Study Notes
- Fundamentals physical magnitudes include length, mass, time, electric current intensity, temperature, light intensity, and amount of chemical substance.
- Units of measurement for these fundamental magnitudes: length in meters (m), mass in kilograms (kg), time in seconds (s), electric current in amperes (A), temperature in kelvin (K), light intensity in candela (cd), and amount of substance in moles (mol).
- Derived magnitudes include velocity (m/s) and density (kg/m³).
- Standard units for length are the meter, with additional units like kilometer, hectometer, decameter, decimeter, centimeter, and millimeter.
- The utility of these relationships lies in the ability to convert between units, for example, from kilometers to meters or vice versa.
- Transformation examples: 4 kilometers to meters = 4,000 meters, 8,500 meters to kilometers = 85 kilometers.
- There are scalar and vector magnitudes. Vector magnitudes have magnitude, direction, and sense (e.g., displacement, velocity, acceleration).
- Scalar magnitudes include distance, mass, volume, area, temperature, pressure, energy, time, density, and frequency.
- Scalars are represented by a single value and do not require direction or sense.
