Constants of nature
Some physical quantities in nature have a certain, fixed value that has been determined more and more precisely over the course of time. Such physical quantities are called natural constants - https://domyhomework.club . Typical examples of such natural constants are the speed of light in a vacuum as the highest possible speed that occurs in nature, the absolute zero point of temperature as the lowest possible temperature or the acceleration due to gravity, which indicates the acceleration a body has when falling in a vacuum.
Further constants of nature are z. b. the gravitational constant , Planck's quantum of action or the charge and the Mass of an electron.
Unit intentions
Every physical quantity is measured in a specific unit, e.g. B. the length in meters or the time in seconds or minutes. However, it often makes sense to specify a certain physical quantity - domyhomework.club/engineering-homework/ - in multiples or in parts of the unit concerned so that the numerical values do not become too large or too small. To do this, one uses resolutions in front of the units.
These resolutions are internationally agreed - domyhomework.club/engineering-homework/ . So has z. For example, the prefix "Extra" (abbreviation k) the importance 1000. One kilogram are 1000 grams The prefix "milli" (abbreviation m) has the meaning of a thousandth: One milligram are a thousandth of a gram. By means of a header in front of a Unit you get multiples or parts of the unit concerned.
