    Introduction Potential energy is the stored energy of an object based on its position relative to other objects, stresses within itself, its electric charge, or other factors. It is one of the two main forms of energy, the other being kinetic energy. Gravitational Potential Energy Gravitational potential energy is the energy an object possesses due…

    Introduction Lenz’s law is a fundamental principle in electromagnetism, stating that an induced electromotive force (or EMF) always generates a current that opposes the change in original magnetic flux. It is a manifestation of the conservation of energy applied to electromagnetic systems. The Law and Its Interpretation Lenz’s law can be understood in the context…

    Introduction Joule’s Law, named after the English physicist James Prescott Joule, is a fundamental principle in the field of electrical engineering and physics. It describes the relationship between the heat generated and the current flowing through a conductor. Basic Formulation Joule’s Law can be expressed as: where: The heat is measured in joules (J), current…

    Introduction Escape velocity is the minimum speed an object must have in order to escape the gravitational pull of a planet or other body without further propulsion. Essentially, it is the speed needed to break free from the gravitational field of a massive body. Calculation The escape velocity () from the surface of a spherical…

    Introduction Thermodynamics is a branch of physics that studies the relationships between heat, work, temperature, and energy. It describes how energy is transferred and transformed from one form to another, and it is governed by four fundamental laws: the zeroth, first, second, and third laws of thermodynamics. Zeroth Law of Thermodynamics The Zeroth Law of…

    Conservation of energy is the principle which states that the total energy of an isolated system remains constant over time. This principle is based on the idea that energy cannot be created or destroyed, but can only be converted from one form to another. Basic Understanding of Conservation of Energy Energy exists in various forms,…
