Absolutely, just a simple helium balloon discredits the entire theory of gravity. Helium or hydrogen weren't even discovered when Newton came up with his flawed theory of gravity 😲@@MathieusTheWalkingWitness
The experiment shown in the beginning of the video was conducted by Henry Cavendish to calculate the value of Gravitational constant, which is 6.67×10^-11 Nm²/kg². Also, if the effect of gravity on smaller bodies is able to be shown just by suspending two small balls on a horizontal bar, then why isn't the effect of gravity shown elsewhere like this?
It's difficult to show the effect of gravity on smaller objects else where because of opposing forces like gravitational pull from other objects, friction, air resistance and much more other counter acting forces. "That's why Cavendish suspended the balls on a horizontal bar to eliminate friction and put it in a wooden box to try and eliminate other forces as well. We haven't done this elsewhere because it's difficult to eliminate the other opposing forces perfectly.
@@ovidius2000 That's erroneous and stupid. I myself in my physics degree did the Cavendish experiment, as every physics student does. It has been redone thousands if not millions of times. You can't go to the moon without a Saturn V, and we made only about 20 of them and used them all. Now we are building new rockets to do it again. Ditch your stupid handle and go study Science!!
Cavendish recognised that heat is a factor to cause his torsion balance to move. Imo nobody can achieve thermal equilibrium within their torsion balance because one cannot determine that the centre of a large lead ball is at the same temperature as the centre of a small lead ball. The same can be said with all other pieces of the apparatus especially if they are made with different materials, e.g. wood for the beam. Observing the torsion balance swing around slightly and putting the causation of that movement down to gravitational attraction is a great idea but one has to prove it is because of gravitational attraction and not just attraction of masses due to differentials in heat or perhaps some other unknown explanation. All Cavendish proved was that he had a vivid imagination!!! That's unsurprising though given he had lots of money, never married or had children, ate the same meal every day for most of his life and didn't like his portrait sketched or painted.
Newtons The falling of the apple hinted at the force of attraction. And the thought of the attracter came after having seen the apple fallen on the ground. So the idea came to the mind that the earth has got the power of attraction. And when he saw the apple coming down, he realised the force of repulsion. And as a matter of fact any one of them is quite sufficient to bring it down. Then, what for two are required? IN “Hadayiq-un-Najum, it is said: If a bullet is fired on the equal level it will go in straight line, following its own nature. This hints at the force of repulsion.

Gravity=intermass action with planck scale space time warping. Unlike some kinds of electromagnetic radiation, Gravity doesn’t peek at you from behind other masses. Line of sight force only.
When you are falling there are no forces acting on you. Its not till something acts to push you away from your gravitationally determined path that you experience a force. The curve of space time is so severe near our planets surface that it requires 9.8m/s of force to push you away from the equilibrium state in that curved space. The curve of spacetime determines your path. Its really counter intuitive but we are like the fish who are trying to understand water. This leads to some stuff that is really weird when you first hear about it , like orbits being a strait line. They make a lot more sense after it sinks in for a while.

The lever using a horizontal scale is replaced by ripples from a very high energy top quark in the nucleus of each atom. Rest is identical. Laws to keep are that a convex interactive surface is positive ➕. A concave interactive surface is negative. Each time waves cut, there is an attractive force bringing the bodies together due to the negative surface interaction. Photons are positive in interaction causing displacement, dispersion and expansion.

That's true for everyone. It's impossible to push yourself up. You push down on the Earth, and the Earth reflects the same push force back onto you. Since the Earth is so massive, it doesn't go anywhere from your push. But you do, from the Earth pushing back on you.
Is gravity affected by magnetism? I recall some comment that a strong magnet changed the normal gravity of objects near or within the strong magnetic system.
No, gravity is not affected by magnetism. Magnetism and gravity can coexist in the same situation, and the forces would add up as vectors, but one does not affect the other.
