Study Notes
Measurement and Error
- Measurements quantify physical quantities, including magnitude.
- The SI (International System) unit is widely used in science.
- The fundamental units in SI provide consistency.
Basic Units
- Length: meter (m)
- Mass: kilogram (kg)
- Time: second (s)
- Electric Current: ampere (A)
- Thermodynamic Temperature: kelvin (K)
- Amount of Substance: mole (mol)
- Luminous Intensity: candela (cd)
Derived Units
- Derived units combine basic SI units for complex measurements.
- Examples include area (square meter), volume (cubic meter), speed/velocity (meters per second), and acceleration (meters per second squared).
