Fundamental and Derived Quantities

The video tutorial by Miss Rocket introduces the concept of physical quantities, which are expressed as a value with a unit. It distinguishes between fundamental quantities, which are basic and cannot be expressed in other terms, and derived quantities, which are combinations of fundamental quantities. The tutorial covers the seven fundamental quantities in the International System of Units (SI) and provides examples of derived quantities like speed, area, and volume. The video aims to help viewers understand how these quantities are used in everyday measurements.
