Density reduces due to increase in buoyant force acting opposite to the weight of the person (so the net mass gets reduced)

[sanskritikri.]

A LifeJacket, however, is made of lightweight form that weighs much less than the average weight density of human beings. As a result, when a person is wearing a LifeJacket,  the total weight to be displaced by the water is much less as compared to the weight of the person alone, and so the person floats.

Thank you ma'am for this information, I love ur teaching 😘💟

[ShreyanshSharma_]

Very nice
Thanks for explaining in very easy way👍👍👍👍👍

Density of person doesn't changes.
Only the volume of person with life jacket increases.

[simranjitkaurphhpchd]

You always give fantastic information 😊

[navishkaroy]

As explained, the life jacket is made of foam that weighs lesser than the density of humans. Hence, when you wear a life jacket, the weight which is supposed to be displaced in water is less or reduced in comparison to the weight of our body. That is why we float while wearing a life jacket.

Density of the person wearing the life jacket is much much less than the original mass per unit volume. When wearing a jacket, the volume increases making the Density decrease. (D♾1/V)

Nice explanation Tarana mam please make more videos like this 😊

[AAA]

Thank you mam for this wonderful video.
I had always been thinking but today I got to know this. 😊😊

[Ravi_Raj.]

Density of person changes becoz the volume increases after wearing this life jacket but the mass in almost same as before so mass/volume = Density.
So the Density of the person decreases.

[hiramanisahu-dspj]

firstly I am confused about the question how density change of a person while he was wearing a jacket
maybe the answer is because when the person main to jacket it's part of the body and then it looked like wait push down the person inside the water but because of the phone and the jacket it float up words

[soupermythos]

density decreases as area of contact increases and vice-versa

[by_justice]

density is mass/volume. Mass is constant but volume isn't. It changes hence density of a person keeps changing!!!!

[harshvardhan_Jmi]

Density reduces as volume increases without considerable increase in mass

[AWESOMEGAMING]

Thermocol have less mass so less density, so density of thermocol<density of water . So we floats on water

HAPPY INTERNATIONAL BIODIVERSITY DAY TO EVERYONE IN THIS WORLD 🌍🌎🍄🌱☘️🌱🍄☘️

[XBET-cwdc]

Density Is CHanged As The Mass Is Decreased While The Volume Is Increased, This Will Help Us Becoming Less Dense And Ultimately Floating On Water.

Informative Btw..

[amartyajha]

Then how do humans can't float without floats

[eraofknowledge]

Density of jacket with man is less density wrt to water
