All quantities in terms of which laws of physics are expressed and which can be measured directly and indirectly are called Physical Quantities. They are of two types;
1. Fundamental Quantities: These are the quantities which are independent of each other.
There are seven fundamental quanties;
a.) Time
b.) Electric Current
c.) Temperature
d.) Luminous Intensity
e.) Amount of substance
2. Derived Quantities: These are the quantities which can be derived from fundamental quantities.
Example: Velocity, Acceleration, Momentum etc.
