- About This Book
This is a list of common physical constants and variables, and their notations. Note that bold text indicates that the quantity is a vector.
The first table lists the fundamental quantities used in the International System of Units to define the physical dimension of physical quantities for dimensional analysis. The second table lists the derived physical quantities. Derived quantities can be expressed in terms of the base quantities.
12 maj 2023 · Micro (Greek letter μ (U+03BC) or the legacy symbol µ (U+00B5)) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning “small”. The symbol for the prefix is the Greek letter μ (mu).
A list of physical constants that you will need to finish some of the computation problems in this book.
Two commonly used systems of units are English units and SI units. SI units are a metric system of units, meaning values can be calculated by factors of 10. The SI base units of length, mass, and time are the meter (m), kilogram (kg), and second (s), respectively.
Describe how SI base units are defined. Describe how derived units are created from base units. Express quantities given in SI units using metric prefixes. As we saw previously, the range of objects and phenomena studied in physics is immense.
