Study Notes
Quantity and Measurement
- A quantity is a property that exists as a magnitude or size, and can be measured by asking "how much" or "how many".
- Examples of physical quantities include length, mass, time, area, and volume.
- Physical quantities are measurable, unlike non-physical quantities like love, affection, and sadness.
- Classification of physical quantities is into three types:
Fundamental Physical Quantities
- Defined as physical quantities that are independent of other physical quantities.
- Examples of fundamental physical quantities are not provided in the text.
Derived Physical Quantities
- Not explicitly defined in the text, but are likely to be physical quantities that are derived from fundamental physical quantities.
Supplementary Physical Quantities
- Not explicitly defined in the text, but may be an additional categorization of physical quantities.
