Units & Measurements in Basic Science
- S.I. unit of acceleration is meters per second squared (m/s²).
- Derived quantities are formed from fundamental quantities, such as m/s (velocity) and N (Newton for force).
- Joule is the unit of energy, often represented as option C in related questions.
- A standard used to measure a physical quantity is known as a unit.
- Measurement requires both a numerical value and a unit for accurate representation.
- There are two main types of units: fundamental units and derived units.
- Kelvin is the unit of temperature, fundamental in thermodynamics.
- Derived quantities depend on two or more fundamental quantities for their definitions, such as force (N) being derived from mass (kg) and acceleration (m/s²).
