The mass of an object is a
measure of its inertia. The mass
of an object is constant and
does not change from place to
place.

Mass of an object remains the
same everywhere but weight of
an object changes from place
to place. For an object of mass
m weight W is dependent on
value of g.

Understanding the concepts of mass, weight,
thrust, pressure, and gravitation.

The normal force acting on a
surface, due to the weight of an
object placed on the surface, is
called ‘thrust’. As thrust is a sort
of force hence its SI unit is “a
newton” (N).

Fluid is that state of matter
which can flow. All liquids and
gases are fluids. As fluids have
weight, they exert pressure on
the base and the walls of the
container in which they are
kept.

Gravitation is a natural force
that makes every object in the
universe pull on every other
object. This pulling force is
called the force of gravitation.
