We saw that the gravitational force is the attractive force between any two objects with non-zero mass seperated by a distance. So does the Apple fall towards the Earth or does the Earth move towards the Apple? Or do both move towards each other? It’s actually simple logic! This is the Earth, and say this minuscule object is an Apple. Based on what we learnt about the gravitational force, both apply an equal force to attract the other object towards itself. So if the forces are equal which one will accelerate more? Based on the Newton’s second law, we know that the force applied is the product of mass and acceleration. So the acceleration will equal ‘Force over the mass’. The acceleration is inversely proportional to the mass. If the mass is more, the acceleration will be lesser. As the mass of the Earth is MUCH MUCH MUCH more than the mass of the Apple, It is the Apple that accelerates towards the Earth and not the other way around. Hope that makes it clear. Now the question is ‘how do we quantify this force?’ To understand this, we need to understand a simple concept! And this simple concept is called the Universal law of Gravitation. Say there are two objects A and B separated by a distance ‘d’. The distance between the centres is considered the distance between the 2 objects and not this distance. Assume that the mass of object A is ‘m1’ and that of object B is ‘m2’. As object A is bigger, let’s assume ‘m1’ to be bigger than ‘m2’. The Universal law of gravitation says that, ‘Every object in the universe attracts every object with a force which is DIRECTLY proportional to the product of their masses and INVERSELY proportional to the SQUARE of the distance between them’. Let me repeat. The force is Directly proportional to the PRODUCT of their masses and INVERSELY proportional to the SQUARE of the distance between them. With this data, we can write it mathematically like this. So if the mass of any of the objects increases, the gravitational force will have more magnitude. And more the distance between the two objects, the lesser will the gravitational force! Directly proportional to the product of the masses, and inversely proportional to the square of the distance between them. This can be written as F equals G times m1 one times m2 over ‘d’ squared. ‘G’ here is the Constant of proportionality and is called the UNIVERSAL GRAVITAITONAL CONSTANT. The equation can be modified and written as G equals ‘F times d squared’ over ‘m1 times m2’. The value of ‘G’ was found out by Lord Henry Cavendish using a Torsion Balance. The universally accepted value of G is ‘six point six seven three’ times ‘ten raised to negative 11’. What will be the units of G? Force is Newtons. As the distance is in meters, we have ‘meters squared’. And as the mass is measured using kilograms, we multiply this with ‘kilograms raised to negative 2’. This is the value of the Universal gravitational constant!

In future don't memorise would be the most trending educational site ……bst wishes

btw gr8 explanation

helped me a lot ……ty don't memorise ::))

isn't Newton's "law" a theory, when did his theory of gravity, like Einstein's theory of gravity and relativity, become fact-law?

mam…ur videos is awesome….so clear and best channel for mee yet now…but there is problem there is no topics according to cbse….like i see ur all videos but no found the gravitation constant topic…no sequence wise

i really love your videos really 🙂 i m so happy wid ur videos

WELL DONE AND VERY GOOD FOR YOU thanks

Thanks

When will you make videos on space curve?

Spr… which software you using sir

Nice 1

OMG I am become your fan very very nice keep it up

What is the question? I didn't understand

Hindi m bnao naa

I am week in physics.so,please put more examples😣😣😣😐😑😥😥😣🤐

Hey. What if i were live in Mars could i use the same G constant .??? You say it universal

This video helped me a lot to understand the concept easily. thank you

thank u so much

Interesting

O my GOD! It's just fantabulous 👏…. I have understood this topic very easily…. thank you very much for this vedio

….. keep making these vedios …..

.

good explanation, nice work very brief

No object is put on

motion without the hit of an external force. Since there should be an

initially force applied to an object in order for the object to start

it state of motion, therefore there is acceleration involved for any

object in motion. As long as the acceleration is not zero the object

velocity should increase and increase to infinity, assuming the

object is not under the influence of any external forces at all.

Example, suppose an

object is suspended without any, whatsoever, forces acting on it.

Now, you hit the object with something. So the object will start its

motion. This means the object will begin with acceleration. Does

this positive acceleration remains with the object. Again assuming

the object not being subjected to any external forces. If the object

is under the influence of acceleration due to the initial hitting

then the velocity of the object will keep increasing and increasing.

So an object in motion will not continue its journey with constant

velocity. That is an object in heaven in motion must be under a

positive acceleration and with a non zero acceleration the velocity

keep increasing. Would you please clear me about this subject? Thank

you

Hello Could you inform me how you obtained the Universal gravitational constant – thanks

you speak too fast

good presentaion

G is directly proportional To square of distance I think urs explanation is very very nice

Thank I remember my college education

Best explanation .

Marvelous video thank you so much keep going on 👍👍👍

What a MAm I loved it

t

This is the best explanation video I have seen so far, really thank you for the simple clarifications. It made me understand the concept very quickly and easily, I hope you will continue doing this way. Keep it up and I’m sure you will be successful in the future (hopefully). 😄❤️👍

Mass as such does nothing. Neither attract nor repulses. Think about it. Why should this be so? It’s nonsense.

Please make the video for Kepler 123 law of motion

Thank u for making it clear👍💖😊

This "universal law" tells us, that gravitational force between Sun and Moon is greater than force between Earth and Moon, but Moon is still Earth's satellite…

Here's a dot will the both objects apply equal force or they will be promotional to massed

Excellent 👌😀

Y we want to take the distance from cente

Can anyone help me

What is electromagnetic force

Thank u so much

Very very great videos, very easy to understand, short and sweet, thanks a lot for animation video creation.

Keep it up. God bless you.

ho!!!!!!!!!!!!!!!

Mam i have only one question, that is why we take square of the distance??

I am not understanding, please help me mam.

Mam are you Indian.

