ETULAY Physical Science Week 2 PowerPoint

The document discusses the contrasting views of motion between Aristotle and Galileo, focusing on their differing concepts of vertical, horizontal, and projectile motions. It highlights Galileo's experiments that led to his conclusions on motion, including the idea of inertia and the necessity of force in maintaining motion. Furthermore, it introduces Newton's first law of motion, which builds upon Galileo's ideas and addresses the concept of balanced and unbalanced forces.

The Aristotelian & Galilean Conceptions of
Vertical, Horizontal and Projectile Motions
•Motion is the
action of
changing
location or
position.

Horizontal and
vertical motion and
projectile motions
can be derived
from the
quantification of
the “RATE OF FALL”
or
“ACCELERATION”
The Aristotelian & Galilean Conceptions of
Vertical, Horizontal and Projectile Motions

According to
Aristotle, Motion is
divided into two
main classes:
• NATURAL MOTION
• VIOLENT MOTION

Vertical Motion (Aristotle)
• Vertical Motion is natural
motion
• In a natural motion,
objects move and return
to its natural state based
on its material or
composition

Vertical Motion (Aristotle)
• When a thing thrown
upward falls down, its
element was earth.
• smoke goes up in the air
because it is its natural place
• Aristotelian concept of
natural motion is largely
falling or rising

Horizontal Motion (Aristotle)
•An object moving in a
violent motion requires
push or pull to maintain
horizontal motion.

Projectile Motion (Aristotle)
•Projectile motion of an
object is parallel to the
ground until it is the
object’s time to fall
back into the ground.
• it is both natural and
violent motion

Galileo Galilei
Galileo Galilei – an Italian
physicist considered as
the “father of modern
physics”

Vertical Motion (Galileo)
• In the absence of
resistance, objects would
not fall depending on
their weight, but in the
time of fall.

Horizontal Motion (Galileo)
•An object in motion, if
unimpeded, will
continue to be in
motion, and an external
force is not necessary to
maintain that motion.

Projectile Motion (Galileo)
•Projectile is a
combination of a
uniform motion in the
horizontal direction
and uniformly
accelerated motion in
the vertical direction

Galileo’s Experimentation
• Galileo dropped
two different
weights of cannon
ball to the Leaning
Tower of Pisa

Galileo’s Experimentation
• Galileo used
the inclined
ramp to
measure the
acceleration
of an object

Galileo’s Experimentation
• Speed is the
distance
travelled by an
object divided
by the time
taken to travel
the distance

Galileo’s Experimentation
• A ball rolling down
an inclined plane
increases its speed
by the same value
after every second.
• the ball increases
speed by 2 m/s
every second

The first concepts
of laws of motion
was developed
by Galileo after
his experiments

Galileo’s and Inertia

Isaac Newton & his First Law of
Motion
Isaac Newton
expanded Galileo’s
work and came up
with his Three Laws
of Motion

Isaac Newton & his First Law of
Motion
First Law of Motion
(Inertia) – object at rest
stays at rest and object
in motion stays in
motion with the same
speed and in the same
direction unless acted
upon by an
unbalanced force.

Mass and Inertia
Mass is
proportional
to its inertia

Mass and Inertia
Which of the two is harder to
stop when running downhill?

3 types of Inertia
Inertia of Rest –
object will stay in
place unless
something moves
it.

3 types of Inertia
Inertia of Motion –
an object will
continue at the
same speed until
a force acts on it.

3 types of Inertia
Inertia of Direction
– an object will stay
moving in the same
direction unless a
force acts on it.

Forces
•Force is
defined as a
push or pull
• It is measured
in Newtons

Forces
1𝑛𝑒𝑤𝑡𝑜𝑛=1 𝑘𝑔 𝑥1𝑚/ 𝑠/ 𝑠
1 𝑛𝑒𝑤𝑡𝑜𝑛=1 𝑘𝑔 .𝑚 / 𝑠2

Friction
It is a force that opposes
motion between any
surfaces that are touching

Friction
Rough surfaces have
more friction that smooth
surfaces

Friction
Heavier objects have
more friction

Balanced and Unbalanced Forces
Balanced force occurs
when the NET FORCE is
equals to zero.

Balanced and Unbalanced Forces
Net force is the
total
combination of
forces acting
on an object

Balanced and Unbalanced Forces
Unbalanced force occurs
when the net force is
greater than zero.

