Question

What are physical quantities areas and forced derived quantities

Answer 1

Answer:

Derived quantities : The quantities, which can be expressed in terms of the fundamental quantities are called derived quantities. For example volume, velocity, Pressure etc. Derived Units : The units of all other physical quantities, which can be obtained from fundamental units, are called derived unit.

==>Derived quantities : The quantities, which can be expressed in terms of the fundamental quantities are called derived quantities. For example volume, velocity, Pressure etc. Derived Units : The units of all other physical quantities, which can be obtained from fundamental units, are called derived unit.

Explanation:

==>Mass, Length & Time are fundamental physical quantity while velocity is derived physical quantity.

==>What are examples of derived quantities?