Thank you! Very clear and succinct! That's how you make a science video!

Where can we see this phenomenon of mass attracting mass here on Earth perhaps near a big mountain?

To quote the Cavendish experiment is an embarrassment, have you researched it?

It was set in a room in or adjoining his house – the device was not his design it was passed to him and he carried out a few

modifications. It was primarily made of wood which as you know over time will suffer shrinkage and warping (He confirmed that moisture had ingress-ed some components).

Whilst continuing to take his readings he did the following; He subjected the balls to a flame to see what effect heat would have He subjected

the balls to magnets to see what effect magnetism would have.

He drilled holes in the balls to insert a thermometer He asked his butler / friend to carry on with the measurements when he went off for a few days.

There was no temperature control in the room (This is most critical)

His calculations have been found to be incorrect (Proven by Hutton).

After each one of these he should have re calibrated and started from scratch – he did not.

He also admitted the balls were not hung centrally on their axis but thought the impact was negligible.

Any one of the above would render any science experiment void yet we are supposed to believe a constant was achieved. Boys did a similar experiment far more scientific by a long shot than Cavendish but obtained contradictory results.

Hutton and Maskelyne determined their pendulum mountain experiments were far more accurate than cavendish.

Airy tried to find the mean density of the earth up and down a mine shaft but met with contradictory results also.

Transactions of the Royal Society 1847, Sir JFW Herschel On the Cause of the Discrepancies observed by Mr Baily with the Cavendish apparatus for determining the Mean density of the Earth he states; I must not here be understood as insinuating any kind of deception on the part of the great experimental philosopher, on the contrary he is candid in the extreme. He frequently refers to the 'variation in the time of vibration and perturbation of the resting points' as things for which he cannot account, and sometimes says 'there must be some disturbing

force'. also the force of torsion must be subject to variation'.

Herschel is also critical of the magnetising of the balls stating that despite being mainly lead they will retain some magnetic properties for a period of time.

The mean density of the Earth has never and will never be known therefore all calculations based on it are null and void. Look at these experts in their field try to embarrassingly explain gravity. https://www.youtube.com/watch?v=7lui9qZ6cDs&t=851s

All of the above are extracts from Cavendish himself and from Royal Society papers.

Why the gravitaional force attracts between two object

Why it is 1/d^2?? And why it cannot be d^3 or d^4 etc.. Explain this if you can.

But gravity escapes for a freely falling body

plz explain deeply

Thank you so much for such a amazing and understanding vedio

चेतावनी – गुरुत्वाकर्षण का अस्तित्व है ही नहीं । ये एक "अवैज्ञानिक कल्पना" है, जिसके कारण ही विज्ञान गलत दिशा में जा रहा है और आज भी ब्रह्माण्ड हमारे लिए एक, अनुत्तरित प्रश्न बना हुआ है I

यदि आप मानते हैं कि, वास्तव में गुरुत्वाकर्षण का अस्तित्व है तो, गुरुत्वाकर्षण बल की दिशा को, तीर के माध्यम से दर्शाने का प्रयास करे । जिस प्रकार, ब्रह्मांड में लगने वाले प्रत्येक बल की दिशा को, सरलता से, तीर द्वारा प्रदर्शित करना संभव है । मेरी आपको चुनौती है, आप नहीं दर्शा पाएंगे, क्योंकि वास्तव में गुरुत्वाकर्षण का कोई अस्तित्व है ही नहीं ।

लेकिन, वो कौन सा बल है, जो गुरुत्वाकर्षण के स्थान पर, वास्तव में कार्य कर रहा है? इसकि ठोस जानकारी के लिए, क्लिक करें – https://youtu.be/q_Zqr0cUcI8

Bestest for learning 😍

Erm….gravity isn't a force. Can't you science?

👍👍👍

Wonderful explanation 👏👏

Why distance square

Mam I am watching your videos since last two years and these prove very helpful for me but mam I request you to clear my doubt regarding how planets revolve around sun? Man please clear my this doubt. I will be thankful to you If you clear my doubt

why moon not fall to the earth though?

Thanks

What is constant

Thanq for explainig

What a great and simple explanation!! Thanks alot for this simplification.❤❤❤

mam I am from Tamil Nadu you are so…. awesome

This woman should be my physics teacher 😍😍😍 thank youuu

Thank you so much😍

Who else just wants to kill that apple sh*t 🍎 ? Only me? ok then…… because it all started with that apple who just couldn't stay on that tree…..😡

Will you be my physics teacher 🌹 pls??

Thanks for telling this information

Why there is d square

Osm video 👌 👌

Mam, why do we take square of distance between two masses, why not only distance?

Nice

Good explanation 💓💓

I never thought that Physics could be explained in such a simple manner yet effectively. Thank You, Don't Memorise 🙂

Why is this in grade 6

Newton ki maaki ki

***Thank you

Hii , I know it's a wierd doubt but I want to know your nationality.

U rock our study

Amazing

Best explanation for me.😊😊😊😊😊Thank you soooo much. ☺☺

Tqq so much

G ki value universal ne 6.673×10 hi rakha

Why planets don't attract to each other??

For me, Newton's gravity laws are NOT correct, even according to Newton …

In fact if we have A(M) and B(m) and M > m, so F(A/B) = G'(M + m)m/AB² and F(B/A) = 0 (G' is a little bit smaller than G = 6.67 x 10⁻¹¹ isu)

My question is : what happens if we have M = m ? (the answer is very logic …)

It is nice

GOOD WONDERFUL

EXPLANATIONS

THANKS&&&&&&&&&&&&&&&&&&&&&&&&&&&&

I like jacket but I want in india

Good quality. Visual s 😎

Mass increase -> magnitude of gravitational force increases

Greater the Distance between two objects, lesser the gravitation
