"Convection is the movement of warm particles within fluids. Convection is often found in the air as heated air rises and cool air falls. This is because hot molecules spread apart, making them less d ...

"The continuity equation deals with changes in the area of cross-sections of passages which fluids flow through. Laminar flow is flow of fluids that doesn't depend on time, ideal fluid flow. The formu ...
"Power is the rate at which work is done. It is related to energy, which is the quantity used to measure work. Power can be calculated by the ratio power = work / time and is usually measured in Watts ...
Video Física
"Objects store energy in the form of potential energy. Chemical potential energy is an object's potential to undergo an exothermic reaction; spring potential energy is a compressed spring's potential ...

"Potential difference is what we use to generate current and to make it do what we want it to. Batteries serve as a constant source of potential difference in order to force the current to flow. " ...
"The law of conservation of momentum says that if two objects collide, the force lost by one object is equal to the force gained by the other object. The total momentum of the system is the same after ...

"The law of conservation of mass states that mass is neither created nor destroyed. In a closed system, mass of reactants is equal to mass of products. The law of conservation of mass is related to th ...

"Conductors have a flow of charge through the conduction band. Metals are extremely good conductors. In general, charge congregates at sharp points. Conductivity is related to electric fields by th ...

"Conduction is a type of thermal energy transfer involving direct contact. The more tightly packed the molecules within a substance are, the more conductive the substance is." Fuente: BrightStormCondu ...

"Condensation is the change in phase of a gas upon the surface of a solid due to its loss of energy to that solid. Water droplets often form on the surface of cool substances because the water vapor i ...
