### Physical Quantities

Physical quantities are properties or characteristics of objects or phenomena that can be measured. Examples include length, mass, time, temperature, velocity, force, energy, and electric charge. Physical quantities can be classified as scalar or vector quantities. Scalar quantities have only magnitude, such as mass and temperature, while vector quantities have both magnitude and direction, such as velocity and force. Physical quantities are further categorized as fundamental or derived quantities. Fundamental quantities, such as length, mass, and time, are independent and cannot be expressed in terms of other quantities. Derived quantities, such as speed and acceleration, are derived from combinations of fundamental quantities.

### Importance of the Physical Quantities and Units Chapter
