energiá
Energiá is a fundamental concept in physics and daily life, defined as the capacity to perform work or cause change in a system. It takes many forms and can be transferred or transformed between objects and processes. In physics, energiá is a property that changes with the system’s state.
The standard unit of energy in the International System is the joule (J). Larger quantities are commonly
Key forms of energiá include kinetic (motion), potential (position), thermal (temperature-related), chemical (bonds), electrical, radiant (light),
Energy is conserved in isolated systems; the first law of thermodynamics states that energy cannot be created
Sources of primary energiá include fossil fuels, solar, wind, hydro, geothermal, biomass, and nuclear energy. These
Understanding energiá, efficiency, and supply security is essential for technology, industry, and climate policy. Global trends
