Electric Current
Electric current is the flow of electric charge, typically carried by charged particles such as electrons or ions, through a conductor or in a circuit. It is a fundamental concept in the study of electricity and is at the heart of countless devices and technologies, from power generation and distribution to electronics and telecommunications. Basic…

Electric Charge
Electric charge is a property of matter that gives rise to the electromagnetic force, one of the four fundamental forces in nature. It is responsible for the interactions between charged particles, such as electrons and protons, and is the basis for a wide range of phenomena, from static electricity to the flow of electric current…

De Broglie Wavelength
The de Broglie wavelength is an important concept in the field of quantum mechanics as it relates the wavelength of a particle to its momentum. It demonstrates the wave-particle duality of matter, which is the idea that particles at the quantum level exhibit both wave-like and particle-like behavior. Basic Understanding of De Broglie Wavelength In…

Dark Matter
Dark matter is a hypothetical form of matter that is thought to account for a significant portion of the total mass in the universe. Although it has not been directly observed, dark matter is inferred to exist due to its gravitational effects on visible matter, such as stars and galaxies, as well as its influence…

Dark Energy
Dark energy is a theoretical form of energy that is thought to be responsible for the observed accelerated expansion of the universe. This mysterious and still poorly understood form of energy was first proposed in the late 20th century to explain the unexpected findings from observations of distant supernovae. Basic Understanding of Dark Energy In…

Coulomb’s Law
Coulomb’s Law is vitally important in the field of electrostatics as it describes the force between two charged particles. This principle is named after the French physicist Charles-Augustin de Coulomb, who formulated the law in the late 18th century. Basic Understanding of Coulomb’s Law Coulomb’s Law states that the electrostatic force between two charged particles…

Conservation of Momentum
Conservation of momentum is the principle which states that the total momentum of an isolated system remains constant over time, provided no external forces act on the system. This principle is based on the idea that momentum, like energy, cannot be created or destroyed, but can only be transferred between objects. Basic Understanding of Conservation…

Conservation of Energy
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,…

Velocity
Velocity is a vector quantity that describes the rate at which an object changes its position. It is defined as the displacement of an object per unit of time and has both magnitude and direction. Velocity is often measured in meters per second (m/s), but other units such as feet per second (ft/s) or miles…

Centripetal Force
Centripetal force is the force that is necessary to keep an object moving in a circular path. When an object is moving in a circle, it is constantly changing direction, which means it is also constantly accelerating. Centripetal force is the force that causes this acceleration. This is required by Newton’s Second Law: or, in…