Editor's Notes

#1 Magandang Lunes ng hapon sa lahat ng ating mga masugid ka tagasubaybay ng nating ETULAY sessions!! Welcome to another ETULAY session! Tutor Lester po, at your service.
#2 Nasa ikaapat na Quarter na po tayo mga ka-ETUlay We are on the First week for the Quarter. Mga paksa mula sa tatlong module po ang ating tatalakayin ngayong hapon at sana ay matalakay natin lahat sa loob ng time slot natin. Ang mga paksa po natin ngayon ay Astronomy & Examples of Astronomical Phenomena Before the Advent of Telescopes
#3 Ang mga objectives po natin ay mula po sa Most Essential Learning Competencies o MELC. (Read the competencies)
#4 Simulan po natin ang tutorial session sa isang pre-test na may limang katanungan ko lamang.
#12 Ang discussion natin ngayong lingo na ito ay naka sentro sa PAGGALAW o motion. Motion is (read the slide) Hindi lang astronomy ang pinag-aralan ng mga sinaunang Griyego o Greeks. Pinag-aralan din nila ang paggalaw o MOTION. Ang kaalaman natin sa MOTION ay nabuo sa loob ng mahabang panahon. Nagsimula ito nang pag-aralan ng mga PHILOSOPHERS ng Sinaunang Greece kung bakit nangyayari ang MOTION.
#13 When scientists were finally able to quantify or measure the RATE OF FALL or acceleration, it was there that we finally understood the physics of motion. We will compare the concepts of motion by done by PHILOSOPHY VS. SCIENCE in the person of ARISTOTLE and GALILEO. Ating simulan sa concepts ni Aristotle na isang PHILOSPHER
#14 Ayon kay Aristotle, there are two main classes of motion which are the following: NATURAL MOTION AND VIOLENT MOTION.
#15 Ayon sa konsepto ni Aristotle ang vertical motion ay isang NATURAL motion. Sa isang natural motion gumagalaw ang isang bagay at bumabalik sa kanyang NATURAL STATE ayon sa material kung saan gawa ang isang bagay.
#16 Kapag bumabalik sa lupa ang ibinato natin paibabaw, ang ibinato natin ay gawa sa lupa. Ang usok naman ay lumilipad dahil nasa kalangitan ang pinaggalingan nito. So mostly the concept of natural motion by Aristotle is focused on falling or rising which is the vertical motion.
#17 Ang horizontal motion naman according to Aristotle is a VIOLENT motion. Hindi po ibig sabihin na kaguluhan ang dulot ng paggalaw na ito. Kaya po nadefine na violent dahil kailangan gamitan ng puwersa. Ang horizontal o violent motion ay kailangan ng tulak at HILA para mapanatili ang motion ng isang bagay. Kapag tinigilan ang pagtulak o paghila sa isang bagay ay humihinto rin ang pagGALAW.
#18 Ang projectile motion naman ayon kay Aristotle ay magkasamang natural at violent motion. A projectile motion happens when an object is moving parallel to the ground until it falls back to the ground. Ayon kay Aristotle, ang lahat ng mabibigat na bagay ay mas madaling bumagsak kaysa sa magagaan.
#19 The other concept came from the Italian Scientist Galileo. He is widely considered the father of modern physics.
#20 According to Galileo, if there is zero resistance, objects would fall back to the ground at the same time if released from the same height
#21 This is a recreation of the famous experiment by Galileo. Makikita natin dito na magkasabay na nahulog ang isang bowling ball at balahibo in a vacuum o sa isang silid na walang hangin.
#22 Ang pananaw naman ni Galileo sa horizontal motion ay hindi hihinto ang isang paggalaw kapag walang puwersa na makakapagpahinto nito.
#24 Galileo believed that a projectile is a combination of uniform motion in the horizontal direction and uniformly accelerated motion in the vertical direction. If it is not impeded, it will continue to move even without an applied force.  For example, when you shoot a ball in a basketball ring, the ball does not need a force to keep it moving.
#25 We discuss how Galileo was able to determine the acceleration of objects in a vacuum. Galileo dropped two different weight of cannons balls from a certain height in the Leaning tower of Pisa. It was in that experiment na napagtanto niya na kapag walang air resistance ay pareho lamang ang ACCELERATION ng anong bagay kahit gaano kabigat o kagaan ang mga ito.
#26 Ginamit naman ni Galileo ang inclined ramp at isang bola para masukat ang acceleration ng isang bagay. Kahit gaano kabigat o kalaki ang isang bagay ay pare-pareho ang oras ng acceleration ng isang bagay.
#27 It was in this experiment that he quantified speed which is (read the slide)
#28 Nadiskubre ni Galileo na dumudoble ang bilis ng isang bagay kada Segundo.
#29 Makikita natin sa table na ito kung paano dumodoble ang bilis ng rolling ball kada Segundo..
#30 So after the experiment performed by Galileo he was able to developed his first concepts of the laws of motion
#31 These are the concepts that galileo developed (read the slide)
#32 According to Galileo, objects in motion eventually stop because of a force called friction. Friction is a force that opposes motion between any surfaces that are touching. This is based on his experiment observed in inclined planes. Galileo hypothesized that if friction could be entirely eliminated, the ball would reach exactly the same height. Or if the ball rolls horizontally and there’s no friction that acts on it, the ball will never stop
#33 Isaac Newton was born the year Galileo died. He expanded Galileo’s work and was able to formulate his famous 3 laws of motion.
#34 Newton’s first law of motion is based on Galileo’s idea of Inertia. His first law of motion states that (read the slide)
#35 INERTIA is the ability of the object to resist motion. It is proportional to the MASS of the object. Mahirap itulak ang isang bagay para gumalaw ito. Mahirap din itong pigilan kapag nagsimula na itong gumalaw.
#36 Dahil nakadepende sa mass ang INERTIA, alin sa dalawa ang mahirap pigilan kapag tumatakbo pababa sa isang matarik na kalsada? TAMA PO.
#37 There are 3 types of INERTIA. First is the inertia of rest
#40 Bakit gumagalaw, humihinto at nanatiling gumagalaw o nakahinto ang isang bagay? Dahil ito sa puwersa o FORCE. Ang puwersa ay isang PUSH o pull o tulak at hila. Ito ay sinusukat in NEWTONS.
#41 One Newton is the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. Thus, the following unit equivalency can be stated as:
#42 Ang friction ang isang puwersa na komokontra sa bawat galaw natin. Kaya tayo nakakapaglakad ng hindi nadudulas dahil may friction. Kapag maulan at maputik, kadalasan ay nadudulas tayo dahil sa walang friction o walang kumokontra sa pag-apak natin sa lupa.
#45 friction causes the molecules on rubbing surfaces to move faster and have more energy. Subukan ninyong pagkikiskisin ang inyong mga palad? Di ho ba umiinit?
#46 According to the 1st 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. So let us define WHAT ARE BALANCE AND UNBALANCED FORCE. A BALANCE FORCE is when the net force is equals to zero.
#49 The force produced by the right team is greater than the left team by 10N tipping the rope to the right direction

