2 types of Physical Quantities

• Base Quantity & Derived Quantity

• Base Quantity & Physical Quantity

• Physical Quantity & Dimension Quantity

• Vector Quantity & Scalar Quantity

Basic quantity is defined as a

• quantity which can be derived from any physical quantities.

• quantity which cannot be derived from any vector quantities.

• quantity which cannot be derived from any physical quantities.

• quantity which can be derived from any vector quantities.
