Study Notes
Units of Measurement
- A unit of measurement adopted for a base quantity is called a base unit.
- A unit multiple is a unit that is a multiple of a base unit, obtained by multiplying the base unit by a power of 10 (e.g., kilogram, centimeter).
- A coherent derived unit is a unit of measurement that is derived from base units, and is used to measure derived quantities (e.g., velocity, force).
Base Quantities
- Base quantities are physical quantities that cannot be expressed in terms of other quantities, and are used as a reference for measurement (e.g., length, mass, time).
- Seven base quantities are recognized in the International System of Units (SI): length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.
Momentum
- Momentum is a physical quantity related to the product of an object's mass and velocity.
