kraft

Also known as mass times acceleration

In physics, a force is an action that can cause an object to change its velocity or its shape, or to resist other forces, or to cause changes of pressure in a fluid. In mechanics, force makes ideas like 'pushing' or 'pulling' mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity (force vector). The SI unit of force is the newton (N), and force is often represented by the symbol .

AI overview

A force is a push or pull that can change how fast or in what direction an object is moving, change its shape, or affect fluids and other forces. Because both how strong a force is and which direction it points matter, scientists use vectors to represent forces mathematically, measuring them in units called newtons.

Kraft är inom fysiken en abstraktion för att förklara och beskriva orsaken till förändringar i ett systems rörelser.I sin nutida mening infördes kraftbegreppet av Isaac Newton. Inom den klassiska fysiken förklarar Newtons tre rörelselagar kroppars rörelse under inverkan av krafter och dessa tre lagar kan sägas definiera krafter som verkar på ett system. De tre lagarna är: * En kropp som inte påverkas av yttre krafter förblir i sitt tillstånd av vila eller likformig, rätlinjig rörelse * Ändringen per tidsenhet av en kropps rörelsemängd är proportionell mot den verkande kraften och ligger i dennas riktning * Mot varje kraft svarar en annan lika stor och motsatt riktad kraft, så att de ömsesidigt mellan två kroppar verkande krafterna alltid är lika stora och motsatt riktade
