What are fundamental quantities, and can you provide two examples?
Fundamental quantities are basic physical quantities that cannot be defined in terms of other quantities. Examples include length and mass.
Explain what a derived quantity is and give an example.
Explain what a derived quantity is and give an example.
A derived quantity is a physical quantity that is defined in terms of fundamental quantities. An example is velocity, which is derived from length and time.
Why is it important to have standard units of measurement?
