"to the gravitational potential energy, thus The more formal definition is that potential energy is the energy difference between the energy of an object in a given position and its energy at a reference position. Potential energy is closely linked with forces. If the work done by a force on a body that moves from ""A"" to ""B"" does not depend on the path between these points (if the work is done by a conservative force), then the work of this force measured from ""A"" assigns a scalar value to every other point in space and defines a scalar potential"
"an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases"
"space is called proprioception, the perception of body awareness, the ""unconscious"" awareness of where the various regions of the body are located at any one time. Several areas in the brain coordinate movement and position with the feedback information gained from proprioception. The cerebellum and red nucleus in particular continuously sample position against movement and make minor corrections to assure smooth motion. Muscular activity accounts for much of the body's energy consumption. All muscle cells produce adenosine triphosphate (ATP) molecules which are used to power the movement of the myosin heads. Muscles have a short-term store of energy in the"
"term ""potential energy"" was introduced by the 19th-century Scottish engineer and physicist William Rankine, although it has links to Greek philosopher Aristotle's concept of potentiality. Potential energy is associated with forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space. These forces, that are called ""conservative forces"", can be represented at every point in space by vectors expressed as gradients of a certain scalar function called ""potential"". Since the work of potential forces acting on a body"
"to propose that the equivalence of mass and energy is a general principle and a consequence of the symmetries of space and time. A consequence of the mass–energy equivalence is that if a body is stationary, it still has some internal or intrinsic energy, called its rest energy, corresponding to its rest mass. When the body is in motion, its total energy is greater than its rest energy, and equivalently its ""total mass"" (also called relativistic mass in this context) is greater than its rest mass. This rest mass is also called the intrinsic or invariant mass because it remains"
"Energy In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by"
"Power position Power position is a concept from Feng Shui, the ancient Chinese practice of studying one's position within one's surroundings. In Feng Shui, the Power Position or ""Dragon Seat"" is the physical position in the room for a business meeting, which supposedly has the most power. The person in this position can see all entrances to the room, and he or she is seated against a wall or other structure, so that no activity occurs behind the person. This makes this person the focus of attention to everyone else in the room. People who believe this idea believe that"
"Trägheit eines Körpers von seinem Energieinhalt abhängig?"" (""Does the Inertia of a Body Depend Upon Its Energy Content?""), in which Einstein deduced what is arguably the most famous of all equations: . Einstein considered the equivalency equation to be of paramount importance because it showed that a massive particle possesses an energy, the ""rest energy"", distinct from its classical kinetic and potential energies. The paper is based on James Clerk Maxwell's and Heinrich Rudolf Hertz's investigations and, in addition, the axioms of relativity, as Einstein states, The equation sets forth that energy of a body at rest () equals its"
"that moves from a start to an end position is determined only by these two positions, and does not depend on the trajectory of the body, there is a function known as ""potential"" or ""potential energy"" that can be evaluated at the two positions to determine this work. There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong"
"so the reference state can also be expressed in terms of relative positions. Gravitational energy is the potential energy associated with gravitational force, as work is required to elevate objects against Earth's gravity. The potential energy due to elevated positions is called gravitational potential energy, and is evidenced by water in an elevated reservoir or kept behind a dam. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount. Consider a book placed on"

He preferred to refer to it as an ""entelecheia"" or ""living force"" (Latin ""vis viva""), but what he defined is today called ""kinetic energy"", and was seen by Leibniz as a modification of Aristotle's ""energeia"", and his concept of the potential for movement which is in things. Instead of each type of physical thing having its own specific tendency to a way of moving or changing, as in Aristotle, Leibniz said that instead, force, power, or motion itself could be transferred between things of different types, in such a way that there is a general conservation of this energy."
"the intended free energy function is often implicit in manuscripts and presentations. The basic definition of ""energy"" is a measure of a body's (in thermodynamics, the system's) ability to cause change. For example, when a person pushes a heavy box a few meters forward, that person exerts mechanical energy, also known as work, on the box over a distance of a few meters forward. The mathematical definition of this form of energy is the product of the force exerted on the object and the distance by which the box moved (Work=Force x Distance). Because the person changed the stationary position"
"Kinetic energy 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. In classical mechanics, the kinetic energy of a non-rotating object of mass ""m"" traveling at a speed ""v"" is . In"
"Potential energy In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is the joule, which has the symbol J. The"

