1. Drill
This morning, let’s start our day with a group
activity called “Make me a Collage”. I have here a
set of cut out pictures that you will have to
arrange accordingly to form a certain image. The
group who finished first will be the winner.
Are you ready?
Yes ma’am.
Okay, this is the group 1, group 2, and group 3.
Please go to your respective groups so that I can
distribute now these cut pictures.
(The students form a circle and start their work).
Great Job class!
Now, the winning group is the group 1. Let’s give
them a fireworks clap.
2. Review
Class, what was your topic last meeting?
It was all about ecosystem ma’am.
Very good! And what is ecosystem all about?
Ecosystem is a community of living and non-
living things interacting with each other in a
specific environment.
Excellent! Now, what are those types of the
ecosystem?
Terrestrial ecosystem
Aquatic ecosystem
Man-made/Artificial Ecosystem
Exactly correct! How about the ecological
relationship?
There are two types of ecological relationships
and these are the symbiotic relationship which
includes mutualism, commensalism, parasitism,
predation, and competition. Other type of
ecological relationship is the oppositional
relationship.
Very well said! I’m great that you still remember
all of those.
B. Developmental Activities
1. New lesson
a. Motivation
This time, let’s move on to our new lesson.
A girl is running.
What is in the picture?
A girl, the group of friends, and the house
Very good! So, what can you say about the ma’am.
picture?
You are correct! And why do you think she run A girl is running from the house ma’am.
from the house?
Exactly! Where did she run into? Because she wants to play with her friends
ma’am.
Very good! Now, in your own experience, how far
you go with your friends to have time together? She run to the outside ma’am.
That’s great to know. How about the others? Not just that so far ma’am, but I still have to ride
a vehicle to play and have some talks with them.
Okay, that’s good that you have less hassle in It’s easy for us ma’am to play with them because
times that you want to be with them. we are closely living with our houses.
Now, how long would you usually have time with
your friends? Isn’t it whole day, or most of the
time only?
Okay, I agree with that since you are altogether Whole day ma’am since we are in the school and
with them all the time. we can still communicating through social media.
2. Presentation
Now class, our lesson for today is all about
motion in one dimension which includes the basic
concept of motion, speed, time, and velocity.
Later, we will know each one of them.
2.1 Setting of Standards
Class, I want you to activate the classroom rules.
Okay ma’am.
So, what will you do if someone is talking in front
of you?
Listen, participate, behave and show respect to
others, ma’am.
Okay, you must all listen, participate, behave and
show respect to others especially to the one who
is talking in front of you.
Can I expect all of that from you class?
Yes ma’am.
Good to hear that. So, please sit properly, listen
and eyes on here.
3. Discussion
Now class, what word you can associate to
motion?
Movement
Force
Position
Changes
Very good! Those words are definitely associated
with motion. Now, kindly read its definition.
Motion is the change in position for a particular
time interval. If a body has changed its position,
we can say that it has moved with respect to its
original position.
Okay, motion is a fundamental concept in physics
that refers to the change in position of an object
over time. Basically, it concerns to the starting
point and final point of where the object goes
along. It has something to do with speed, velocity,
acceleration, and displacement. Later on, we will
know more about this. But now, kindly read this
one.
Thus, the original position serves the reference
point.
So, in this picture, there is a motion happens
because the bicycle moved from its reference
point up to its final position. Now, what is
reference by the way? Please read.
Reference point is a place or objects used for
comparison if something is in motion. Object
must be fixed relative to earth, such as: building,
tree, or a sign.
Meaning class, reference point refers to the
original position of an object. Going back to the
last picture, the reference point there is in the
road where the biker is started to ride. An object
may be moving with respect to another
reference. For example, when you are inside the
bus, you are not moving with respect to the other
passenger, but you are moving with respect to
the ground. In addition, kindly read.
Motion can be described by measuring the total
length of path travel by an object, and by
measuring the distance between the initial and
final position of the object.
This is the sample concept of initial position to
final position. As you can see here, the initial
position covered 100 meters and so with the final
position. But, in getting the total length of path
travelled, simply add the length of travelled from
A, B, to C, and C to D. That is why the total length
here is 250 meters.
Did you understand class?
Yes ma’am.
That’s great! Kindly read everyone.
The length of the entire path that the car
travelled is referred to as distance. This means
that the distance travelled by the car is 250
meters.
Now class, do not be confused with the total
length carried by object because it’s just simply
referred to the distance covered.
Now, let’s move on to the displacement. Please
read.
Displacement is the shortest distance between
the object’s initial and final positions. See
illustrations above. Based on the given
illustration, the displacement is 50.
So class, what is the difference of the distance
and displacement?
Distance is the length of the path taken by an
object whereas displacement is the simply the
shortest distance between where the object
started and where it ended up.
Very good! Let’s have another example of
displacement. Above scenario illustrates a car just
go back to its original or initial position?
