point. Equilibrium Equations The static equilibrium of a particle is an important concept in Statics . A particle is in equilibrium only if the resultant of all forces acting on the particle is equal to zero. In a rectangular coordinate system the equilibrium equations can be represented

Fluid statics print that page


Due to the fundamental nature of fluids, a fluid cannot remain at rest under the presence of a shear stress . However, fluids can exert pressure normal to any contacting surface. If a point in the fluid is thought of as an infinitesimally small cube, then it follows from the principles of

Comparative statics print that page

In economics , comparative statics is the comparison of two different economic outcomes, before and after a change in some underlying exogenous parameter . [ 1 ] As a study of statics it compares two different equilibrium states, after the process of adjustment (if any). It does not

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

History of physics print that page


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

Gottfried Leibniz print that pageTimeline of Gottfried Leibniz


Leibniz occupies a prominent place in the history of mathematics and the history of philosophy . He developed the infinitesimal calculus independently of Isaac Newton , and Leibniz's mathematical notation has been widely used ever since it was published. He became one of the most prolific

Friction print that page

When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat . This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is

History of science print that page


The history of science is the study of the historical development of human understandings of the natural world . Until the late 20th century the history of science, especially of the physical and biological sciences, was seen as a narrative celebrating the triumph of true theories over false
