Work, Energy, and Power

Introduction Energy is a property of physics that must be transferred to a physical system or a body to work on and/or heat it. Movement is simply the result of energy. Energy is a conserved quantity. The law of conservation of energy states that energy cannot be created or destroyed. Energy can be transformed into […]

The energy within a system is not maintained by a nonconservative force, but is instead released out of the system. As a result, these forces are often referred to as dissipative forces.When the path is a closed loop, the total work done by a conservative force is independent of the path that results in a

Conservative force is the force applied to move a particle from one point to another. It is not dependent on the path taken by the particle. It only depends on two factors: the initial and final positions of the particle. The conservative force is responsible for the orderly motion of particles and atoms in a

Work done by a conservative force is defined as the work done by a body when it is in equilibrium with a conservative force acting upon it. In contrast to work done by a body when it is in equilibrium with a non-conservative force, work done by a conservative force is known as static work.

Power The rate at which energy is transported or converted, or the rate at which labour is performed, is referred to as power. It is the quantity of work completed per unit of time in technical terms. Watt (W), or joules per second (J/s), is the SI unit of power. Horsepower (Hp), which is roughly

In physics, we come across a variety of quantities with different properties, and characterising them gets problematic when we talk about terms like energy, time, work, or any other physical quantity that requires a standard measure to identify. The units establish the standard measure of certain quantities in physics. For example, let’s imagine a person

Energy surrounds the activities and the work that we do. The steps you take to school or the plant that you grow, every activity involves energy. In the simplest sense, energy refers to the ability to do work. Energy in physics can be of various kinds. There is kinetic energy, potential energy, mechanical energy and

You must have wondered at least once how spring can regain its normal shape even though you put huge force while stretching and compressing it. Why does one need to put additional stress to modify the position of the spring? This is the spring’s potential energy; its formula is illustrated as PE = force x

Generators are devices that can be used as alternative to the current supply. They’re also used in industries including road construction, mining, offshore drilling, outdoor shooting, and event management to meet power demands.  Generators use the principle of electromagnetic induction to generate electric energy in the form of current and voltage. We will learn about the

Electric power is an essential element of our daily life. Without electric power, humans would not have had the chance to invent and develop the technology that we have today. Electric power is used in various sectors, including industry, household, entertainment, and work. It is safe to say, without electrical energy, our life would be
