In the language of measurement, 'dimensions?' are measurable attributes of reality such as 'time', 'distance?', 'velocity', 'mass', 'weight', and so on.

Traditionally, the accepted fundamental dimensions are mass, length, time, and temperature, but in principle, other fundamental dimensions could be used.

This system is considered by the System of Units made by

fundamental ones.

Velocity, for example, is length divided by time, and so can be generated from the above list of fundamental dimensions.

Traditionally, the accepted more used fundamental dimensions are

:
# mass,
# length,
# time,
# and electric current,

but, the other

3

fundamental dimensions can also be used for more complex physics problems:

# ([thermodynamic temperature]?,
# [amount of substance]?,
# [luminous intensity]?).

Velocity, for example, is length divided by time, and so can be generated from the above list of fundamental dimensions.

Physics call velocity a [derived dimension]?.

In the language of measurement, 'dimensions' are measurable attributes of reality such as 'time', 'distance', 'velocity', 'mass', 'weight', and so on.

A system of Fundamental dimensions is such that every other dimension can be generated from them. Traditionally, the accepted fundamental dimensions are mass, length, time, and temperature, but in principle, other fundamental dimensions could be used.

Velocity, for example, is length divided by time, and so can be generated from the above list of fundamental dimensions.
