Understanding Universal law of Gravitation!

Let's understand what is universal law of gravitation and how Sir Isaac Newton discovered it in detail.

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.

[@royalemperor9007]

Lol Newton proposed "what goes up must come down" and "mass attracts mass" around 1666... Helium (has mass and NEVER goes down) was discovered in 1868... There is no universal law of gravity attraction, cause a simple gas such as helium, debunks that allegedly claimes "law"... i highly suggest you go watch Richard Feynman lecture about how laws of nature are discovered...

[@M1551NGN0]

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?

[@noredem]

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!!

[@PeterPete]

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.

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.

This is what I learnt in school in the 1950s.....but my head is spinning from theories that Gravity is NOT a force.

[@starventure]

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.

[@leopardtiger1022]

Space Time trampolin is NOT correct reason for gravitational motion we observe.

[@BadOompaloompa79]

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.

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?

[@saveearth9816]

Very good explanation I have a question :- we know that if we have 3 unknown values in an equation we need 3 equations to solve the problem & find the solution..... I will clearify the question the 3 unknown values in Newton's gravitational law (f=G×m1. m2 /r2) are the G gravitational constant.... m2 mass of the earth.... And r the earth radius So if we put 3 different weights (m1) three times & by computation of the gravitational force (f) each time and because we know (m1) so we can figure out the other 3 values (G.... m2.... r) Is my English good?

[@carultch]

Your English is good enough for me to understand approximately what you have in mind, but your question is incomplete. Think carefully about what information you know, and what information you want to find. Without knowing specifically what information is given, I can't help you.

[@IhabFahmy]

No, because every time you change m1, then F also changes... and you thus end up with a new value for the equation.

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.

[@rajchoudhary4349]

Nice narration..!! Apple pulls the earth.. quite a theory

[@HarshaHarshG-tb3pu]

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....

[@starventure]

@@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.

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.

[@KirbyProffitt-ic8gl]

The torsion wire experiment can never be exactly perfect unless each known mass has the exact same number of atoms. This is why we haven’t been able to get an exact measurement. The previous experiments have used 4 masses of known weights yes, but a slight variation in density in each mass would give several different outcomes due to the amount of atoms and densities. The best way would be to measure each mass’s attraction to each mass in the system. Aka each mass is rotated into all possible points and measured. 16 different measurements. But this also has issues to be able to repeat the precise position as each mass is moved to a new position. Also the tension wire will never have the same torque value repeatedly. I’m working on a new experiment model that should eliminate this inconsistency and also prove another theory(s).
