Physics print that page

CollageFisica

Physics is one of the oldest academic disciplines , perhaps the oldest through its inclusion of astronomy . [ 6 ] Over the last two millennia, physics was a part of natural philosophy along with chemistry , certain branches of mathematics , and biology , but during the Scientific Revolution

Spin (physics) print that page

In quantum mechanics and particle physics , spin is a fundamental characteristic property of elementary particles , composite particles ( hadrons ), and atomic nuclei . [ note 1 ] All elementary particles of a given kind have the same spin quantum number , an important part of a particle

Drag (physics) print that page

Drag_Curve_2

In fluid dynamics , drag (sometimes called air resistance or fluid resistance ) refers to forces that oppose the relative motion of an object through a fluid (a liquid or gas ). Drag forces act in a direction opposite to the oncoming flow velocity . [ 1 ] Unlike other resistive forces

History of physics print that page

Libr0310

As forms of science historically developed out of philosophy , physics (from Greek : φύσις physis " nature ") was originally referred to as natural philosophy , a term describing a field of study concerned with "the workings of nature". Contents 1 Early history 2 Galileo

Rayleigh-Taylor_instability

Computation now represents an essential component of modern research in accelerator physics , astrophysics , fluid mechanics , lattice field theory / lattice gauge theory (especially lattice quantum chromodynamics ), plasma physics (see plasma modeling ), solid state physics and soft

Causality (physics) print that page

equal probability of stopping at each position. [ edit ] Various concepts of cause and effect in physics In physics it is useful to interpret certain terms of a physical theory as causes and other terms as effects. Thus, in classical (Newtonian) mechanics a cause may be represented by

Digital physics print that page

In physics and cosmology , digital physics is a collection of theoretical perspectives based on the premise that the universe is, at heart, describable by information , and is therefore computable . Therefore, the universe can be conceived as either the output of a computer program or

Plasma (physics) print that page

Plasma-lamp_2

In physics and chemistry , plasma is a state of matter similar to gas in which a certain portion of the particles are ionized . Heating a gas may ionize (reduce the number of electrons in) its molecules or atoms, thus turning it into a plasma, which contains charged particles: positive

Motion (physics) print that page

Leaving_Yongsan_Station

In physics , motion is a change in position of an object with respect to time. Change in action is the result of an unbalanced force . Motion is typically described in terms of velocity , acceleration , displacement and time . [ 1 ] An object's velocity cannot change unless it is acted
