Curriculum Statement
Pupil
develop factual knowledge, conceptual knowledge and procedural knowledge regarding
the topic and its role in our daily life through observation, discussion,
experimentation and evaluation by questioning and participating in practical
work and group discussion.
Content Analysis
Terms: Acceleration
Facts:
v The
velocity of a departing train from the station goes on increasing.
v When
both magnitude and direction changes acceleration will be there.
v The
velocity of a train approaching the station decreases gradually.
v The
unit of velocity is m/sec.
v The
unit of time is sec.
Concept:
v The
rate of change of velocity is acceleration. Unit-m/sec2.
v Negative
acceleration is termed as retardation.

Presentation
of the Problem
Distance and displacement are
brothers. Their common friend is time. Speed is the friend of distance and
time. Velocity is the friend of
displacement and time. They all met in a party. There comes acceleration and
here begins their likely conversation.
Acceleration: Hey, happy to see you all here.
Distance: Hii, how are you?
Acceleration:
Fine, hey look you and displacement are looking almost same. Are you both related?
Distance:
Yes he is my brother. Actually he is the measure of change of position of an object
in a particular direction.
Acceleration: Oh,
that means you both have same unit i.e. metre.
Displacement: yes,
Actually we look almost same but we are different in calculation. But in one
situation we both read the same. Can you guess it?
Acceleration: If an object travels in a straight line
then distance and displacement will be the same, isn’t it?
Distance:
Meet our common friend time.
Acceleration: I
know him, Iam also his friend.
Displacement:
Meet velocity, he is time’s and my friend.
Velocity:
Hii, acceleration.
Acceleration:
oh, so you are displacement in unit time.
Velocity:
Yes, and my unit is m/sec.
Distance:
Also Time and me have a friend, speed. Meet him.
Speed:
Nice to meet you acceleration.
Acceleration: Oh,
so you are distance in unit time
Speed:
Yes, and my unit is m/sec.
Acceleration:
So, like distance and displacement, speed and velocity looks same.
Speed:
Yes actually we are related to each other.
Acceleration: And the truth is that I also have some
relation with you, isn’t it velocity?
Velocity:
Yes, you are the rate of change of velocity.
Acceleration:
hmmm…. My unit is m/sec2.
Speed:
What is change in velocity, I can’t understand?
Velocity:
That is Final velocity-initial velocity.
Distance:
So, there is a possibility of change in velocity, isn’t it?
Acceleration: Yes
if the final velocity is less than initial velocity then it is retardation.
Speed:
is there any chance to see you both?
Acceleration: It
is difficult but when a train
approaches a station , velocity decreases at the time I becomes Retardation,
and when the train departs from the station, velocity increases and I becomes
acceleration.
Speed:
So your look changes according to changes occur.
Acceleration:
yes.
Distance:
So, we all are related to each other and hence we form a family isn’t it?
Acceleration:
Yes, so, our family name is “motion”.
All of them: so,
we all come under the same family. That is “Motion Family”.
Teacher asked the students, does
