Study Notes
Physical and Non-Physical Quantities
- Physical quantities can be measured using instruments. Examples include:
- Mass
- Length
- Time
- Current
- Non-physical quantities cannot be measured. Examples include:
- Feelings
- Emotions
Measuring Physical Quantities
- Measurement compares a physical quantity to a basic reference standard, called a unit.
- Common units include 1 meter (m), 1 kilogram (Kg), and 1 second (s).
- Expressing a measurement requires both:
- Unit
- Magnitude (value) of the quantity - how many times the unit is contained in the quantity
- Physical Quantity (P.Q) = Magnitude (m) × Unit (u)
