  1. Physical disorder

    Unreferenced date December 2008 A physical disorder as a medical term is often used as a term in contrast to a mental disorder , in an attempt to differentiate medical disorders that have an available objective mechanical test such as chemical tests or brain scans , from those disorders which have no objective laboratory or imaging test, and are diagnosed only by behavioral syndrome such as those in the Diagnostic and Statistical Manual of Mental Disorders DSM . Differentiating physical disorders from mental disorders can be a difficult problem in both medicine and law, most notably because it delves into deep issues, and very old and unresolved arguments in philosophy and religion. Many materialist s believe that all mental disorders are physical disorders of some kind, even if tests for them have not yet been developed and it has been the case that some disorders once widely thought to be purely mental, are known to have physical origins, such as schizophrenia . Some Who date December 2008 psychiatrists take the position that some or all mental disorders may be seen analogously to the information level of programming in a computer. In this case, all such disorders are associated with physical changes in the brain, but the pathology is at the level of brain information and programming software , which is fundamentally separate from the means to store it. Some recognized physical disorders produce significant behavioral changes. For example, fever , head trauma , and hyperthyroidism can produce delirium .

Everything outside the system is known as the environment systems environment , which in analysis is ignored except for its effects on the system. The cut between system and the world is a free choice, generally made to simplify the analysis as much as possible. An isolated system is one which has negligible interaction with its environment. Often a system in this sense is chosen to correspond to the more usual meaning of system , such as a particular machine. But physical systems are often more esoteric an atom, the water in a lake, or indeed the water in the left hand half of a lake can all be considered as physical systems.

  1. Physical change

    Unreferenced date December 2009 Physical change is a concept introduced to contrast with the concept of chemical change . A physical change is any change not involving a change in the substance s chemical identity. Matter undergoes chemical change when the composition of the substances changes one or more substances combine or break up as in a relationship to form new substances. Physical changes occur when objects undergo a change that does not change their chemical nature. A physical change involves a change in physical properties. Physical properties can be observed without changing the composition of matter. Examples of physical properties include texture, shape, size, color, volume, mass, weight, and density. An example of a physical change occurs when making a baseball bat. Wood is carefully crafted into a shape which will allow a batter to best apply force on the ball. Even though the wood has changed shape and therefore physical properties, the chemical nature of the wood has not been altered. The bat and the original piece of wood are still the same chemical substance. Changes are sometimes hard to categorize strictly as physical or as chemical. Dissolving a salt in water involves the breaking of chemical bonds, yet is often described as a physical change. Some teachers hold that a chemical change is a rearrangement of atoms, but many physical changes also involve the rearrangement of atoms. Many chemical changes are irreversible, and many physical changes are reversible, but reversibility is not a certain criterion for classification. Although chemical changes are often recognized by an indication such as odor, color change, production of a precipitate, or production of a gas, every one of these indicators can result from physical change.

  1. Physical strength

    Physical strength is the ability of a person or animal to exert force on physical objects using skeletal muscle muscles . Increasing physical strength is the goal of strength training . Overview An individual s physical strength is determined by two factors the cross sectional area of muscle fibers recruited to generate force and the intensity of the recruitment. Individuals with a high proportion of Muscle fibre Type I type I slow twitch muscle fibers will be relatively weaker than a similar individual with a high proportion of fiber Type II type II fast twitch fibers, but would have a greater inherent capacity for physical endurance. The genetic inheritance of muscle fiber type sets the outermost boundaries of physical strength possible barring the use of enhancing agents such as testosterone , though the unique position within this envelope is determined by training. Individual muscle fiber ratios can be determined through a muscle biopsy. Other considerations are the ability to recruit muscle fibers for a particular activity, joint angles, and the length of each limb. For a given cross section, shorter limbs are able to lift more weight. The ability to gain muscle also varies person to person, based mainly upon genes dictating the amounts of hormones secreted, but also on sex, age, health of the person, and adequate nutrients in the diet. A one rep maximum is the test to determine maximum muscular strength. Strength capability There are various ways to measure physical strength of a person or population. Strength capability analysis is usually done in the field of ergonomics where a particular task e.g. lifting a load, pushing a cart, etc. and or a posture is evaluated and compared to the capabilities of the section of the population that the task is intended towards. The external reactive torque moments and forces on the joints are usually used in such cases.
