,1.0 MEASUREMENT
Physics is a science based upon exact measurement of physical quantities. Therefore
it is essential that student first becomes familiar with the various methods of
measurement and the units in which these measurements are expressed.
A unit is a value quantity or magnitude in terms of which other values, quantities or
magnitudes are expressed.
1.1 FUNDAMENTAL QUANTITIES AND UNITS
A fundamental quantity also known as base quantity is a quantity which cannot
be expressed in terms of any other physical quantity. The units in which the
fundamental quantities are measured are called fundamental units. In mechanics
(study of the effects of external forces on bodies at rest or in motion), the quantities
length, mass and time are chosen as fundamental quantities.

(iii) The M.K.S (Metre, Kilogram, Second) System; and
(iv) The S.I. (International System of Units).
1.3 THE INTERNATIONAL SYSTEM OF UNITS (S.I.)
The S.I. is the latest version of the system of units and only system likely to be used
all over the world. This system consists of seven base or fundamental units from
which we can derive other possible quantities of science. They are

1.4 CONCEPT OF DIMENSION
Dimension of a physical quantity simply indicates the physical quantities which
appear in that quantity and gives absolutely no idea about the magnitude of the
quantity. In mechanics the length, mass and time are taken as the three base
dimensions and are expressed by as letter [L], [M] and [T] respectively. Hence, a
formula which indicates the relation between the derived unit and the fundamental
units is called dimensional formula.
Example 1: Deduce the dimensional formula for the following physical quantities:
(a) Velocity, (b) acceleration, (c) force, (d) pressure, (e) work, and (f) power.
