Brownian Motion is the phenomenon whereby particles suspended in a fluid move in stochastic (i.e., pseudo-random) paths resulting from their bombardment by the fast moving atoms or molecules in the fluid, even if it is calm. In order for these kinetic impacts to take...
In physics, what is the difference between a mixture and a compound?
By: Francis Harris
Compounds and mixtures are easy concepts to understand. Chemically the difference between them lies in their atoms and whether the atoms of different elements are chemically joined (compound) or just mingled (mixture) together. This chemical difference affects how compounds and mixtures may be separated back...
In physics, what is the principle of moments?
By: Francis Harris
In physics the concept of moments has nothing to do with time but is rather a measure of the energy in a system. Moments, or the torque of a force, about a turning point are measured in Newton meters (Nm). Moments capture the turning effect...

Brownian motion occurs when very small particles suspended in the fluid, seen under a microscope, appear to follow a zigzag trajectory of a totally random nature. Usually a phenomenon in science is not named for one who merely observes it, but is reserved for the...
In physics, what is the difference between a gas and a vapor?
By: Santi Meintjes
Firstly, although the words may be used interchangably by the average non-scientist person, there seems to be agreement in the scientific literature that gases and vapors are definitely not the same thing. For example, there is such a thing as a “gas-vapor phase equilibrium&rdquo...
In physics, what is the difference between a gas and a vapor?
By: Kimberly Napier
The words vapor and gas are used interchangeably throughout science. In fact physically and chemically, there is no difference. Gas is used in a more general setting, whereby the word vapor is used to talk about one certain phase of a substance. Since gas is...
In physics, what is the difference between a gas and a vapor?
By: Francis Harris
Vapor (or vapour) and gases are often used synonymously. Informally there isn't much difference between them with gas often being used as a term that encompasses vapours, and vapours being considered a particular type of gas. However, there is a technical difference that arises from...
In physics, what is the difference between a mixture and a compound?
By: Kimberly Napier
Compounds and mixtures are two scientific terms that mean two different things but yet there is confusion between the two terms. Every physical object occupies space and it has weight, or are made of matter. Matter is any object that can be touched or can...
In physics, what is the difference between a gas and a vapor?
By: John Traveler
The difference between a “gas” and a “vapor,” as the terms are used in the physics discipline, is subtle yet simple. The fundamental three states of matter “solid, liquid and gas” have been understood since antiquity, but the factors and variables...
In physics, what is the principle of moments?
By: Kimberly Napier
The principle of moment, or Varignon's Theorem, as defined by S-cool – The Revision Website, is “a force multiplied by the perpendicular distance from the line of action of the force to the pivot.” A good example to show this principle is the...
