Conservation of Energy
The conservation of energy is a fundamental principle in physics, asserting that the total energy within an isolated system remains constant over time, regardless of transformations or exchanges between different forms of energy. This principle, first formulated in the 19th century, underpins numerous scientific theories and practical applications, from understanding the behavior of particles at the quantum level to engineering efficient energy systems. Conservation of energy plays a pivotal role in various fields, including mechanics, thermodynamics, and electromagnetism, guiding research efforts to optimize energy utilization and address environmental concerns surrounding energy production and consumption.
Questions