The law of gravity is one of the fundamental principles that explains how objects interact in the universe. It was formulated by Sir Isaac Newton in the 17th century and describes the gravitational force that pulls objects toward each other. Key Concepts of the Law of Gravity 1. Definition: Newton's law of gravity states that every object with mass in the universe attracts every other object with mass. This force is called gravitational attraction. 2. Gravitational Force Formula: Newton represented the law of gravity with this formula: F = \frac{{G \cdot m_1 \cdot m_2}}{{r^2}} Where: is the gravitational force between two objects. is the gravitational constant (a fixed value of approximately ). and are the masses of the two objects. is the distance between the centers of the two objects. 3. How the Force Changes with Mass and Distance: The more massive the objects, the stronger the gravitational force between them. The farther apart the objects, the weaker the gravitational force. 4. Universal Application: The law applies everywhere, affecting all objects in the universe, whether they are stars, planets, or smaller objects. 5. Planetary Orbits and Gravity: Gravity keeps planets orbiting around the sun. The sun’s gravity pulls on the planets, while the planets’ motion keeps them from falling directly into the sun. This balance creates stable orbits. 6. Weight on Earth: Gravity is why we have weight. Your weight is the gravitational pull Earth exerts on your body. If you went to a planet with more mass than Earth, you’d weigh more because of stronger gravity; on a smaller planet, you’d weigh less. 7. Free Fall and Acceleration: Gravity causes objects to fall towards Earth. This fall accelerates at approximately on Earth, which means an object’s speed increases by about every second it falls. Limitations and Modern Gravity Theory While Newton’s law of gravity works well for many cases, it doesn’t explain everything. In the 20th century, Albert Einstein developed the theory of general relativity, which describes gravity as a warping of space and time rather than a force between objects. This theory explains gravity’s effects in extreme conditions, like near black holes or very massive stars. In Summary Newton’s law of gravity helps explain why: We are pulled towards Earth and have weight. Objects fall when dropped. Planets, moons, and stars stay in orbit. This law changed our understanding of the universe by showing that the same force governs the motion of everyday objects and the movement of celestial bodies across space.
gravity, acording to general relativity, is the distortion of space-time that is created by any mass. gravitational force is, well, the force that is exerted on any object near a gravitational field. this can be calculated with the formula given in the video. gravitational accelerations is, again, the acceleration an object adquires when in free fall inside a gravitational field.
Wonder if any tried the hanging ball test in a vacuum chamber to take out the "air pressure" factor that many people that deny gravity or the earth's rotation use as a red herring,
Good. What happens if we drill a 100 mm Dia hole from North pole to south pole right through the Earth passing through the center of Earth and drop a 25 mm Dia lead (Pb) ball through center of that hole. What will happen to that lead ball?
@@awatt That I know. Assuming core is not hot only consider the mass of earth of cold core and there is a hole from one pole to the south pole and drop a steel ball of smaller diameter from one pole to the other, where will that ball come to rest????
@@leopardtiger1022 The sun, moon and Jupiter's gravity would also have an effect like they effect the tides. Also the Earth being barycentric adds another layer of complexity to this
@@awatt we can keep discussing and thinking of all those variables, best is one should conduct that experiment to know what actually will happen to that lead ball. Will it oscillate from North to South or will it slowly after many oscillations of ever diminishing amplitude come to rest at the center of Earth?
The sun is attracting earth and the earth is attracting moon. I am a little bit confused here that why the sun is not attracting the moon which is much smaller than earth. Would you like to explain please. Thanks
The origin of momentum creation is founded on the application of energy. Momentum serves as the initial cause of pushing and pulling. The energy, emanating from the internal core of a planet, is what gives rise to momentum, commonly referred to as gravity, and not due to the planet’s size, mass, or space-time curvature. For example, when energy is applied, it generates the necessary momentum for the actions of pushing and pulling. Without the application of energy, momentum cannot be established. Consequently, force cannot be exerted for pushing and pulling, as it lacks a physical existence. This, in turn, clarifies why force is not gravity. ~Guadalupe Guerra
Gravitational field & energy contained in gravitational field exist in space around & b/w mass bearing objects. What is source of gravitational energy? Does gravitational field borrow its energy from space since there is nothing else there except Space. Is space an energy field?
In general, the simplest form of object positioning around another object in space is spheroidal positioning. Just like Electrons around nuclear in atom , But why do the planets in the solar system form a disc around the sun?
