This is a lesson about distance and displacement. activities are provided. Distance is the measure of “how much ground an object has covered during its motion” while displacement refers to the measure of “how far out of place is an object.” In this article, let us understand the difference between distance and displacement.
What Is Distance?
Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
Let’s understand the concept of distance with the help of the following diagram:
Boy cycling his way back home from a reference point A crossing point C to get to point B
Explanation of distance
Distance here will be = 4m + 3m + 5m = 12 m
Distance Formula
How is Displacement defined?
Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position. For example- If an object moves from A position to B, then the object’s position changes. This change in the position of an object is known as Displacement.

34. Distance is the length of the path
taken by an object whereas
displacement is simply the distance
between where the object started and
where it ended up.

by magnitude only?
2. What do we call the shortest distance between the object’s initial and
final position specified by both magnitude and direction?
3. How is it possible for displacement to be equal to distance?
4. Is it possible for displacement to be greater than distance? How will
you explain your answer?

72. SITUATION: DJ was asked by his mother to
buy a gallon of ice cream. From home he
headed north towards store 1, but
unfortunately no ice cream was available, so
he decided to go to another store which is three
blocks away from the first store. Fortunately,
there was an available ice cream in store 2. DJ
was having a hard time to decide on which
path would he use to go back home to avoid
ice cream from melting.

longest distance?
A. AFE
B. ABCDE
C. AE
D. AC
75. 3. Analyze the picture of the map, which

D. 28m
77. 5. Based on the situation, how will you differentiate distance
and displacement?
A. Distance is a vector quantity while displacement is a scalar
quantity.
B. Distance is the total length traveled by an object while
displacement is a scalar quantity.
C. Distance is a vector quantity while displacement is the
shortest distance traveled from initial to the final position.
D. Distance is the total length traveled by an object while
displacement is the shortest distance traveled from initial to
the final position.
79. Now that you have
the idea about
distance and
displacement, give
real-life situations
showing the
difference between
distance and
displacement.

81. This picture demonstrates the real-
life example, that there are two paths
in our life to reach our destination,
one is a shortcut and another one is
hard work. The majority of people
choose the first one called the
shortcut, and get tangled for the rest
of their lives, but the one who
chooses hard work, reaches his
destination faster than others.
Initial barriers are just like a closed
door which we don't prefer to break,
instead entering into an open door to
make our life more challenging. It's
never too late to implement it, now
it's up to you what you choose.
