Brownian Motion

Brownian motion is the random and irregular motion of gas and liquid molecules. Brownian motion provides clear evidence for the kinetic molecular model of matter in that matter is comprised of tiny particles that are in continuous random motion, with a range of speeds n all directions and kinetic energies. In the simulation above, it is seen that the particles …

Three States Of Matter

The three states of matter are solid, liquid and gas. Solid Solids have strong atomic bonding and high viscosity, resulting in high density, highly incompressible and hence, an inflexible shape. The atoms/molecules in a solid are closely packed together and occupy minimum space, usually in a regular pattern. Due to strong intermolecular attractive and repulsive forces, motion is limited to …

The Physics of Airplane Flight

The following article is about the physics behind the flight of airplanes. There are no equations in this articles. (great!) Source: Yahoo Associated Content Did you know Boeing wasn’t one hundred percent sure the 747 could fly until it actually did? It was faith in physics that reassured the engineers (and bankers) that such a massive undertaking was worth the …

Properties Of Waves

Amplitude Amplitude is the maximum displacement from the rest or central position, in either directions. SI unit is metre Scalar quantity   Frequency Frequency (f) is defined as the number of complete waves produced per unit time. SI unit is hertz (Hz) – 1 Hz = 1 complete cycle per second Scalar quantity Determined by the source (for water waves) …

What Is A Wave?

Wave is defined as the propagation of periodic disturbances from one region to another, without the transfer of any material medium. Source of a wave: vibration or oscillation There is a transfer of energy from one point to another without the transfer of any material between the two points. Can be classified into two types: transverse waves and longitudinal waves …

Quantum Physics and Its Tie to Metaphysical Possibilities

I stumbled across this article while browsing the web and i thought it would be a good addition to this blog. Note: This is metaphysics. If you are studying for ‘A’ level, do not read this. (you may be confused) Source: Yahoo Associated Content Do you remember a time in your life when things fascinated you? Do you recall being …