Bhaskaracharya described gravity in the context of a geocentric model, not a heliocentric one. He does not seem to have concluded that the Sun, Moon, etc. also have gravity, ascribing it as a property of the Earth. He did not create any mathematical description of how gravity works
Not only a theory, that's the thing how actually things work.... According to Newton's 2nd law of motion, F=Ma M=F/a Now, we know that Apple and Earth pulls each other with equal force. Earth Mass is much much greater than the mass of Apple. If the Mass is higher then the acceleration becomes lower, As Mass and acceleration are inversely proportional to each other. Earth Mass is much much higher than the Apple's Mass, So Earth's acceleration towards apple will become approx Zero. That's why Earth doesn't moves towards apple, only apple moves towards earth....
@@HarshaHarshG-tb3pu Ok, give me your take on how gravity causes acceleration between masses? Traditionally it’s the radius adjusting it, but…why and how does this measurement really do the deed? I have a hypothesis as to how it works, but would like to see if you have something different first.
You have to think in terms of Inertia. Basically Earth have more Inertia than Apple, As Inertia and Mass are Directly proportional to each other. Inertia is like Laziness, Earth doesn't want to move towards apple as Earth Mass is greater than the Apple's Mass. Only Apple moves towards the Earth.
Tudo muito bem explicado. Mas que tipo de força é a gravidade??? Elétrica, Magnética, nuclear, mecânica, alguem sabe dizer??????? Nem Isaac newton saberia.
Long time ago people find, that earth is not ideal sphere, and even centre of the mass is not fixed. In simple words directions of gravity will not intersect in the same point (centar of the earth), or vertical will not be vertical but declined for some part of the second.
Because gravity is a two way street. Earth causes a gravitational force on you, and you cause a gravitational force on it. If we can measure what gravity two known masses would cause on each other, and measure their own weights, as Cavendish had done, we can apply this knowledge to find the mass of the Earth.

Wonderful
Wonderful explanation
The law of gravity is one of the fundamental principles that explains how objects interact in the universe. It was formulated by Sir Isaac Newton in the 17th century and describes the gravitational force that pulls objects toward each other.
Key Concepts of the Law of Gravity
1. Definition: Newton's law of gravity states that every object with mass in the universe attracts every other object with mass. This force is called gravitational attraction.
2. Gravitational Force Formula: Newton represented the law of gravity with this formula:
F = \frac{{G \cdot m_1 \cdot m_2}}{{r^2}}
Where:
is the gravitational force between two objects.
is the gravitational constant (a fixed value of approximately ).
and are the masses of the two objects.
is the distance between the centers of the two objects.
3. How the Force Changes with Mass and Distance:
The more massive the objects, the stronger the gravitational force between them.
The farther apart the objects, the weaker the gravitational force.
4. Universal Application: The law applies everywhere, affecting all objects in the universe, whether they are stars, planets, or smaller objects.
5. Planetary Orbits and Gravity: Gravity keeps planets orbiting around the sun. The sun’s gravity pulls on the planets, while the planets’ motion keeps them from falling directly into the sun. This balance creates stable orbits.
6. Weight on Earth: Gravity is why we have weight. Your weight is the gravitational pull Earth exerts on your body. If you went to a planet with more mass than Earth, you’d weigh more because of stronger gravity; on a smaller planet, you’d weigh less.
7. Free Fall and Acceleration: Gravity causes objects to fall towards Earth. This fall accelerates at approximately on Earth, which means an object’s speed increases by about every second it falls.
Limitations and Modern Gravity Theory
While Newton’s law of gravity works well for many cases, it doesn’t explain everything. In the 20th century, Albert Einstein developed the theory of general relativity, which describes gravity as a warping of space and time rather than a force between objects. This theory explains gravity’s effects in extreme conditions, like near black holes or very massive stars.
In Summary
Newton’s law of gravity helps explain why:
We are pulled towards Earth and have weight.
Objects fall when dropped.
Planets, moons, and stars stay in orbit.
This law changed our understanding of the universe by showing that the same force governs the motion of everyday objects and the movement of celestial bodies across space.
