Distance
Distance
is scalar quantity that conveys the space or
gap between one point
and
another.
Also,
it
infers
as
the
actual
length
travelled by
an
entity.
Distance is symbolized with variable ‘d’. Example:
d
=
30 meter

Mass
Weight and
mass often
interpreted as the same
matter. However, this
is
not
true,
because
mass
can
be
stated
as
an
amount
of
something (object
or
entity)
that
will
always
be
consistent
without
any
regard
of
the
forces
which applied to it. On the other hand, weight
is
mass based on gravity. For
example: a person’s mass in earth
is 60kg. Hence, the weight of this person
is 60 kg x 9.8 m/s² (earth’s gravity) = 588 N (Newton).
Vector: quantity that has both direction and magnitude
-
Displacement
Displacement (?d)
is
the
shortest
path
distance
between
two
connected
points.
Example:
A person travels
from
point
A to
D and
back
to
B.
