DISTANCE AND DISPLACEMENT
In
science, motion is
defined as the change in
position for a particular
time interval. You can
then start describing
motion with the question,
“How far did the object
travel?”
How far did the object
travel?
There are actually two
question. First is by
getting the total length
of the path travelled by
Example: The dog ran 10m to the
east, then 5m to the south, and
another 10m to the west. So it has
travelled a total of 25 meters. (DRAW)
other way is by measuring
the distance between the initial
position and final position of
the object. The dog has travelled
 The
5 meters to the south.
In
science, the first
measurement gives
the distance
travelled by the
object while the
second measurement
file: Here are more
illustrations showing the
difference between distance
travelled (represented by
broken lines) by an object and
its displacement (represented
by continuous lines).
Can
you give one difference
between distance and
displacement base on the
given examples?
When can displacement be
equal to zero?
Is it possible to get zero
displacement?
 What
if the ball, the car, and the
dog in the illustration go back to
their starting positions, what will
happen to their respective
displacements?
 If you answered these questions
correctly, then you have most
probably understood the
difference between distance and
Distance
refers to the length of
the entire path that the object
travelled.
Displacement refers to the
shortest distance between the
object’s two positions, like the
distance between its point of
origin and its point of
destination, no matter what
When
a graph is plotted in terms
of the distance travelled by the
object and the time it took to
cover such distance, the graph
can be called distance-time
graph. If the graph is plotted in
terms of displacement and time,
it is called displacement-time
graph. Refer to the graph in
What
is the displacement of
the object after 2 seconds?
What is its displacement
after 6 seconds? How will
you describe the motion of
the object between 0s and
2s, between 2s and 4s, and
between 4s and 6s?
