Since the last two days, i am using your channel and whenever i get a headache after seeing my physics book, i see the same topic on your channel..... Subscribed and liked..... Thank you 😇
Weight - magnitude of gravitational force on an object Mass - amount of matter inside of an object Density - the concentration of matter in a particular volume inside of object
in school I used to hate topics like physics and math, thanks to youtubers like yourself I'm rediscovering the joy of learning mathematics and physics. Schools need to be reformed ASAP.
Mass = Quantity of atoms/matter within an object. Weight = Quantity of atoms/matter within mass/object resisting gravity and inertia. Gravity and Inertia = Ether/Aether flowing from space towards earths internal electric charge giving all objects on earth its weight.
You explaination is great, I understand those things very easily with it.Even in my online my teachers use your few videos to clear our concept more better.😃😃
I learned lot of things ....your teaching skills are 100x compared to my personal tutor she explains exactly like you but i can't my question is why i can't understand lol 😂😂 2 days = full revision k.o. Edit : Ooo gosh i got 98 percentile 🤩🤩
Mam as you said that mass is the amount of matter present in an object, right? My question is how can we measure the AMOUNT OF MATTER present in an object??? (Apart from the formula m=w/g)
Yeah thats a good question, bc all they say in this vid is that those 2 things are not the same, but then they actually axplain than they ARE the same while on earth!
@ali tornado i think you just weigh yourself here on earth, don't see how else. Maybe with some high tech science stuff you can measure the amount of matter, but I don't think it really *matters* anyway
Good question. You can determine your mass without depending on gravity, by using a spring. The spring applies a known force as a function of the strain from its neutral unloaded position. A mass on a spring will vibrate in simple harmonic motion, where the period depends on the spring stiffness k, and the total effective mass of the load M. You also have to account for the effective mass of the unloaded machine, that we'll call m0, and the total mass is M=m+m0. The period becomes T=2*pi*sqrt((m+m0)/k). You measure the period when it is unloaded to determine m0, and then you measure the period with the sample mass added to the system, and solve for m. Effectively, it measures inertia instead of gravitational mass. This is how astronauts measure their mass in space. Because we live in a gravitational field, it is much more convenient for us to take advantage of it, by using weight as a proxy for mass. You can either measure the support force in a scale and then divide by the known g-value of Earth to get m. Alternatively, you use a balance with a known reference mass, and compare weight-to-weight.
Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram
But according to Einstein if an object moves with speed of light then its mass increases then how mass is constant?? It is changing with respect to speed....
Colloquially we use weight for both mass and weight. Our weighing machines tell us the mass. The two scale balances in shops compare two weights i.e. two masses

Physics can be easy to understand, since the rules are ultimately objective. We may discover more information about the rules as new physics is researched, but the intent is to simplify it to as few fundamental rules as possible, so that any situation can be understood from the fundamental rules. Many concepts you learn in physics are shortcuts, that can be proven mathematically from more fundamental rules. Such as using the trade of potential and kinetic energy as a shortcut to solve mechanics problems, instead of solving them from first principles like N's 2nd law and kinematics fundamentals. English however, is subject to centuries of evolving social conventions that created a mess of inconsistent rules, and it is impossible to teach someone to always be able to pronounce any word given its spelling, or use that word in a sentence, without a hell of a lot of unnecessary memorization. There are always exceptions to every rule in English.

You can weigh yourself submerged in water to get your body density (out of your buoyancy) and your volume (by water displacement). Volume x Density = Mass
Use a balance instead of a scale. It will measure mass instead of weight, because both the reference masses and the body being measured contain g on both sides of the equation. Take a balance to the moon, and it will still measure the same mass. If you need to measure mass without using a gravitational field of any kind, you can measure the inertia as it responds to a known force. A practical way to do this, is to vibrate it on a spring of known stiffness (k) and measure the period of vibration (T). Using T=2*pi*sqrt(m/k), and solving for m, you can determine the mass. And that is how it is done on the International Space Station.
Oh thanq,because I spend 1 hour on my text to learn this concept but you explain it in just 3 minutes in a best way. Now I think that I will not forget it ever!

شرحك يجنن

Weight - magnitude of gravitational force on an object
Mass - amount of matter inside of an object
Density - the concentration of matter in a particular volume inside of object
in school I used to hate topics like physics and math, thanks to youtubers like yourself I'm rediscovering the joy of learning mathematics and physics. Schools need to be reformed ASAP.
Mass = Quantity of atoms/matter within an object.
Weight = Quantity of atoms/matter within mass/object resisting gravity and inertia.
Gravity and Inertia = Ether/Aether flowing from space towards earths internal electric charge giving all objects on earth its weight.
Your definition of weight is conflating it with inertia, when the term weight doesn't involve inertia.
By your audiovisual presentations things become easy to understand
gravitational is the correct spelling u guys typed/wrote it wrong....v3:30
These types of videos are very good for 9 th standard students😊☺
Inertia = laziness ♨️♨️
Your every topic are very good and your voice makes it easy and helpful to understand the viewer very well

Thanks for your video I was confused with this but your video made know the difference between mass and weight
I like the way she explain because she good at it
Then why do weighing machines calculate our weight in 'kgs' and not in 'newtons(n)'???
Manas Shah because they're in fact calculating your mass not your weight. Hence the unit of measurement is kg not N
@@NeXuzMotionzz yeah, but the video said weight is newtons(n) and mass is kg(s)..Manas Shah got a point. i just think its the manufacture thing.

We measure our weight by weighing machine which shows us the force exerted by gravity on us .so it is weight. But how can we measure our mass
Through a weighing machine...
You can weigh yourself submerged in water to get your body density (out of your buoyancy) and your volume (by water displacement). Volume x Density = Mass
vishnu Sudarsanam your weight / 9.807
Use a balance instead of a scale. It will measure mass instead of weight, because both the reference masses and the body being measured contain g on both sides of the equation. Take a balance to the moon, and it will still measure the same mass.

Should we say my mass is 45 kgs or my weight is 45 N !!!!!!!!!!!!!??????
Ajay Ajay bupp shit question
You should say, your weight is 45kg
From a physics standpoint, mass is kg and weight is N, since it is a force. In everyday life, it doesn't really matter if you say you weigh 45 kg.
according to physics, your weight is 441N. I t is because weight = mass x gravity which is 45 x 9.8m/s. so your weight is 441N.
It is very good. Understanding one. It is helpful for students