Since the human body is believed to be imbued with ""qi"" vital energy, the term ""zhengxing"" refers to aligning or harmonizing the flow of vital energy within the physical form (""xing"" 形 literally means ""form; shape""), while ""zhengxin"" refers to aligning the flow of vital energy within the mind (Roth 1991: 612). ""Aligning the body"" and ""aligning the four limbs"" are closely related. The former appears in Verse 11 (above): ""When your body is not aligned [形不正], / The inner power will not"
"body by a supporting surface. A body force is generated by virtue of the position of a body within a force field such as a gravitational, electric, or magnetic field and is independent of contact with any other body. An example of a body force is the weight of a body in the Earth's gravitational field. In addition to the tendency to move a body in the direction of its application, a force can also tend to rotate a body about an axis. The axis may be any line which neither intersects nor is parallel to the line of action"

This tension is a property of the ""pneuma"", and physical bodies are held together by the ""pneuma"" which is in a continual state of motion. The various ""pneuma"" currents combining in this way give objects their stable, physical properties (""hexis""). A thing is no longer, as Plato maintained, hot or hard or bright by partaking in abstract heat or hardness or brightness, but by containing within its own substance the material of these ""pneuma"" currents in various degrees of tension. This can be compared to Aristotle's essential form: in both systems"
"Body capacitance Body capacitance is the physical property of the human body that has it act as a capacitor. Like any other electrically-conductive object, a human body can store electric charge if insulated. The actual amount of capacitance varies with the surroundings; it would be low when standing on top of a pole with nothing nearby, but high when leaning against an insulated, but grounded large metal surface, such as a household refrigerator, or a metal wall in a factory. Synthetic fabrics and friction can charge a human body to about 3 kV. Low potentials may not have any notable"
"Energy homeostasis In biology, energy homeostasis, or the homeostatic control of energy balance, is a biological process that involves the coordinated homeostatic regulation of food intake (energy inflow) and energy expenditure (energy outflow). The human brain, particularly the hypothalamus, plays a central role in regulating energy homeostasis and generating the sense of hunger by integrating a number of biochemical signals that transmit information about energy balance. Fifty percent of the energy from glucose metabolism is immediately converted to heat. Energy homeostasis is an important aspect of bioenergetics. In the US, biological energy is expressed using the energy unit Calorie with"

The amount of energy is directly proportional to the mass of the body: where For example, consider electron–positron annihilation, in which the rest energy of these two individual particles (equivalent to their rest mass) is converted to the radiant energy of the photons produced in the process. In this system the matter and antimatter (electrons and positrons) are destroyed and changed to non-matter (the photons). However, the total mass and total energy do not change during this interaction. The photons each have no rest mass but nonetheless have radiant energy which exhibits the same inertia as did"

"the resulting energy states are related to the frequency by Planck's relation: formula_3 (where formula_4 is Planck's constant and formula_5 the frequency). In the case of an electromagnetic wave these energy states are called quanta of light or photons. When calculating kinetic energy (work to accelerate a massive body from zero speed to some finite speed) relativistically – using Lorentz transformations instead of Newtonian mechanics – Einstein discovered an unexpected by-product of these calculations to be an energy term which does not vanish at zero speed. He called it rest energy: energy which every massive body must possess even when"
"Gravitational energy Gravitational energy is the potential energy a body with mass has in relation to another massive object due to gravity. It is potential energy associated with the gravitational field. Gravitational energy is dependent on the masses of two bodies, their distance apart and the gravitational constant (). In everyday cases only one body is accelerating measurably, and its acceleration is constant (for example, dropping a ball on Earth). For such scenarios the Newtonian formula can – for the potential energy of the accelerating body with respect to the stationary – be reduced to: where formula_2 is the gravitational"
