Competency: Compare and contrast the Aristotelian and Galilean conceptions of vertical motion, horizontal motion, and projectile motion. S11/12PS-IVc-46
Explain how Galileo inferred those objects in a vacuum fall with uniform acceleration, and that force is not necessary to sustain horizontal motion.

lV. Procedure
a. Activity /
Preparation
Activity 1.1 Guide Questions:
1. Who were the Ancient Greek
Astronomers who studied the
motion of heavenly bodies from
Aristotle to the year 200 AD?
2. Who were those Astronomers
who made contributions to the
study of heavenly bodies from
1400 to the time of Galileo
Galilei?
3. Do you think that our current
understanding of the physics of
motion happened overnight?
Support your answer.
Picture Analysis:
What makes the ball keep on rolling? What makes the pins fall in
different directions?
Guide Questions:
1. Which falls first, the heavier or
lighter object? Defend your answer.
2. What is the role of air resistance
here?
Downloaded by Jezel Ocba (jezelgocba@gmail.com)
Guide Questions:
1. What keeps an object at rest and what keeps it moving?
2. What causes the object to change in motion?

4. What do think were the bases of
the different astronomers or
natural philosophers in their
explanations of motion?
1. Abstraction
(discussion)
3. What is the impact of this activity
to you?
Lecturette on the Key Concepts
The teacher will present a video
about the Aristotelian and Galilean
Conceptions of Vertical Motion,
Horizontal Motion, and Projectile I. Aristotle's View of Motion
Motion
https://www.youtube.com/watch? II. Galileo's View of Motion
v=IhlNv9FTikU
3. How does an object’s mass affect its inertia?
Lecturette on the Key Concepts
I. Galileo and Inertia

Galileo's Experimentation to prove
his

Ideas about motion.

 Experiment I

 Galileo dropped two different
weights of a cannonball into the
Leaning Tower of Pisa and they fell
at the same time but could not
measure the distance traveled
therefore he proceeded to another
experiment.
Experiment II
 Galileo used the inclined ramp in
order to measure the acceleration of
an object. He used a rolling ball to
measure the changes. He measured
those objects’ accelerates at the same
time regardless of their size and
mass.
Downloaded by Jezel Ocba (jezelgocba@gmail.com)
Developed the concept of
motion in terms of
velocity (speed and
direction) by using
inclined planes.
Developed the idea of a
force that causes motion.
Determined that the
natural state of an object is
rest or uniformed motion.
Developed the idea that
objects resist motion and
inertia.

II. Isaac Newton and his First Law
of Motion
An object at rest stays at rest and
an object in motion stays in
motion with the same speed and
in the same direction unless acted
upon by an unbalanced force.
The teacher will present a
supplementary video on the First
Law of Motion.
https://www.youtube.com/watch?
v=LEHR8YQNm_Q
Guide Questions:
1. What is the First Law of
Motion?
2. Describe inertia.
3. Compare balance forces and
unbalanced forces.
4. Explain the friction of force.
lOMoARcPSD|16828582
 Speed is the distance traveled by
an object divided by the time taken
to travel the distance.
 A ball rolling down an inclined
plane increases its speed by the same
value after every second
2. Application /
Practice
Mini Lab: Aristotle or Galileo?
Test the following activities
below. Take note that in every
activity, both objects should be
dropped at the same time and at
the same height. (In choosing the
height, be sure that you are safe).
1. Drop a book and a flat sheet of
paper.
Activity 1.3 Critical Writing
Answer the questions briefly.
1. State Newton’s first law of motion. What makes the object remain in
the state of motion or at rest? Explain why?
2. Explain the difference between Galileo’s idea of inertia and
Newton’s first law of motion.
2. Drop a book and a sheet of
paper crumpled into a ball.
3. Drop a book with a small flat
sheet of paper on top of it.
3. Assessment /
Evaluation

4. Assignment /
Agreement
Given two one-peso coins,
released at the same time, Coin A
is dropped while Coin B is thrown
horizontally coming from the
same height. Which one do you
think would reach the ground
first? Use a sheet of paper for your
observations.
Try it: Stemtokperiment
Create an acrostic on the word
INERTIA.
Prepared by:
This activity depends on the
availability of materials at home. Get
a basketball ball and ping pong ball.
Hold the balls on your hand, at the
height level of your shoulder, then
simultaneously drop the ball.
Observe what happens.
