together

pretending to know whispers

lalala Syalala

Sya

Lala Have you ever seen an airplane

observe How can an airplane take off

why don't metal ships

sink Yes

curiosity observation is

part of the nature of physics, you know

before knowing the nature of physics Let's

first know a little about

What is science and what is physics

What is science

knowledge network of

observation and research

only we are

hurt by this whisper of biology

science is a science that

humans study from

observation and research activities to

find out the agreed theory

more about What is science

you can watch this musicalization video

[Music]

What is physics

[Music]

[Applause]

[Music]

physics is a branch of

natural science that studies

natural phenomena and the relationship between

natural phenomena themselves

for more details you can

watch this musicalization video

[Music]

guys before we continue for those of you

who haven't subscribed to this channel,

please subscribe first so you don't

miss other interesting learning videos

Now let's continue with

the material with me Angel for the

next few minutes

because physics is part of science,

the nature of physics is the same as the

nature of science the nature of physics consists

of three parts the first is

physics as a product second physics

as a process third physics

as an attitude

approximately three things mentioned

earlier what are they

let's watch the video again of course

with more focus yes

1 Physics as a product the

product produced in the form of a collection of

knowledge that is systematically arranged

which is the result of discoveries

from various investigations consisting

of facts or realities concepts principles

laws

formulas theories and models

facts or realities are the

actual state of an object or

natural phenomenon that occurs

for example airplanes can fly

even though they are heavy and made of

metal and ships that are

very large and made of metal

do not sink

concepts concepts are abstractions of

various events objects phenomena and

facts elements of the concept are

names definitions attributes values ​​and examples of the

concept of dynamic fluids

related to airplanes

and static fluids related

to ships

principles are

generalizations of the relationship between facts

and concepts

for example Bernoulli's principle an increase

in the speed of fluid flow will

cause a decrease in pressure on the

flow

and Archimedes' principle every object that is

inserted into a fluid either partially

or completely will get an upward force

that is equal to the weight of the fluid

displaced

laws are

special principles that are

widely accepted after

repeated testing and their truth

has been recognized supported by

scientific evidence

for example Bernoulli's law which states

that the sum of the pressure of kinetic energy

per unit volume and potential energy per

unit volume has the

same value at every point along a

straight line

and Archimedes' law which states

When an object is immersed in

a liquid, the object

gets an upward pressure that is equal

to the weight of the liquid that is

pushed by it

[Music]

formulas are mathematical statements

of a fact, concept, principle, law,

and theory. The

first formula is Bernoulli's law formula,

namely P plus half ro

v² + rogh = constant or P1 plus

half row v² 1 plus rogh1 = P2 +

1/2 love² 2 plus rog H2 with

the information that Pro is the density of the

fluid G is the acceleration due to

gravity V1 is the pressure at a

height of 1 V1 is the speed at a height of

1 H1 is the height of height

1 P2 is the pressure at a height of 2 V2 is the

speed at a height of 2 and

H2 is the height at a height of 2 the

second formula is Archimedes' law formula

Fa = ro liquid multiplied by VB multiplied by

G with the information that Fa is the buoyancy force in

units Newton FB is the volume of an object

inserted into a liquid,

its unit is cubic meters, G is

the acceleration due to gravity, its unit is meters per

second squared, Pro liquid is the

density of a liquid, its unit is kg per M3,

theory, theory is an explanation

based on various observations

supported by experimental results,

examples of theories are the theory of fluid

dynamics and the theory of static fluids,

models are representations of

something that is often too difficult or

impossible to display directly,

for example, airplane wing models

and ship models,

2 physics as a process of

understanding physics as a process

related to phenomena, assumptions,

observations, measurements, investigations and

publications, the processes used include

observing or observing,

classifying,

measuring, asking questions,

formulating hypotheses, formulating problems,

interpreting or interpreting

information and communicating. The

following is an explanation of

physics as a process

[Music]

1 observing or observing observing

or observing is done

by 1 explaining what is

observed through

quantitative or qualitative observations, 2 noting

similarities, differences, regularities and

comparing, 3 making observations in a

certain period and noting things

that are not appropriate, 4 explaining a

pattern, the

second classifying,

classifying is done by 1

giving a sequence to events that

occur, 2 looking for similarities and

differences, 3 determining criteria and

placing groups based on

criteria by selecting and

separating with certain groups

based on their characteristics found

in the observation

third

measuring measuring is done by 1 choosing a

measuring tool that is appropriate to the research

or experiment being conducted 2

using a measuring tool with a

certain accuracy and ensuring that the measuring tool is

functioning properly 3 finding

measurement uncertainty by

using the rule of significant figures

fourth asking questions

[Music]

asking questions is done by

one asking as many

questions as possible in accordance with the research 2

identifying questions that can be

answered with scientific findings 3

formulating questions based on a hypothesis

fifth formulating a hypothesis a

hypothesis is a temporary answer to

the problem being studied so that

its truth must be tested empirically

formulating a hypothesis is done by

1 explaining observations in

terms of concepts and principles 2

using explanations to make

predictions from problems that can be observed

or proven 3 planning

research or experiments

sixth formulating problems

formulating problems is done by

1 designing a way to make observations

to solve problems 2 choosing tools

and materials that are appropriate to the research

or experiment to be conducted 3

determining the steps of the experiment

carefully, correctly and maximally fourth

determining a fast way to

collect data in accordance with the technical

or process that has been planned

previously

7

interpreting or interpreting

information

interpreting or interpreting

information is done by 1

concluding the results of research or

experiments that are tentative 2

make and seek justification for

temporary conclusions 3 make predictions

based on certain patterns and from the results of

this research gives rise to research The

next related research

and the 8th communicating

communication should be done by

1 Explaining activities verbally

using diagrams 2 using

graph tables or models to present

information 3 choosing the most

appropriate way to present information

using the right method 4

using the right information technology

or using indirect sources

to obtain information

3 physics as an attitude

[Music]

scientists must have a

scientific attitude guys, what are the

scientific attitudes, do you know? Well, here

are the scientific attitudes that

a scientist must have, the

first is curiosity

and likes to ask questions,

the second is thorough, the

third is objective and honest,

the fourth is responsible,

the fifth is critical and creative, the sixth is

open-minded,

and the seventh is diligent and not easily

discouraged, friends, that was

my explanation about the material

nature of physics, hopefully after

watching this video it can increase

our insight about How

important physics is in our lives

natural science that studies

natural phenomena and the relationship between

natural phenomena themselves

and the processes used, namely
