 Conservation Law Enforcement Conservation law enforcement prepares students for a comprehensive understanding of fields related to resource and environmental protection. Building on a broad base of law enforcement knowledge, students learn the importance of integrating science into their theoretical and practical views concerning conservation of our natural resources. Successful students are employable in agencies dedicated to enforcing public and commercial conservation laws at the federal, state and local level. www.unity.edu /ACADEMICS/specificprogram.asp?iden=BS_CON_LAW   (149 words)

 Conservation law - Wikipedia, the free encyclopedia Noether's theorem expresses the equivalence which exists between conservation laws and the invariance of physical laws with respect to certain transformations (typically called "symmetries") for systems which obey the Principle of least action and hence having a Lagrangian and a Hamiltonian (See Classical mechanics, Hamiltonian mechanics for details). For instance, time invariance implies that energy is conserved, translation invariance implies that momentum is conserved, and rotation invariance implies that angular momentum is conserved. 12 is a gentle introduction to symmetry, invariance, and conservation laws. en.wikipedia.org /wiki/Conservation_law   (422 words)

 Conservation of energy - Wikipedia, the free encyclopedia The energy conservation law is possibly the most important, and certainly the most practically useful, of several conservation laws in physics. This is obvious to a modern analysis based on the second law of thermodynamics but in the 18th and 19th centuries, the fate of the lost energy was still unknown. Thus, the rule of conservation of energy was shown to be a special case of a more general rule, alternatively called the conservation of mass and energy, the conservation of mass-energy, the conservation of energy-momentum, the conservation of invariant mass or now usually just referred to as conservation of energy. en.wikipedia.org /wiki/Conservation_of_energy   (1916 words)

 NationMaster - Encyclopedia: Conservation law   (Site not responding. Last check: 2007-10-26) Noether's theorem expresses the fact that any conservation law is equivalent to the invariance of one or more physical laws under certain transformations (typically called "symmetries") for systems which obey the Principle of least action, and hence having a Lagrangian and a Hamiltonian (see Classical mechanics, Hamiltonian mechanics for details). Conservation of energy is possibly the most important, and certainly the most practically useful of several conservation laws in physics. Law of conservation of energy is a mathematical consequence of continuous translational symmetry of time (no moment of time is different from any other). www.nationmaster.com /encyclopedia/Conservation-law   (1273 words)

 Conservation law   (Site not responding. Last check: 2007-10-26) conservation of magnetic flux There are more subtle conservation laws in particle physics like those of spin, baryon number and more recently strangeness. For instance, time-invariance implies that energy is conserved, translation-invariance implies that momentum is conserved, and rotation-invariance implies that angular momentum is conserved. In fact, quantities that are conserved, the invariants, seem to preserve what one would like to call some kind of a 'physical reality' and seem to have a more meaningful existence than many other physical quantities. www.serebella.com /encyclopedia/article-Conservation_law.html   (1784 words)

 conservation law concept from the Astronomy knowledge base conservation of angular momentum (4 facts) - The principle that the angular momentum of a system (the momentum of rotation about a point) remains the same as long as no external torque acts., The total angular momentum of an isolated dynamical system does not change during the course of its evolution. Modern physics has modified the law of conservation of energy, since matter can be created or annihilated; a more general law is the conservation of mass and energy. conservation of mass and energy (3 facts) - Important physical principle and one of the basic laws of physics stating that matter is neither created nor destroyed (although mass may become energy, the energy quantitatively represents the mass). www.site.uottawa.ca:4321 /astronomy/conservationlaw.html   (373 words)

 generic document for building HyperPhysics These quantities are said to be "conserved" and the conservation laws which result can be considered to be the most fundamental principles of mechanics. The conservation of energy principle is one of the foundation principles of all science disciplines. Conservation of Momentum: the mass times the velocity of the center of mass is constant. hyperphysics.phy-astr.gsu.edu /hbase/conser.html   (631 words)

 Momentum Conservation Principle One of the most powerful laws in physics is the law of momentum conservation. For any collision occurring in an isolated system, momentum is conserved - the total amount of momentum of the collection of objects in the system is the same before the collision as after the collision. A vector diagram can be used to represent this principle of momentum conservation; such a diagram uses an arrow to represent the magnitude and direction of the momentum vector for the individual objects before the collision and the combined momentum after the collision. www.glenbrook.k12.il.us /gbssci/phys/Class/momentum/u4l2b.html   (1810 words)