#51 At yan po ang ating tutorial session para sa linggong ito. See you next week, same time. Happy Monday sa ating lahat!

#30 So after the experiment performed by Galileo he was able to developed his first concepts of the laws of motion
#31 These are the concepts that galileo developed (read the slide)
#32 According to Galileo, objects in motion eventually stop because of a force called friction. Friction is a force that opposes motion between any surfaces that are touching. This is based on his experiment observed in inclined planes. Galileo hypothesized that if friction could be entirely eliminated, the ball would reach exactly the same height. Or if the ball rolls horizontally and there’s no friction that acts on it, the ball will never stop
#33 Isaac Newton was born the year Galileo died. He expanded Galileo’s work and was able to formulate his famous 3 laws of motion.
#34 Newton’s first law of motion is based on Galileo’s idea of Inertia. His first law of motion states that (read the slide)
#35 INERTIA is the ability of the object to resist motion. It is proportional to the MASS of the object. Mahirap itulak ang isang bagay para gumalaw ito. Mahirap din itong pigilan kapag nagsimula na itong gumalaw.
#36 Dahil nakadepende sa mass ang INERTIA, alin sa dalawa ang mahirap pigilan kapag tumatakbo pababa sa isang matarik na kalsada? TAMA PO.
#37 There are 3 types of INERTIA. First is the inertia of rest
#40 Bakit gumagalaw, humihinto at nanatiling gumagalaw o nakahinto ang isang bagay? Dahil ito sa puwersa o FORCE. Ang puwersa ay isang PUSH o pull o tulak at hila. Ito ay sinusukat in NEWTONS.
#41 One Newton is the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. Thus, the following unit equivalency can be stated as:
#42 Ang friction ang isang puwersa na komokontra sa bawat galaw natin. Kaya tayo nakakapaglakad ng hindi nadudulas dahil may friction. Kapag maulan at maputik, kadalasan ay nadudulas tayo dahil sa walang friction o walang kumokontra sa pag-apak natin sa lupa.
#45 friction causes the molecules on rubbing surfaces to move faster and have more energy. Subukan ninyong pagkikiskisin ang inyong mga palad? Di ho ba umiinit?
#46 According to the 1st 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. So let us define WHAT ARE BALANCE AND UNBALANCED FORCE. A BALANCE FORCE is when the net force is equals to zero.
#49 The force produced by the right team is greater than the left team by 10N tipping the rope to the right direction
