What i the difference between fundamental and derived quantities?

- Fundamental quantities are quantity whose definition does not depend on other quantities.

There are seven fundamental quantities in physics:

Length (measured in metres)

Mass (in kilograms)

Time (in seconds)

Electric current (in Ampere)

Temperature (in Kelvin)

Amount of substance (in moles)

Luminous intensity (in candela)

- On the other hand, derived quantities are quantities that are defined using the fundamental quantities.

For example, derived quantities are:

Velocity, which is the ratio between length and time

Acceleration, which is the ratio between velocity and time

Energy, which is a product of mass and velocity squared

And many others.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
