FAQs on Free fall and Acceleration due to Gravity (Hindi) Video Lecture - Science Class 9
| 1. गिरावट और गुरुत्वाकर्षण के कारण मुक्त गिरावट और गति क्या होती है? |  |
उत्तर: मुक्त गिरावट एक ऐसी स्थिति है जब एक वस्तु को कोई बाह्य बल नहीं रोकता है और वस्तु केवल गुरुत्वाकर्षण के कारण गिरती है। गुरुत्वाकर्षण एक बाह्य बल है जो हमें धरती के केंद्र की ओर खींचता है। गिरावट के समय, वस्तु गुरुत्वाकर्षण के बल के कारण नीचे की ओर गिरती है। गति वस्तु की चाल को कहते हैं। गिरावट के समय, वस्तु की गति कारण गुरुत्वाकर्षण के बल के समान होती है।
| 2. मुक्त गिरावट के दौरान गिरते समय वस्तु की गति का क्या होता है? | |
उत्तर: मुक्त गिरावट के दौरान वस्तु की गति समय के साथ बढ़ती है। इसका कारण है कि गिरावट के दौरान केवल गुरुत्वाकर्षण बल ही वस्तु को नीचे खींचता है, बाह्य बलों नहीं। इसलिए, जब वस्तु गिरावट के दौरान नीचे की ओर गिरती है, तो उसकी गति समय के साथ बढ़ती है।
| 3. गुरुत्वाकर्षक क्षेत्र क्या होता है? | |
उत्तर: गुरुत्वाकर्षक क्षेत्र एक ऐसा क्षेत्र है जो एक विशेष वस्तु के चारों ओर मौजूद होता है और जिसके कारण उस वस्तु के चारों ओर दूसरी वस्तुओं को आकर्षित किया जाता है। गुरुत्वाकर्षक क्षेत्र धरती के केंद्र की ओर से बाहर बढ़ता है और गुरुत्वाकर्षण बल के वजह से हमें धरती परीक्षण महसूस होता है।
| 4. गुरुत्वाकर्षण बल कैसे काम करता है? | |
उत्तर: गुरुत्वाकर्षण बल द्वारा वस्तुओं को आकर्षित किया जाता है। गुरुत्वाकर्षण बल वस्तु और धरती के बीच आकर्षण का कारण है। यह बल सीधे धरती के केंद्र की ओर खींचता है। बड़ी वस्तुओं को धरती के साथ आकर्षित करने के लिए इस बल को महत्वपूर्ण माना जाता है।
| 5. गुरुत्वाकर्षण के बल की गति क्या होती है? | |
उत्तर: गुरुत्वाकर्षण के बल की गति नहीं होती है क्योंकि यह एक स्थिर बल है। गुरुत्वाकर्षण बल वस्तु के ऊपर केवल एक बार कार्रवाई करता है और वस्तु को एक स्थान से दूसरे स्थान पर ले जाता है। इसलिए, गुरुत्वाकर्षण के बल की गति नहीं होती है।

now let's start with the topic that is
free fall of the free fall sick cam
MATLAB hamana Java GUI body a particular
height say agar Giggy a skittle of those
condition may were - body hair was go
home free fall body considered curtain
iris condition may as we all know that
any object if it fall towards the earth
then there exists a gravitational force
of attraction and that is due to the
earth the job be Humphrey falling body
keep asking me to waha / hamster for
chef aid for ski becoming gay that is
the force of gravity to cajas Allegra hi
Joe earth cabbages Allegra head was
free-falling body k Cooper is a lava ome
external force was free-falling body per
applicable nahi hoga so now again let's
define that what is a free-falling body
a free-falling body is a body when it
falls from a particular height only
under the action of the gravitational
force of attraction provided by the
earth now the question that striped many
philosophers mind they were continuously
thinking and investigating on one
particular question that is if there is
any change in velocity of the
free-falling body the fourth important
question rehouse chamber to face her a
3d game or end may humming capita chala
give velocity could change chronically
it basically having no parameters his
service party hey it to velocity
dependent i direction pal
or those free depend card i have
magnitude but my body
Hooper say humph a crane have free fall
hey Tues condition may was cut direction
to constant a lickin jab in the body you
person ichika t hey those caves velocity
continuously change ho teria t hey Jesse
Jesse body ground ki tarah facility here
they say we say escape velocity
crease daddy hey it's cool clearly so
much Nikoli let's perform a very simple
experiment now let us consider a ball
which is drawn from a height tall
building average condition may ball jab
Nietzsche Adi here some ham Nick was
recording ski subsequently how many time
record key of one second
just my balm a distance travel here four
meter and the velocity of the ball
recorded is 9 point 8 meter per second
similarly how many do free second may
time record here um distance ah de ball
new travel cardia that is let's say 18
meter or this condition major velocity
how many record key that is nineteen
point six meter per second
Jessica's even et re here to homina fits
the time but la that is three second or
they still do record Kiev Oh optimism is
aa DeJoria that is 43 meters of velocity
above me record key that is twenty nine
point four meter per second third case
may APNIC addict hockey jessica's the
ball earth ki taraf Adi hey escape
velocity continuously increase holy here
yeah from care sack time velocity
continuously change holy head or Yemeni
already Pyar Kiya kita hopper change in
velocity ho t have a hepatic terminate

Aristotle in a homesick Calcutta and
it's totally hamsa Ekka hatak is a

jelly ground per guilty hey as compared
to lighter objects and who perform some
experiments also who donate metal cocoon
Leah or Deus rehab my feather Leah the
metal coin is heavier and feather is
lighter
I don't know we extract known a ground
heater of gaia and he found that metal
coins strike the ground at a faster rate
as compared to the feather feather news
Addis Emilia groundhog fortunately
though some may have me mystically a
concept did you hear that
yes heavier objects strike the ground at
much less time as compared to lighter
objects he concept hum tuk tuk monte the

keep acceleration due to gravity is
independent of the masses or experiment
get through you know near score proof
Kia Doha conclusion rocker sucked a hair
that acceleration produced by the
gravity is independent of the masses of
the object to a conclusion it's very
important and this is the main
fundamental concept of acceleration due
to gravity now let's summarize what we
have studied till now the first is that
the free-falling body is the body that
falls from a particular height towards
the earth under the action of
gravitational force only the second is
that as the object falls towards the
ground
then it's velocity continuously
increases the third alien acceleration
