles

Converting electron volts to joules is also useful for solving a variety of scientific difficulties. The values in the table are quite valuable for making calculations easier. For better outcomes, you must grasp the concept and memorise the conversion values. Both are widely used as energy units. When an electron is pushed across a potential

Introduction In many circumstances, it is required to assess the energy consumption of any electric equipment, such as the TV, refrigerator, oven, and washing machine in a home. And we pay the electric bill on a regular basis, and we can compute the amount of money payable for electricity consumption if we know how much

Conventional sources of energy Natural energy supplies that are restricted in quantity and have been used for a long time are known as conventional sources of energy. They’re considered non-renewable sources because once they’re depleted, they can’t be produced at a rate that can keep up with the rate of use. They are made up

Introduction So, in our surroundings, there are various types of force acting. In physics, force plays a very important role. Any interaction will change the motion of an object when unopposed is understood as force. Forces can be classified into two types of forces, Conservative forces and Non-conservative forces. Most crucial aspect of physics is
