Study Notes
SI Base Units
- Consist of the following fundamental units: metre, kilogram, second, ampere, kelvin, mole, and candela.
- Measure different physical quantities: length, mass, time, electric current, temperature, amount of substance, and luminous intensity.
Unit Prefixes
- Represent standard multiples and submultiples based on powers of ten (base-10) or powers of two (base-2).
- Used to simplify the expression of very large or very small measurements (e.g., kilo- for 10^3, milli- for 10^-3).
Base Unit of Measurement
- A unit that is established and standardized for a fundamental physical quantity.
- Serves as a reference point for measuring other quantities.
Derived Units
- Created from the combination of base units to express derived quantities, which are measurements resulting from physical laws or equations.
- Examples include units like newton for force, which combines kilogram, metre, and second.
Coherent Derived Units
- These units are derived such that they do not require conversion factors when expressed in terms of base units.
- Maintain consistency and clarity in scientific communication, ensuring straightforward relationships among quantities.
