# Fundamental Physics/Matter

## Defintion

Matter represents any physical quantity that can be measured and observed for example, a ball, a molecule, an atom ...

## Matter's Characteristics

All matter exists in 3 states Solid, Liquid, Gas . Ex, ice cube exists in solid, water exists in liquid, water vapour exists in gas . All matter has a mass denoted in M which indicates quantity of matter's material and a volume denoted as V which indicates matter material's container . The ratio of mass over volume gives density of matter's material

${\displaystyle D={\frac {M}{V}}}$

With

Mass indicates matter's quantity . Mass is denoted as M measured in unit Kg
Volume indicates matter's size . Volume is denoted as V measured in unit m3
Density indicates matter's quantity over its size . Density is denoted as D measured in unit Kg/m3

## Scientific measurement unit of measuring mass

 Kilo K ${\displaystyle 10^{3}=1,000g}$ Mega M ${\displaystyle 10^{6}=1,000,000g}$ Pico P ${\displaystyle 10^{9}=1,000,000,000g}$
