How do you value the 'mass' of a object? Does our atmosphere on the earth surface count? If yes, do we count? Sun is made out of mostly hydrogen, and we calculate it in a whole, so does it meant even one gram of air in the air just in front of us have it's own gravity? Even if we can just 'tear it apart' easily?
Interesting question. All atoms have mass and are attracted by gravity to other masses: solids, liquids, gases, humans, air, all matter. Just because water turns to ice or evaporates into water vapour, its atoms are influenced by gravity just the same - they retain their mass. Our atmosphere is attracted to the earth by gravity, and that's what keeps it in place and creates atmospheric pressure. Check out this website: www.scienceissues.org.uk , you can learn about gravity and how it affects atmospheric structure.

Another slight mistake - The scales to measure your mass on another planet wouldn't nessecarily show another value - It depends what type of scale it is. If it's a spring balance then yes, it would change. But if it's a counterweight balance then it wouldn't change.
Sir could you pls tell that if there is a question related to this topic will the gravitational force value will it be given in the exam or should we memorise the different gravitational force values? and why did that 100 become 0.1 in the apple question? PLEASE REPLY ASAP
The values of different gravitational forces should be given. But to be sure, please ask your teacher about it 😉 And in the example with the apple, 0.1 is kilograms, as the mass was given in grams (100g) we had to convert it into kg.
question: when doing an isometric exercise on a special machine, where the machine doesn't move, but, it senses the "Force" exerted onto the handle/foot pedals, and then tells you the equivalent mass per your pushing force, how can this be calculated? I know you have the gravity acceleration of 9.8 as a constant (imagine your handle is linked via a pulley to a downward stack of metal, and this "stack of metal plate" is computerized and can change infinitely), but how would the machine decide what mass value to use as you push harder and harder the immutable handle?
i hope someone can answer my question, what’s the difference between force and weight since the formula are same? or is it just the same thing? thank you in advance
Weight is a force (from gravity) but there are other types of force, for example the electrostatic force between electrically charged particles, which incidentally is the origin of the force exerted by a stretched spring, where atoms are pulled slightly apart against the electrostatic forces of the bonds. Force = m x a but weight = m x g where g is the acceleration due to gravity.
the earth revolves around the sun it is the sun heats a surface of the earth this surface becomes positive therefore another negative surface returns it is put thanks to the two poles which are negative and which are attracted by the sun. And the mass is the number of elements that can be heated.
I have question concerning the free fall objects if you don’t mind In vacuum; or in anywhere else in which air resistance is negligible; the objects are subjected to weight force only; thus having equal acceleration... But let’s think of it in this way ... if weight force is actually the force that acts on a mass due to gravity.. then object A of 1kg mass is subjected to 9.8N weight force and Object B of 10kg mass to 98N.. then upon neglecting air resistance; an object subjected to a 9.8 N and another to 98N actually have equal acceleration because of what ?? Greater mass, greater inertia needs greater weight force to regulate the acceleration??
At 6:14 why bathroom scale is showing a reading of 143kg. I understand though measuring weight it shows us the unit of mass but the reading should be 1400 as multiplying 56(your mass) by 25(gravity of Jupiter) we should get 1400kg not 143kg. I can't understand why you guys multiplied 56kg with 2.5 though the gravity is 25. Can you guys please make it a bit clear for me
You are right, the weight on Jupiter would be 56kg x 25m/s^2 = 1400N (please, note the units), as we show at 6:05. But if you brought bathroom scales to Jupiter, which are calibrated in kg on Earth, where g=9.8m/s^2, they would show m = W / g, which is m = 1400N / 9.8m/s^2, which equals 142.8 or 143kg.
If this is true, what is preventing us from being pulled deeper into Earth’s surface via gravitational force? Displacement; via the hard/solid surfaces on Earth’s surface. My reason for stating the above is to ask this question. If our sun supposedly has a greater gravitational force than Earth; because of its comparison in mass to Earth. Then what is preventing the Earth and all of the other planets in our solar system from getting pulled farther into the suns gravitational force? The best I could come up with is rotation.🤷♂️ But if this is true, then the rate at which a planet rotates could potentially be a factor in how strong a planet’s gravitational force is. I personally don’t believe mass is the only factor in determining the strength of gravitational force a planet has. This is only my opinion.
1. Think of you on a trampoline. The rubber 'floor' bends down and exerts a force on you equal to your weight (the force on you from gravity). When you stand on the earth the same thing happens, microscopically - the ground is displaced and the elastic force opposes your weight. The earth is made of solids and liquids, where the atoms are 'touching' - the electron shells of all these atoms repel each other and prevent them from collapsing, giving us the earth as we know it. There are huge stars in the universe called neutron stars where the huge force from gravity is able to overcome this repulsion of electrons and the atoms collapse into a sea of neutrons (made of proton+ plus electron-). Luckily for us the earth's gravity is not strong enough for that! 2. Swing a tennis ball round your head attached to a string. In order to keep the ball in orbit you have to pull continuously on the string. Let go the string and the ball doesn't fly away but instead it carries on moving in the direction it had just before you let go. So the same with the planets - without the force of Gravity the planets would simply move in a straight line. It is the force of gravity that pulls them round in orbit. 3. So no, however, the rotation of a planet will mean that the gravitational force is needed to keep objects on the planet's surface and the planet itself 'in orbit'. So an orbiting space station (for example) is kept in orbit by the gravitational force between the craft and the planet. Everything in the craft experiences the same force and orbit together. This is often called microgravity but this is not true - the force of gravity is still very much in force! 4. So the force of gravity depends only on the masses of the two objects attracted to each other and it decreases with the square of the distance between them.

Greater mass, greater inertia needs greater weight force to regulate the acceleration??

You are right, the weight on Jupiter would be 56kg x 25m/s^2 = 1400N (please, note the units), as we show at 6:05. But if you brought bathroom scales to Jupiter, which are calibrated in kg on Earth, where g=9.8m/s^2, they would show m = W / g, which is m = 1400N / 9.8m/s^2, which equals 142.8 or 143kg.
