Rolling motion of rigid body
The mks units of these derived quantities are, therefore, the corresponding combinations of the mks units of length, mass, and time. For instance, a velocity can be reduced to a length divided by a time. Hence, the mks units of velocity are meters per second
In addition to the three fundamental quantities, classical mechanics also deals with derived quantities, such as velocity, acceleration, momentum, angular momentum, etc. Each of these derived quantities can be reduced to some particular combination of length, mass, and time.
Here, p stands for a momentum, and M for a mass. In this manner, the mks units
of all derived quantities appearing in classical dynamics can easily be obtained.
Volume =[L3] (m3)
Density = [M]/[V] = = [M]/[L3] (kg/m3)
Additional non-standard units of length include the inch (1 ft = 12 in), the yard (1 ya = 3 ft), and the mile (1 mi = 5280 ft). Additional non-standard units of mass include the ton (in the US, 1 ton = 2.000 lb; in the UK, 1 ton = 2240 lb), and the metric ton (1 tonne = 1000 kg). Finally, additional non-standard units of time include the minute (1 min = 60 s), the hour (1 hr = 3600 s), the day (1 da = 86400 s), and the year (1 yr = 365.26 da = 31558464 s).
