Doppler Effect

"The Doppler effect is when either the source or observer of a wave in relative motion. The wave is perceived differently by an observer in motion and appears to be squished in front of the path of th ...

Resonance

"Resonance is the forced motion in tune with the nature oscillation frequency of a system, which is called the resonant frequency. Resonance is created when the pushing the system in the right directi ...

Resistors in Series

"Resistors in series are successive resistors in which the same current cannot simply go through one resistor. We can add resistors, but it increases the resistance of the whole network. If one resis ...

Resistors in Parallel

"Resistors in parallel consist of two separate independent circuits so that when the current reaches a resistor, the current can choose which to go through. Most homes are wired in parallel so that u ...

Resistor Circuits

"Resistor circuits are resistor networks which combine resistors in series and resistors in parallel. Removing a resistor in parallel increases the current flow through the other resistor in paral ...

Resistance

"Resistance is the relationship between potential difference and electric current generated. High resistance needs a large potential difference to generate an appreciable current. Electrons will gener ...

Relativity in Motion

"The motion of any object is only meaningful when given relative to something else. Relativity in motion assures us that the laws of Physics don't vary depending on how much inertia an object has. Thi ...

Regelation

"Regelation is the melting and freezing of a substance due to changes in pressure rather than temperature." Fuente: BrightStormRegelation es un contenido didáctico (en inglés) de ©Brightstorm, un espa ...

Displacement

"Displacement is the change in a position vector. It is not the same as distance, which is a scalar measurement. The net vector of multiple displacment vectors if found according to the rules of vecto ...

Diffraction

"Diffraction is the bending of a wave as it changes medium. Waves with small wavelengths, like light, show very little diffraction. Waves with large wavelengths like low pitched sound show major effec ...
