Mass, according to the University of Memphis, is the amount of matter in a given sample, while volume is the physical size of the sample. Mass and volume are two of the most important physical characteristics of matter w... More »

When explaining a Newton, the kids must be told it is an SI Unit of measurement, from the International System of Units, which are an internationally recognized standard. After that, the concept of force has to be explai... More »

The mass-energy equivalence equation, popularly known as E=mc^2, was a part of Albert Einstein's theory of special relativity. It gives the relation between energy and mass and suggests that energy can be converted to ma... More » Science Physics Motion & Mechanics

Mass is equal to density times volume, or m = Dv, since density is equal to mass divided by volume, or D = m/v. Mass is denoted by the symbol "m," and its SI units are kilograms. More »

A gram is a measurement of mass, or the amount of matter something contains, and a teaspoon is a measurement of volume, or the amount of space something takes up. Therefore, it isn't possible to precisely convert teaspoo... More » Science Measurements

The mass of an object is the amount of matter it contains while volume is the amount of space it takes up. Mass should not be confused with weight, which is the measure of the gravitational force on an object. More »

Anything that has mass and volume is called matter. There are four classical states of matter: solid, plasma, liquid and gas. Each type of matter has different properties. More »