Pls guide me, what is actually the difference between the gravity, gravitational force, and the gravitational acceleration??
gravity, acording to general relativity, is the distortion of space-time that is created by any mass.
gravitational force is, well, the force that is exerted on any object near a gravitational field. this can be calculated with the formula given in the video.
gravitational accelerations is, again, the acceleration an object adquires when in free fall inside a gravitational field.

The origin of momentum creation is founded on the application of energy. Momentum serves as the initial cause of pushing and pulling. The energy, emanating from the internal core of a planet, is what gives rise to momentum, commonly referred to as gravity, and not due to the planet’s size, mass, or space-time curvature. For example, when energy is applied, it generates the necessary momentum for the actions of pushing and pulling. Without the application of energy, momentum cannot be established. Consequently, force cannot be exerted for pushing and pulling, as it lacks a physical existence. This, in turn, clarifies why force is not gravity. ~Guadalupe Guerra

So in the center of the earth, gravitational force is equal in every direction, thus there is no gravitational force there. Am I right?
Yes
well-explained i understood even though i m in year 8
How long to wait for the experience described in the beginning
Great Mathematician Bhaskaracharya discovered Gravity and Laws of Motion centuries before Sir Isaac Newton
Bhaskaracharya described gravity in the context of a geocentric model, not a heliocentric one. He does not seem to have concluded that the Sun, Moon, etc. also have gravity, ascribing it as a property of the Earth. He did not create any mathematical description of how gravity works
Thank you ❤❤
I'm inspired by this content. A similar book I read served as a transformational guide. "Galaxies United" by Olivia Whitestone
Nice narration..!! Apple pulls the earth.. quite a theory
Not only a theory, that's the thing how actually things work....
According to Newton's 2nd law of motion, F=Ma
M=F/a
Now, we know that Apple and Earth pulls each other with equal force.
Earth Mass is much much greater than the mass of Apple.
If the Mass is higher then the acceleration becomes lower, As Mass and acceleration are inversely proportional to each other.
Earth Mass is much much higher than the Apple's Mass, So Earth's acceleration towards apple will become approx Zero. That's why Earth doesn't moves towards apple, only apple moves towards earth....
@@HarshaHarshG-tb3pu Ok, give me your take on how gravity causes acceleration between masses? Traditionally it’s the radius adjusting it, but…why and how does this measurement really do the deed? I have a hypothesis as to how it works, but would like to see if you have something different first.
@@starventure Aree kahana kya Chahte ho....!!
@@starventure I didn't get what you said.
Can you elaborate your Comment plz.
You have to think in terms of Inertia. Basically Earth have more Inertia than Apple, As Inertia and Mass are Directly proportional to each other. Inertia is like Laziness, Earth doesn't want to move towards apple as Earth Mass is greater than the Apple's Mass.
Only Apple moves towards the Earth.
But how that time peoples knows about the distance of moon ?
you are a great explainer dude
Wow..i knew here better❤
Thank you so much🤩
Tudo muito bem explicado. Mas que tipo de força é a gravidade??? Elétrica, Magnética, nuclear, mecânica, alguem sabe dizer??????? Nem Isaac newton saberia.
Long time ago people find, that earth is not ideal sphere, and even centre of the mass is not fixed. In simple words directions of gravity will not intersect in the same point (centar of the earth), or vertical will not be vertical but declined for some part of the second.
By the way nice video 😊
How u can know exacly mass of earth without measure weight of earth?
Because gravity is a two way street. Earth causes a gravitational force on you, and you cause a gravitational force on it. If we can measure what gravity two known masses would cause on each other, and measure their own weights, as Cavendish had done, we can apply this knowledge to find the mass of the Earth.
How did henry calculated it, pls i really want to know
Can you plz explain the friction force
Does the ball thing work in a vacuum?
especially in the vacuum.
because the balls dont need to push through the air.
It would work even better there, as there would be no air resistance.
I also convince that Isaac Newton is incredible .
Sir mera question hai ki
Agar ham dono pindo ki bich ki duri ko aadhi kar de to bal yani F kitna Guna ghat jayega ya kitna Guna bhad jayega
f=g*m1*m2/(d/2)^2
