The moment of force, or torque, is a first moment: =, or, more generally, .; Similarly, angular momentum is the 1st moment of momentum: =.Momentum itself is not a moment.; The electric dipole moment is also a 1st moment: = for two opposite point charges or () for a distributed charge with charge density ().
In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. . It is a vector quantity, possessing a magnitude and a directi
The corresponding Latin antonym, ars, is the source of English art, which is not an antonym of inert. Inflammable Flammable Synonym. From Latin flammare meaning "to catch fire". Inflammable is from Latin inflammare meaning "to cause to catch fire". Antonym is nonflammable. [4] Innocent Nocent Rare. Means "harmful". Innocuous Nocuous Uncommon [5 ...
Moment arm diagram. A very useful special case, often given as the definition of torque in fields other than physics, is as follows: = (). The construction of the "moment arm" is shown in the figure to the right, along with the vectors r and F mentioned above. The problem with this definition is that it does not give the direction of the torque ...
Kairos (Ancient Greek: καιρός) is an ancient Greek word meaning 'the right or critical moment'. [1] In modern Greek , kairos also means 'weather' or 'time'. It is one of two words that the ancient Greeks had for ' time '; the other being chronos ( χρόνος ).
Anagnorisis (/ ˌ æ n ə ɡ ˈ n ɒr ɪ s ɪ s /; Ancient Greek: ἀναγνώρισις) is a moment in a play or other work when a character makes a critical discovery.Anagnorisis originally meant recognition in its Greek context, not only of a person but also of what that person stood for.
The action is defined by an integral, and the classical equations of motion of a system can be derived by minimizing the value of that integral. The action principle provides deep insights into physics, and is an important concept in modern theoretical physics. Various action principles and related concepts are summarized below.
Note on second moment of area: The moment of inertia of a body moving in a plane and the second moment of area of a beam's cross-section are often confused. The moment of inertia of a body with the shape of the cross-section is the second moment of this area about the z {\displaystyle z} -axis perpendicular to the cross-section, weighted by its ...
