Scalar quantities are those that have magnitude but no direction. Here are some common examples of scalar quantities:
1. **Temperature**: Measured in degrees Celsius, Fahrenheit, or Kelvin.
2. **Mass**: Measured in grams, kilograms, etc.
3. **Distance**: The total length between two points, measured in meters, kilometers, etc.
4. **Speed**: The rate at which an object covers distance, measured in meters per second (m/s), kilometers per hour (km/h), etc.
5. **Time**: Measured in seconds, minutes, hours, etc.
6. **Energy**: Measured in joules, calories, etc.
7. **Work**: Also measured in joules.
8. **Power**: Measured in watts.
9. **Volume**: Measured in liters, cubic meters, etc.
10. **Density**: Mass per unit volume, often expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
These quantities are fully described by their numerical values alone, without needing to specify a direction.