 The laws list: C A law which states that, in a closed system, the total quantity of something will not increase or decrease, but remain exactly the same; that is, its rate of change is zero. There are several other laws that deal with particle physics, such as conservation of baryon number, of strangeness, etc., which are conserved in some fundamental interactions (such as the electromagnetic interaction) but not others (such as the weak interaction). The primary law for electrostatics, analogous to Newton's law of universal gravitation. www.alcyone.com /max/physics/laws/c.html   (1543 words)

 CATHOLIC ENCYCLOPEDIA: The Law of Conservation of Energy Thus stated, the law may be admitted to hold the position of a fundamental axiom in modern physics; the nature of the evidence for it, we shall consider later. His statement of the law was, however, in advance of the existing experimental evidence, and he was led to it partly by philosophical reasoning, partly by consideration of physiological questions. A law of nature must be founded on experiment and observation, and the general agreeement of the law with facts leads to a general belief in its probable truth. www.newadvent.org /cathen/05422a.htm   (6294 words)

 The Law of Action-Reaction (Revisited) In the second unit of The Physics Classroom, Newton's third law of motion was introduced and discussed. In accord with Newton's second law of motion, the acceleration of an object is dependent upon both force and mass. According to the law, the force exerted by object 1 upon object 2 is equal in magnitude and opposite in direction to the force exerted by object 2 upon object 1. www.glenbrook.k12.il.us /gbssci/phys/Class/momentum/u4l2a.html   (1066 words)

 Limitation of the Law of Energy Conservation The law of conservation of energy is today an accepted doctrine that governs all energy-exchange phenomena of nature. At that stage (1931) when the law of conservation of energy was threatened, the existence of a new particle (neutrino), till then unknown, was postulated to save the law. However, when the spatial reality of fields and absence of energy at electron's centre are recognized, the law of conservation of energy becomes applicable only to the universe as a whole, though for the phenomena involving material interactions due to conservation of momentum, the energy conservation law will be valid also in isolated systems. depalma.pair.com /Tewari/Chap8.html   (3478 words)

 Conservation law   (Site not responding. Last check: 2007-10-26) The following list is partial listing of conservation laws that have been shown to be inexact (actually though General relativity energy momentum and angular momentum are conserved in general because a general curved manifold would not possess Killing symmetries for or rotations): Noether's theorem expresses the equivalence which exists between laws and the invariance of physical laws with respect to transformations (typically called " symmetries ") (This only applies to systems describable a Lagrangian). In fact quantities that are conserved the invariants seem to preserve what one would to call some kind of a 'physical and seem to have a more meaningful than many other physical quantities. www.freeglossary.com /Conservation_laws   (515 words)

 delawareonline ¦ The News Journal ¦ Conservation law gets second wind Although the law calls for updates every five years, the version now before the council would be the first change in the map. A 15-year-old state conservation law that went mostly unenforced as sprawl chewed up Delaware's farms and woodlands has re-emerged as the centerpiece of a new attempt to rein in development. While state law requires counties to take state resource areas into account as part of their comprehensive plans and development reviews, none of the counties is in compliance, the 1999 report pointed out. www.delawareonline.com /apps/pbcs.dll/article?AID=/20060122/NEWS/601220340/1006/RSS   (1499 words)

 Conservation of Energy The conservation of energy is a fundamental concept of physics along with the conservation of mass and the conservation of momentum. On some separate slides, we have discussed the state of a static gas, the properties which define the state, and the first law of thermodynamics as applied to any system, in general. On this slide we derive a useful form of the energy conservation equation for a gas beginning with the first law of thermodynamics. www.grc.nasa.gov /WWW/K-12/airplane/thermo1f.html   (672 words)

 Review: Conservation and the Law: A Dictionary   (Site not responding. Last check: 2007-10-26) More than a list of relevant laws, this introduction offers an examination of the players involved, the philosophical basis for their actions, dominant themes, and the varied nature of the law itself that forms the backbone of the conservation movement here. The reader is referred to Environment and the Law: A Dictionary (1995), which is a companion text in the series "Contemporary World Issues." Entries include specific laws, conservation organizations, political figures, government agencies, legal doctrine, resource management techniques, and fields of applied science. Donahue’s background as associate professor of law at the University of Wyoming plus her experience in private practice and as staff counsel for the National Wildlife Federation qualify her to write this helpful reference work. egj.lib.uidaho.edu /egj11/johnson2.html   (425 words)
