Distinction of Newton's First law and Galileo's Assertion

PRAYER
•Dear Lord and Father of all, Thank you for
today. Thank you for ways in which you
provide for us all. For Your protection and
love we thank you. Help us to focus our
hearts and minds now on what we are about
to learn. Inspire us by Your Holy Spirit as we
listen and write. Guide us by your eternal
light as we discover more about the world
around us. We ask all this in the name of
Jesus. Amen.

LEARNING IS FUN AND WILL
BE MORE MEANINGFUL IF:
• Maintain physical distancing
• Sanitize your hands as often as you can
• Participate in all the activities
• Enjoy the lesson
• Let us learn together
PRE- ACTIVITY

DIRECTIONS: COMPARE AND CONTRAST THE DIFFERENT IDEAS
OF ARISTOTLE AND GALILEO THAT PAVED THE WAY IN THE
DEVELOPMENT OF THE FOUNDATION OF OUR UNDERSTANDING
OF MOTION.
ELICIT: LET’S REVIEW!
ARISTOTLE
GALILEO
DIFFERENCES DIFFERENCES
SIMILARITIES
MOTION

LEARNING OBJECTIVE:
•Explain the subtle distinction between
Newton’s 1st Law of Motion (or Law of
Inertia) and Galileo’s assertion that force
is not necessary to sustain horizontal
motion
(S11/12PS-IVd-51)

1.Which one is easier to pull the cloth out without moving the
bottle? Why?
2.Which between the bottles has greater resistance to motion?
3.How is mass related to inertia? Explain your answer.
ENGAGE: KEEP ME
STANDING
GUIDE QUESTIONS:
PERFORM A SIMPLE
EXPERIMENT SHOWING
INERTIA AND STRICTLY
FOLLOW THE
PRECAUTIONS.

The Coin Flip Experiment
EXPLORE: PRESENTING
EXAMPLES OF THE NEW
LESSON.
Guide questions:
1. What will happen with the
coin if you quickly pull the
card? Explain your answer.
2. If you will pull the card
slowly, do you think you will
get the same result? Justify
your answer.

1. According to Galileo, how do objects maintain its
horizontal motion?
2. State Newton’s first law of motion. What makes the
object remain in state of motion or at rest? explain why?
3. Explain the difference on Galileo’s idea of inertia and
Newton’s first law of motion.

NOTE: WHILE THE VIDEO IS BEING PLAYED PLEASE LISTEN CAREFULLY SO YOU CAN
TAKE NOTE OF THE KEY POINTS
EXPLAIN: DISCUSSING NEW CONCEPTS AND PRACTICING NEW SKILLS

GUIDE QUESTIONS #1
GALILEO BELIEVED
THAT AN OBJECT IN
MOTION, IF UNIMPEDED,
WILL CONTINUE TO BE IN
MOTION; AN EXTERNAL
FORCE IS NOT NECESSARY
TO MAINTAIN THE
MOTION.
-WHEN NO FORCES
RESIST IN THE MOVEMENT

DEVELOPING MASTERY
LIGHTS, INERTIA, FRICTION!
PERFORM A DEMONSTRATION SHOWING INERTIA &
FRICTION THROUGH:
a)role play
b)reporting/talk show
c) dancing/singing
*they can use any language like Tagalog, Waray or
English which will help them express their ideas
more clearly.

CASE ANALYSIS
Cardo bought a second hand Toyota Vios car as a gift for himself
on his birthday. With so much excitement, he immediately drove
the car at a minimum speed just to be safe. As he was driving,
her fiancée called which suddenly distract his attention. With him
focusing on the phone, he didn’t see that someone is already
walking across the road which led him to step fully on the break.
This incident led him to a minor head injury because he bumped
in the front shield of his car. According to the police report, he
forgot to follow an important precautionary measure when
driving.
ELABORATE: Finding Practical Applications

GUIDE QUESTIONS:
1. What violation does he most likely
committed aside from using his phone while
driving?
2. Why did he bump on the front shield?
Justify your answer by integrating the Law of
Inertia.

DIRECTIONS: USING A THREEFOLD FRAYER DIAGRAM,
ANSWER WHAT IS BEING ASKED IN EACH BOX BELOW.
BE CONCISE WITH YOUR ANSWERS.
•Using the accomplished
frayer diagram explain the
subtle distinction between
Newton’s 1st Law of Motion
(or Law of Inertia) and
Galileo’s assertion that force
is not necessary to sustain
horizontal motion.

EXTEND: BE INSPIRED
• Create an Acrostic Poem or song now that you have understood
the law of inertia, using the word INERTIA. In creating your poem,
you may share what you have learned or experienced facing the
COVID-19 pandemic or any experience at home or in the community
or get an inspiration from your friends’ experiences by asking some
information regarding his/her experiences.
