I've watched many videos from your channel whenever I got problem on my understanding what my lecturers taught, and know i understand after i watch ur videos, so thank you very much
I've been watching your videos almost non-stop the past few hours. I only discovered them yesterday - so wish I'd discovered them sooner! Science of any kind doesn't make sense to me (more into math and writing) and your videos, I can say with total confirmation, are the only reason I'm currently able to grasp any of these concepts. I'm literally having to learn an entire semester's worth of work in one week for my final exam, and it's all thanks to your videos! I cannot thank you enough!
Idk at what level you are studying but math turns into science when you reach the university level. So i would recommend you to get your basics in science brushed up
@@Sibasish07 college and I only need a basic physics class for my major. Most of my major is electronics, and that I get. But science? Not so much... thanks for the advice, though!
I want to say thank you very much you let me clear in15 mins while some teacher use your videos to teach me and some of teacher teach 2-5 period in some topic thank you very much for making these videos. // from thailanddd
really loved that explanation of boyancy with the cylinder in the deep / shallow water.. this is my life now, getting excited about understanding science - I'm ok with it
well tbh im watching this since our uni teacher put in for the entirety of the course your videos and some other, i think khan academy. Im glad but i would have wanted to have a real f2f teacher....
I can't explain it theoretically, but no- the unit of volume is m³. Mass × density would be kilogram × kilogram per metre cubed and work out as kg²/m³. In physics, as a general rule, if the units don't work out then the formula is wrong. Don't want to say too much and ill-advise you, but hope that helped :)

Sir I have some few question about density and buoyancy force No. 1 =Is hot water more dense or cold? i think cold is more dense. No. 2 = if cold water more dense what it mean is it more buoyancy?i think cold water more buoyancy. No.3 =if cold water more dense so does it help for swimming easily? i think cold water help swimming. No.4 =is water more dense mean more buoyancy easy to float or less dense mean less buoyancy difficult to float?
1. Cold water is denser. 2. Don't qoute me on this but I think it depends on the density of the object 3. Yes, but the increase in buoyancy is minimal 4. Again I think this depends on the object being submerged.
Is there any topic that is connected to this lesson? Of course the video is good, nothing wrong but myself, I didnt understand. LOL I HAVE ONLINE FINAL EXAMINATION THIS WEEK.
You mentioned Fb is F2 - F1. It means F2 is greater than F1. How can FB be in the upward direction? It has to be in downward direction right? Am I missing something in interpretation 🤔
Can you explain to me why a cylinder or container that has a vacuum in it wont float? Or to put some context to it, why do we use helium to float a blimp (I get that) but we don't use an internal vacuum instead of a gas?
Wouldnt the water above the immersed object exert pressure upon it? It actually supports the water above it? Or does the ground under the object support the water above it? Can i send you drawn problems which you may solve and explain to me logically.
man i just love u so much. all hail the king of teaching. BTW i really love ur voice. no homo. it gives me ear gasm laughing my fking ass off laughing our loud
a) A floating platform is to be anchored in one of the water-sports lake areas to be used as mooring pontoon for safety and rescue boats. It is proposed to anchor the platform to the lake-bed using a makeshift anchor consisting of a lump of cast iron of volume0.5m3, and a length of thin steel cable. Assuming the cable remains vertical and has negligible weight, calculate the tension in it due to the anchor.Take the cast iron density to be 7850 kg/m3 and the density of water to be 1000 kg/m3. can you help me with this please?
I have a question. So the gravitational force is equal to the bouyancy force (Fz = Fb), but the block and water have two completely different densities, so how does that work?
hi sir, first of all thanks for the video, it really helps! but i'm confused about the 9:49 part. isnt the V the volume of the silinder? and the density is the densiry of the water right? then how come the two of that multiplied equals the mass of the fluid?
マルコデイブ physics is arguably the hardest of all, even than math; one day you will have an eureka moment when everything make sense; sound silly but that true
Yeah like when I was a child math was so hard until I am a high school it seems very easy for me... So adults have a capable brain for physic well thanks for cheering me mate lab ya
What is the box is a open metal box of 20 tonnes? When submerging water will go inside the box... do we have to add the weight of the water + the weight of the metal box?
😇what if the a question was like this [A 10.0-kg block of metal measuring 12.0 cm, 10.0 cm and 10.0 cm is suspended from a scale and immersed in water as in Figure 1. The 12.0- cm dimension is vertical, and the top of the block is 5.00 cm below the surface of the water. Take P_atm=1.013×10^13 N/m^2 and ρ_water=10^3 kg/m^3 i. What are the forces acting on the top and on the bottom of the block ii. What is the reading of the spring scale? iii. Show that the buoyant force equals the difference between the forces at the top and bottom of the block.] how can one answer it.
Something doesn't add up. According to your diagram I thought it must mean if you have really long cylinder, it must exert larger buoyant force if it's vertical than horizontal, as if it is vertical, lower end would be deeper therefore experiencing bigger pressure. Turns out it does, but at the same time, it has smaller area than if it was horizontal so overall force is the same... by coincidence? Isn't that just super neat if you would define variable on which you would rotate that cylinder, and you would define buoyant function at every point of this variable, every time it would cancel out perfectly, that's way too clean, there must be some process in the background that I don't get. And yeah I know it just wants to be replaced by the same volume of water but that is just consequence of this calculation, not the cause. I will not be satisfied by some vague notion of sentient water that feels something is in it's way. I'm looking for deeper process like to explain why is everything falling at the same rate. According to Newton it was coincidence, that mass would cancel with inertia PERFECTLY, well Einstein found out not really, things are actually stationary and spacetime is curved - something like that.

Hello i have a doubt
that mg +the F1 would be acting downwards ?
I have a question. So the gravitational force is equal to the bouyancy force (Fz = Fb), but the block and water have two completely different densities, so how does that work?
Which law of motion does upthrust force related please
You are a God!
Please increase volume
you are amazzzzingggg
hi sir, first of all thanks for the video, it really helps! but i'm confused about the 9:49 part. isnt the V the volume of the silinder? and the density is the densiry of the water right? then how come the two of that multiplied equals the mass of the fluid?
Well yeah V is the volume of the cylinder, but that also makes V the volume of the water it displaces, which is what you need to calculate
so in the first example we are working with liquid oxygen? since I think air at room temperature is gas, but im not sure.
Thanks for explaining and still I don't get it I'm so dumb huhu

You probably cant do basic algebra so good luck becoming the next newton. 🙂
If the net force is the buoyant force the object should go out of the water i don't think it is a net force
