MADMAN BIOLOGY Energy is a word that means one of these things: Mostly it is used in science to describe how much potential a physical system has to change. In physics, energy is a property of matter. It can be transferred between objects, and converted in form. It cannot be created or destroyed.

energy The capacity or power to do work, such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another.

energy work - (physics) a manifestation of energy; the transfer of energy from one physical system to another expressed as the product of a force and the distance through which it moves a body in the direction of that force; work equals force times distance.nergy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another. It is measured by the amount of work done, usually in joules or watts. See more at law of conservation of energy.

The ability to do work or cause change is called what? Best Answer: That would be the scientific definition of 'energy'. Energy is adherent to the law of conservation of energy, which states that energy is neither created nor destroyed in any action. To illustrate this, just think of a sandwich.

Chemical energy Chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds. The chemical energy in food is converted by the body into mechanical energy and heat. The chemical energy in coal is converted into electrical energy at a power plant. The chemical energy in a battery can also supply electrical power by means of electrolysis.

Energy is the ability to do work, and work's the ability to move an object against a force. So, what is energy? ALL ENERGY is defined quantitatively off being a system's ability to do work stored in a format within the system. It may not really be what you normally consider work, it might be damage instead. Work is a dynamic energy, a transfer of energy from one system to another. Heat is another example of a dynamic energy.

- energy. 1  the capacity for vigorous activity; available power: I eat chocolate to get quick energy. 2  an adequate or abundant amount of such power: I seem to have no energy these days. 3  Often, energies. a feeling of tension caused or seeming to be caused by an excess of such power: to work off one's energies at tennis.

Energy In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.nergy is also transferred from potential energy () to kinetic energy () and then back to potential energy constantly. This is referred to as conservation of energy. In this closed system, energy cannot be created or destroyed; therefore, the initial energy and the final energy will be equal to each other.

Biology book1 By Anne Marie Helmenstine, Ph.D. Energy is defined as the ability to do work. Energy comes in various forms. Here are 5 main types of energy and examples of them. 1  mechanical energy. 2  Mechanical energy is energy that results from movement or the location of an object. 3  Mechanical energy is the sum of kinetic energy and potential energy.

Radiant energy Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to

- From the WebMD Archives. Jan. 2, 2002 -- Toxemia of pregnancy, known medically as preeclampsia, has sometimes been called first pregnancy disease.. Maybe not any more. A new study suggests that later pregnancies get just as risky if a woman waits 10 years between babies. Preeclampsia strikes one in 20 pregnant U.S. women.

Energy: A Scientific Definition Mechanical Energy - Mechanical energy is the sum of the kinetic and potential energy of a body. Light - Photons are a form of energy. Electrical Energy - This is energy from the movement of charged particles, such as protons, electrons, or ions. Magnetic Energy - This form of energy results from a magnetic field.

Energy: A Scientific Definition Energy Definition. Energy is defined as the capacity of a physical system to perform work. However, it's important to keep in mind that just because energy exists, it doesn't means it's necessarily available to do work.

What is energy measured in? In physics, energy is defined as the amount of work that can be performed by force, whereas power is defined as the rate at which work is performed. 1  1 Different Forms of Power and Energy. 2  2 Transformation of Energy. 3  3 Measuring Energy vs. Power.  4 Difference in Units. Energy is usually measured in Joules, the other units include ergs and calories. Power is measured in Watts, which is Joules per second, or ergs per second. Machine are usually described by its power rating, the higher the number the more powerful the machine.

Energy In quantum mechanics, energy is defined in terms of the energy operator as a time derivative of the wave function. The Schrödinger equation equates the energy operator to the full energy of a particle or a system. Its results can be considered as a definition of measurement of energy in quantum mechanics.

- Free Energy refers to a very broad topic of energy. As a part of science we have Thermodynamic Free Energy, which is energy found in a physical system that can be made into work. We have Helmholtz Free Energy, which is energy that can be turned into work at a constant temperature and volume.