In this case, since the initial and final positions are
both 100 meters away, and we don't know the
direction of the motion, we cannot determine the
displacement with the information given.
If the motion was in a straight line, the
displacement would be equal to the distance
traveled, which is also 100 meters. However, if
the motion involved changes in direction, the
displacement could be less than 100 meters.
Therefore, without more information about the
direction and path of the motion, we cannot
determine the displacement.
Now, let’s tackle about speed. Please read.
Speed refers how fast or slow an object travel.
But class, remember that we can have a higher
value of speed if there is a wide distance covered
by an object. Example, an airplane travels 800 km
in 1 hour and a car travels 80 km in 1 hour. What
is the difference of the two?
The difference between the two is their speed or
velocity, which is the rate of change of position
with respect to time.
Very good! The speed of the airplane is 800
km/hour, and the speed of the car is 80 km/hour.
Therefore, the difference in their speeds is:
800 km/hour - 80 km/hour = 720 km/hour
This means that the airplane is traveling 720
km/hour faster than the car.
IN addition, most vehicle cannot maintain
constant speed overtime. In this case we will use
the term, average speed.
To find average speed this is the formula:
Average speed = total distanced
elapsed time
s=d
t
Everybody, please read the key terms.
Speed is the rate at which distance is covered
overtime.
Average speed is the rate at which the total
distance varies with the total time taken.
Instantaneous speed is the speed at an instant or
at a point on the path.
Excellent! To elaborate more, speed is the general
term used to describe how fast an object is
moving, while average speed and instantaneous
speed are specific types of speed that describe
the overall motion and instantaneous motion of
an object, respectively.
Now, let’s proceed to velocity. Kindly read.
Velocity refers to the speed of an object with
direction.
The formula of velocity:
Average velocity = displacement
elapsed time
v=d
t
Example:
v=d
t
v= 80km
2 hrs
v= 40 km/hr
v= 40 km/hr to the east
Please read this one.
Velocity is the speed of an object in a particular
direction.
Average velocity is the distance travelled in a
particular direction per unit time.
Instantaneous velocity refers how fast or slow an
object is moving at a given instant and in what
direction.
In short, velocity is the general term used to
describe both the speed and direction of an
object's motion, while average velocity and
instantaneous velocity are specific types of
velocity that describe the overall motion and
instantaneous motion of an object, respectively.
Now, let’s proceed to acceleration. Kindly read.
Acceleration is the rate of change in velocity of a
moving object per unit of time.
Ways to change acceleration
1. By increasing its speed while travelling in
a straight line
2. By decreasing its speed while travelling
in straight line
3. By changing its direction even while
travelling at constant speed.
Remember class that the faster the change of
velocity, the greater the acceleration.
Formula:
Average Acceleration = changed in velocity
elapsed time
a= Δ v
t
Average Acceleration = final velocity – initial velocity
elapsed time
a= vf-vi
t
Sample Problem
As a car comes to a stop, it slows from 25 m/s in
2.8 s. Find the acceleration of the car.
Given:
Initial velocity – 25m/s
Final velocity – 0 m/s (stopped)
Time – 2.8 s
a=vf-vi
t
a=0m/s-25m/s
2.8 s
a= -25m/s
2.8s
a= -8.93 m/s2
C. Concluding/ Integration Activities
1. Generalization
Again class, what is motion again?
Motion is the change in position for a particular
time interval.
Very good! And what is the difference of distance
and displacement?
The main difference between distance and
displacement is that distance refers to the total
length of the path traveled by an object, while
displacement refers to the straight-line distance
between an object's initial and final positions.
How about its formula?
Distance= speed x time
Displacement = final position – initial position
Excellent! How about the difference and formula
of speed, velocity, and acceleration?
Speed is a scalar quantity that only tells us how
fast an object is moving, while velocity is a vector
quantity that takes into account both the speed
and direction of an object's motion. Acceleration
is the rate at which an object's velocity changes,
and it is also a vector quantity.
Average speed = total distanced
elapsed time
Average velocity = displacement
elapsed time
Average Acceleration = changed in velocity
elapsed time
Very good! So much for that.
2. Valuing
Now class, why do we have to understand motion
in our life? What do you think is the importance
of it?
Understanding motion is important in our lives
for many reasons, as motion is an essential part
of our everyday experiences.
In what such ways?
Just like in transportation, motion plays a crucial
role in transportation, whether it's driving a car,
riding a bike, or flying on an airplane.
Understanding motion helps us to navigate our
way through the world, and to get from one
place to another efficiently and safely.
Perfectly said! What else?
Understanding motion helps scientists to study
and explain the behavior of objects and systems,
from subatomic particles to the movements of
the planets.
Very good! Overall, understanding motion is
important because it helps us to navigate the
world, stay safe, and solve problems. Whether we
are driving a car, playing a sport, designing a
building, or studying the behavior of the universe,
an understanding of motion is essential to our
success.
