A derived quantity is a physical quantity that is calculated from one or more base quantities using mathematical operations or relationships. Derived quantities are not independent but are derived from the base quantities through equations or formulas. Examples of derived quantities include velocity, acceleration, force, energy, and power.

Derived Quantity
A derived quantity is a quantity that is defined in terms of other, more fundamental quantities. It is obtained by multiplying, dividing, or taking the power of fundamental quantities.
Example:
Speed is a derived quantity that is defined as the distance traveled per unit time. It is obtained by dividing the distance (fundamental quantity) by the time (fundamental quantity).
Other Examples of Derived Quantities:
- Volume (length x length x length)
- Density (mass / volume)
- Force (mass x acceleration)
- Energy (force x distance)
- Power (energy / time)
Characteristics of Derived Quantities:
- Derived quantities do not have their own fundamental unit.
- They are expressed in terms of the units of the fundamental quantities used to define them.
- They have units that depend on the units chosen for the fundamental quantities.
Importance of Derived Quantities:
Derived quantities allow us to describe and quantify various aspects of the physical world in terms of more fundamental quantities. They provide a convenient way to express and manipulate physical relationships.
