What is unit system ? Write different types of system of units.
To describe natural and man made events around us many concepts are required. These concepts are called quantity.
There are two types of unit.
$(1)$ Fundamental quantity: Minimum number of quantities which are independent of each other and by using these quantities any event can be described are called fundamental quantities.
E.g. : length, mass and time.
$(2)$ Derived quantity : Quantity which are obtained by using fundamental quantity are called derived quantity.
E.g. : velocity, acceleration, force, work, power.
