In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object. The magnitude of an object's acceleration, as described by Newton's Second Law, is the combined effect of two causes:
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time.
In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If m is an object's mass and v is its velocity, then the object's momentum p is
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.
In physics, the special theory of relativity, or special relativity for short, is a scientific theory regarding the relationship between space and time. In Albert Einstein's original treatment, the theory is based on two postulates:
In mathematics, a tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space. Objects that tensors may map between include vectors and scalars, and even other tensors. There are many types of tensors, including scalars and vectors, dual vectors, multilinear maps between vector spaces, and even some operations such as the dot product. Tensors are defined independent of any basis, although they are often referred to by their components in a basis related to a particular coordinate system.
The Schrödinger equation is a linear partial differential equation that governs the wave function of a quantum-mechanical system. It is a key result in quantum mechanics, and its discovery was a significant landmark in the development of the subject. The equation is named after Erwin Schrödinger, who postulated the equation in 1925, and published it in 1926, forming the basis for the work that resulted in his Nobel Prize in Physics in 1933.
The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations. It was first stated by Benoît Paul Émile Clapeyron in 1834 as a combination of the empirical Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law. The ideal gas law is often written in an empirical form:
In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement. A force is said to do positive work if it has a component in the direction of the displacement of the point of application. A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force.
In biochemistry, Michaelis–Menten kinetics is one of the best-known models of enzyme kinetics. It is named after German biochemist Leonor Michaelis and Canadian physician Maud Menten. The model takes the form of an equation describing the rate of enzymatic reactions, by relating reaction rate to , the concentration of a substrate S. Its formula is given by
In physics and relativity, time dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them or to a difference in gravitational potential between their locations. When unspecified, "time dilation" usually refers to the effect due to velocity.
Gaius Marius "the Younger" was a Roman republican general and politician who became consul in 82 BC with Papirius Carbo. He fought in Sulla's civil war. He committed suicide that same year at Praeneste, after his defeat by Sulla and during the city's capture by Quintus Lucretius Afella.
In linear algebra, an eigenvector or characteristic vector of a linear transformation is a nonzero vector that changes at most by a scalar factor when that linear transformation is applied to it. The corresponding eigenvalue, often denoted by , is the factor by which the eigenvector is scaled.
A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.
Quintus Lucretius Afella was a Roman general who served under the command of Lucius Cornelius Sulla during Sulla's second march on Rome. A loyal legate who expected to be awarded a consulship for his part in Sulla's campaign, he was executed when he tried to defy his master's dictate.
Sulla's civil war was fought between the Roman general Lucius Cornelius Sulla and his opponents, the Cinna-Marius faction, in the years 83–81 BC. The war ended with a decisive battle just outside Rome itself. After the war the victorious Sulla made himself Dictator of the Republic.
The "Béryl incident" was a French nuclear test, conducted on May 1, 1962, during which nine soldiers of the 621st Groupe d'Armes Spéciales unit were heavily contaminated by radioactivity. The test took place at In Eker, Algeria, then a French department, and was designed as an underground shaft test. Due to improper sealing of the shaft, radioactive rock and dust were released into the atmosphere. The soldiers were exposed to as much as 600 mSv. As many as 100 additional personnel were exposed to lower levels of radiation, estimated at about 50 mSv, when the radioactive cloud produced by the blast passed over the command post, due to an unexpected change in wind direction. Among those exposed were several French government officials, including French Defense Minister Pierre Messmer and Gaston Palewski, Minister of Scientific Research.
The Kel Adagh are a Tuareg confederation of clans living in the region of the Adrar des Iforas highlands in Mali. The name comes from Tamasheq "Kel" and "Adagh" ("Mountains"). In the modern era, not all Tuareg in the Adrar des Iforas are Kel Adagh, while some Kel Adagh are spread through northern Niger and southern Algeria, with populations in the Aïr Mountains, Tassili n'Ajjer, and the Hoggar Mountains. Most Kel Adagh derive from Noble and Warrior castes and their tributaries.
Classical mechanics is a physical theory describing the motion of macroscopic objects, from projectiles to parts of machinery, and astronomical objects, such as spacecraft, planets, stars, and galaxies. For objects governed by classical mechanics, if the present state is known, it is possible to predict how it will move in the future (determinism), and how it has moved in the past (reversibility).
Afella Ighir is a small town and rural commune in Tiznit Province of the Souss-Massa-Drâa region of Morocco. At the time of the 2004 census, the commune had a total population of 4205 people living in 1084 households.
