One thing that uses magnetic fields is the electric motor‚ which is used in many household appliances‚ such as electric fans‚ microwave ovens‚ and other small appliances. In this instance the electric motor has an electric current‚ giving it also this magnetic field. An electric motor converts electricity into mechanical motion. Most electric motors work by electromagnetism‚ but motors based on electrostatic forces also exist. The overarching concept is that a force is generated when a current-carrying

Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) “knowledge of nature”‚ from φύσις phúsis "nature"[1][2][3]) is the natural science that involves the study of matter[4] and its motion through space and time‚ along with related concepts such as energy and force.[5] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[a][6][7] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy

that into a systematic method for finding sides and angles of triangles. The ancient Nubians used a similar methodology.[5] The ancient Greeks transformed trigonometry into an ordered science.[6] Classical Greek mathematicians (such as Euclid and Archimedes) studied the properties of chordsand inscribed angles in circles‚ and proved theorems that are equivalent to modern trigonometric formulae‚ although they presented them geometrically rather than algebraically. Claudius Ptolemyexpanded upon Hipparchus’

Simple Machine Joemarie A. Martinez 1-D CE Simple machine Simple machines make work easier by multiplying‚ reducing‚ or changing the direction of a force. The scientific formula for work is w = f x d‚ or‚ work is equal to force multiplied by distance. Simple machines cannot change the amount of work done‚ but they can reduce the effort force that is required to do the work! As you can see by this formula‚ if the effort force is reduced‚ distance is increased. These simple machines

Names for the war Further information: Terminology of the Vietnam War Various names have been applied to the conflict. Vietnam War is the most commonly used name in English. It has also been called the Second Indochina War and the Vietnam Conflict. As there have been several conflicts in Indochina‚ this particular conflict is known by the names of its primary protagonists to distinguish it from others.[56] In Vietnamese‚ the war is generally known as Kháng chiến chống Mỹ (Resistance War Against America)

History of Robotics: Timeline This history of robotics is intertwined with the histories of technology‚ science and the basic principle of progress. Technology used in computing‚ electricity‚ even pneumatics and hydraulics can all be considered a part of the history of robotics. The timeline presented is therefore far from complete. Robotics currently represents one of mankind’s greatest accomplishments and is the single greatest attempt of mankind to produce an artificial‚ sentient being. It is

Science is a body of empirical‚ theoretical‚ and practical knowledge about the natural world‚ produced by researchers making use of scientific methods‚ which emphasize the observation‚ explanation‚ and prediction of real world phenomena by experiment. Given the dual status of science as objective knowledge and as a human construct‚ good historiography of science draws on the historical methods of both intellectual history and social history. Tracing the exact origins of modern science is possible
