Answer 2

Answer:

The foundation of physics rests upon physical quantities in term of which the laws of physics are expressed. Therefore, these quantities have to be measured accurately. Physical quantities are often divided into two categories; base quantities and derived quantities. Derived quantities are those quantities which are derived from other physical quantities. Examples of derived quantities are force, velocity, acceleration etc.
