How Buoyancy Works: The Science Behind Floating in Water Explained!

- Have you ever wondered why you float in water? This video delves into the fascinating science behind buoyancy, the upward force that allows objects to float in a fluid. You’ll learn about the factors contributing to buoyancy, including water pressure and density, and how the buoyant force is calculated. We’ll also discuss how buoyancy is related to the weight of an object and the amount of fluid it displaces. Whether you’re a science enthusiast or just curious about why you don’t sink in the pool, this video will give you a clear understanding of the principles of buoyancy. #buoyancy #physics #scienceexplained #floating #waterpressure #fluidmechanics #weight #density #upwardforce #displacedfluid #swimming #poolscience #educational #sciencefacts #STEMeducation #learning #curiosity #funfacts #sciencevideos #CZcamsScience #science101

Ig I go against the laws of physics, because I simply sink no matter what
It's to do with your ancestors, white people can do it somehow
but isn't it part of laws of physics?
Therefore ur weight is more than the buoyant force acting upwards
It's because you probably take water in your mouth or your nose which increase the density of your lungs and therefore you sink
Me too
Perfect
Now i know how they died in the submarine
Tq u explain it very easily
But when i get out I feel 100 pounds heavier
Yea😂me too
@@naishaarora1498 because you are, with a lot of water around you so you are heavier
What if there is no liquid at the bottom of the object, just on sides - it sits on the bottom of the pool, will it still be effected by boyancy force the same way?
❤
but is it the same with a human body and a wooden crate? since we are mostly made of water !?🤔 just thinking out loud...
I like that you’re thinking about it! Always feel free to ask questions, those of us in these types of fields love to hear people take an interest. Just as food for thought, the average human body averages a density of around 985 kg/m^3 and with a full breath around 945kg/m^3. Fresh water is 1,000kg/m^3. So, on average, because your body weighs less than the water you displace you will float. If the wooden crate is full of air it likely weighs less per unit volume than you and will also float in the same water, the difference is that since you are very close to the same density
someone could easily sink you with just a little force. The crate will be much more difficult to sink.
@@garrettnelson2293 thanks for taking time to explain this ... ✌️
Why buoyance force is equal to weight of displaces water
The reason is that the fluid, having a higher density, contains more mass and hence more weight in the same volume. The buoyant force, which equals the weight of the fluid displaced, is thus greater than the weight of the object. Likewise, an object denser than the fluid will sink
Sir, which object's density is used in this equation? Displaced fluid or the buoyant object?
Hi can u help me with one doubt
An object sinks when its W is more than the buoyant force right but also another thing I know is that when the density of the object is more than the density of the liquid it also sinks
So what's the difference between these 2 statements
They both are true right
@@hiranjana7474 yes
@@v_gigaharz Thank you
The density of the fluid.
I always go down
skill issue
You are negatively boyant. It could mean that you have heavy bones, hence you don’t naturally float.
@@IranAzadLoadingis that why people drown 😭
@@crpzez heavy bones, low body fat, muscles can all be reasons.
Or all the above, but heavy bones is primarily reason.
I got it.
I don't float tho. I sink, like no matter how hard I try to move my hands and feet to try and keep at the surface, I don't. I just sink.
I dont get it
