Mathematical Interpretation of acceleration due to gravity (Hindi) Video Lecture | Physics for Class 9

press the bell icon and never miss a
video from flip Academy
now let's start with a mathematical
interpretation of acceleration due to
gravity
I've been túcume kapa haka other Kobe
body humming particular heights a ground
hitter of faking a the warm body co
Humphrey falling body considered
currently Otto's condition may was body
per coin he forced acne Karenga except
for the gravitational force escuela
Veronica de Hatake Jess is a simple body
ground Katara Fatiha they say where say
whose body keep velocity constantly
change ho t hair always changing
velocity he verges a was body may have
acceleration produced so type a QT O's
body make gravity upon a role play kadhi
hey dose schedule acceleration hey Oscar
nom Romney gravity Gaston Julia or
squabble dia acceleration due to gravity
Julia miss acceleration goes imagination
let's consider a very small example this
example may hum a coochie building kit
Chuck big head a hair of AHA say how
many ball Kenichi drop gear about coach
measurement Lena Shahrukh Earth Day and
Jess a time one second may let's say the
distance travelled by the ball is 4
meter and the velocity of the ball is 9
point 8 meter per second
totally ok pal firstly up record create
the time to second may do distance ball
new travel Kiowas nada hey legs say 18
meter and the velocity now turns to
nineteen point six meter per seconds a
ball or Nietzsche okay let's same time
three seconds a ball into distance
travel gear it is what is frame meters
and the velocity of the ball is now
recorded is twenty nine point four meter
per second ever stable shot the exact
technique Jessie Jessie free-falling
body key have nebulosity recoil key whoa
jab ground guitar authority the velocity
of key constantly increase Holyhead a
girl's condition male
find out curry Delta V Delta V money the
change in the velocity to arm the icky
icky first condition Miyagi velocity 9
point 8 meter per second second meaty
nineteen point six meter per second to a
girl happened oh no ko subtract clingy
to our classic emulator 9 point 8 meter
per second a gram second or third
velocity ko subtract currently that is
twenty nine point four minus nineteen
point six those condition may again you
will get Delta V is equals to 9 point 8
meter per second Mike Lamonica dekha key
velocity MIT increased the curly head
but at a constant rate Q key don't okay
beach go to gap headed this Delta V will
help point per constant here and it is
not changing with respect to the time
duska McLovin caucus at the hand that
change in velocity per unit time is
constant
Ohama already suffered a kayaking
acceleration go to formula what the hey
it is given by the change in velocity
per unit time our change in velocity
upon time constant here the acceleration
be free-falling body kaykai's miacca
constant hoga to whom Kaka suck the head
that acceleration due to gravity for
free-falling body remain constant
AAHA mater hey is he could mathematical
interpretation may just the acceleration
due to gravity go home small GC
represent content or schedule unit here
we will represent is by meter per second
squared now let's go to what Isaac
Newton told us
Newton's second law may you know niihama
a bataya that force is equals to mass
into acceleration
McLovin of a body is a particular
acceleration Kisaragi move car t he
tours condition nose body for you for
slogra here it is proportional to mass
of the body and it is also proportional
to the acceleration of the body so you
know formula hey F is equals to M into e
he harus body me applicable head your
body a particular acceleration Cassatt
agree move can be him obvious condition
made that
free falling body case may be again ham
take a tamale body max aeration and
Hammadi body may master to schemata love
my hapa newton's second law huh music
acceptance of a key skill our Newton
Nikola benaiah head that is universal
law of gravitation the universal law of
gravitation according job gravitational
formula head that is capital F it is
represented by capital G multiplied by
capital M into small M upon R square
this my capital j ahead that is a
gravitational constant capital n is the
mass of the earth small M is the mass of
the body and R is the distance between
Earth and the body again I don't know
forces km bath current - you don't know
for sale Somali condition we can equal
hey - humming don't know for Cisco equal
put car sucked and I can have the donor
equation co-equal cardia - of the hey
small M of small M don't know that of I
LHS or RHS McCann sahaja yoga or aapko
apne equation could modify and case
small jika formula banana the small G
caca formula any donor equation ce que
Haga capital g multiplied by capital M
upon R square so this is a very
important formula for acceleration due
to gravity its formula make capital G is
the gravitational constant capital M
again the mass of the Earth and R is the
distance between Earth and the objects
that is the efficient due to gravity is
inversely proportional the distance
between the earth and the body though no
car to distance here I use per
which gets Quayle per who inversely
proportional him up dickhead it's
condition may have care sack think you
got homology value but hang it though
homology key value come Jose I ghee take
an APNIC rakia up suppose homologa body

pearl consider Calvin a girl up key body
earth key surface for a key guy here
those condition may to center of the
earth a buscar or body to earth key
surface for a key Gaia Donna
bitch cut distance ah kitna jaga that is
the radius of the earth whose condition
may have small our ki jagah capital our
same equation we substitute cuttingly
and capital R represents the radius of
the earth to a huge acceleration due to
gravity hey special case may it's a
formula ki jagah capital G multiplied by
capital M upon capital R square now q
Nahum earth key bodka then to earth key

are one key value come his condition may
according to G is inversely proportional
to R square acceleration due to gravity
Aki increase ho jayegi similarly again
I'm equator giveth curry to equator pay

equation we put canapa activation due to
gravity aku come Milegi customer from
captain
dr. Campos for Karina to wahap our
acceleration due to gravity sada Hoagy
or agronomic we typically head to WA
high acceleration due to gravity come
now let's move on to the second part of
this particular topic that is to find
out the value of g that is acceleration
due to gravity again let's move on to
the formula that is g is equals to
capital G capital M upon capital R
square total condition make capital G
key value mind kidney Oogie 6 point 6 7
into 10 is power minus 11 Newton meter
square per kg squares or capital M that
is mass of the earth is given by 6 into
10 this part 24 kg while capital R which
is the radius of the earth is given by 6
point 4 into 10 raised to the power 6
meter all putting the values and
rearranging you we get the value for G
that is 9 point 8 meter per second
square to usual value head this says the
standard and the reference value for the
excavation due to gravity now let's move
on to the third part of this topic and
the topic is to modify the equations of
motion in the case of free falling
bodies hum nice belly kappa r that there
are 3 equations of motion that is V is
equals to u plus 80 s is equals to UT
plus half ay T Square and v square minus
u square goes to 2a s in normal
consideration metha when we considered
the object is moving with acceleration a
agar hum any teen equation go free
falling Modica case may consider Curie
those condition may acceleration a
Yokohama ha capital dengue G put
Carnegie that his acceleration due to
gravity put curving it Jo distance SJ
hamara
whoa horizontal direction mm consider
cousin but his condition may s ki jagah
hum H foot guarding it that is the
height
we're the free-falling body has fallen
down though s ki jagah up cash
substitute carrying H substitute cutting
a and s is the vertical distance
vertical distance means the distance
along the y axis now aghanim you don't
know point who consider Caray no big
human equation gets a modified hoagie
these equals to u plus 80 ki jagah hung
kaput curling a above equation a man yo
j ye v equals to u plus GT similarly s
is equal to UT plus half ay T Square
cachaca upon put coordinate H is equals
to UT plus half GT square v square minus
u square is equals to 2 ASG Java now we
can put v square minus u square is
equals to 2 G H to yak equations change
who being here or year big question do
bunny head these are the equations in
the case of free falling bodies
