Ships float on water due to the principle of buoyancy. When an object is placed in a fluid (like water), it displaces an amount of fluid equal to its own weight. If the weight of the water displaced is equal to or greater than the weight of the ship, the ship will float. This is achieved by designing ships to be less dense than water, making them buoyant. The shape of the hull also plays a crucial role in providing stability and preventing sinking.

A huge massive ship floats on water but same material ( Steel ) made up of iron sinks because at bottom of ship there is a huge empty space which is filled with air so it makes a huge ship to float on water instead of sinking .
Yes...air is added because it has a very low density which supports the ship. But then what happens to a canoe which does not have air chamber and does not sink. Volume and shape are the first import reason why ship floats.
The reason why ships float is because the relation of Density and Volume is opposite so if volume became bigger therefore the density will become lower and also that's why the ship bottom is almost empty to reduce mass and add more volume to reduce the density which allows it to float (correct me if I am wrong)
A massive steel ship floats in water based on the concept of Archimedes principle. The area of the steel ship in contact with water in much higher so the buoyancy of water is greater and that is why the massive steel ship floats instead of sinking like the steel nail.
@@ogonnaajagu6372 the base of the ship is hollow, you would understand if you have watched titanic, as since the hollow base the volume relatively increases than the mass hence to the formula of density = mass/ volume as volume increases density decreases than the sea water and it floats, however this is not much appropriate according to the higher studies, but it helps to understand density.
Sir please explain about some laws sir like 1)archimedes Principal. 2)Pascal's law 3)Snell's law 4)bernouill's Principal. Sir you have extraordinary talent of teaching
The volume of the base of the large ship is increased so that it can displace more water as the ship displaces water equal to its volume. The weight of water of the same volume is greater than the weight of ship of same volume. So there's create an up thrust force which causes the ship to sail

To answer :- How Does A Ship float in water when a steel nail sinks? Answer :- A ship floats on water because it is designed to displace a large amount of water, creating buoyant force greater than its weight. It also has a "LARGER SURFACE AREA". That is why it Floats.. A steel nail sinks because it is denser than water, so the buoyant force is not enough to support its weight.
You make me understand Physics the most sir. Because of you, i passed my physics exam and I am so happy! Thank you so much sir for putting in the work and making videos like this for us ❤
Q: Why steel nail sink in water and honey and A steel large ship float in water? Answer: 1. Density: Steel nail: A small steel nail has a higher density than both water and honey. Density is defined as mass per unit volume (Density = mass/volume). Steel is denser than water, meaning that for its size, a steel nail has more mass compared to the amount of water it displaces. Since the nail cannot displace enough water or honey to support its weight, it sinks. Large steel ship: Although ships are made of steel, their overall density is much lower. This is because ships are designed with large, hollow compartments filled with air, which reduces their overall density compared to water. The average density of the entire ship (including the steel and the air inside it) is less than the density of water. As a result, the ship can displace enough water to support its weight and float. 2. Buoyancy: According to Archimedes' principle, an object will float if it displaces a volume of fluid (like water) equal to its own weight. The buoyant force pushing an object upward is equal to the weight of the fluid displaced. Nail: A steel nail displaces a very small volume of water or honey, which provides a buoyant force that is not enough to support the nail's weight. Ship: A large ship displaces a significant amount of water, and the upward buoyant force is enough to balance its weight, allowing it to float. SUMMARY: A steel nail sinks because it has a high density relative to the water or honey and does not displace enough fluid to float. A large steel ship floats because its overall density (including air-filled spaces) is less than that of water, and it displaces enough water to generate a buoyant force that supports its weight. "SIR IS THIS CORRECT"
This is because volume of ship is large compared to other materials made up of iron , so as volume increases upward force also increases i.e buoyant force thus buoyance force helps the ship to float on water
Hi sir!I have been waiting for this opportunity to understand floatation and density from you. I love your video explanation. Thanks to you I can understand all the concepts and clear my doubts in a better way. The answer for your question: Though the ship is large and has greater material, it displaces a large amount of water due to which it floats. That is called buoyancy. The upward force is greater due to greate water displaced. That's why it doesn't sink.
There are three reasons for it. 1. The base of ship is wide. So, it will balance itself. 2. It's made of steel. But it's not only steel in there. A lot of stuff is in there having different densities. 3. It's salt water. So, the density is higher than normal. Hope it's right.🙂🙂🙂
As we know that the formula of density is D=m/v and we can see that density is inversly proportional to volume of object and if we increase the volume the density will automatically decrease, so in ship steel's volume is increased and density is decreased so it floats on water
I studied a whole chapter but didn't get the actual and practical meaning of the density but now by the grace of yours i understood each and everything thankyou so much sir ❤️🙌
The reason is due to the large surface area covered by ship in water which provides maximum upthrust force and it is also important to notice that density is inversely proportional to volume therefore ship floats and steel nail sinks.
Ship floats because of buoyount force that pushes the ship upward. Buoyount force is same as the weight of the water displaced by a body. So, If a ship weighs 100000000 kg f then the buoyount force will also be 100000000 kgf. BTW love the explanation.❤
Its basically due to large surface area, since volume is associated with the size and shape so when mass is divided with a large number it will give a small value resulting in less density. Larger surface area or more volume means less density
The skip floats as the weight of the ship by its unit volume is lesser than that of water so even if an elefante is kept on top (if the ships material can take the weight) the ship will still float as the density will still remain lighter than 1g/cm^3
The volume of the ship where touches the water is extremely high. If we take the exact same amount of water which is equal to the ship's sinking volume, it should be weight way more than the ship. That's why the ship floats on water. According to Archemedis :)
i have a question , people say when people add poison to your drink that have ice , the ice will sink , so does that mean the added poison will add more density to the ice and then make the ice sink?
Because the steel Ships Surface Area is more. More the surface area of the object (i.e, the steel ship).More the buoyant force experienced by the Ship. So, more the Surface area of the object = more the Buoyant force of an object..

Though the Density of plastic material used in that orange ball is 0.98 g/cubic cm, it doesn't sink in the kerosene because the average density of orange ball is reduced by filling air with it. Same concept is applied in ship also Though materials used to make ship has higher density than water, average density of ship is reduced by filling the air within it. At last, density of ship becomes less than 1 g/cubic cm and so it floats in water.
Thank you sir. If my school teachers were this good I would not hate studying this much. You are the best teacher sir. And also please try to make courses on class 11
For the bottle cap to float in kerosene it had to be filled with kerosene and would be floating otherwise. You should have filled it with water too to see if once filled it would still float above the water.
Ships float in water due to their hollow built in structure which is naturally built in a way like that. Iron needles are more compact and it's density is 7.8 g/cm3 the density of iron needle is more than 1 g/cm3, it sinks in water but an iron ship's density is way more less than 1 gm/cm3 hence it floats on water.
The iron steel ship floats on water because the density of water is directly proportional to weight of liquid if weight will increase and density could also increase, the mass of boat is less than the mass of water that's why it's float on water
Ship(made of steel) floats on water because the density of the water is greater than of the ship. Due to large coverage of the water. Please reply to me so that I will know if I'm right.
Even though the ship is large;larger than the nail, the inside part of the ship is hollow.the hollow space is filled with air: hence it reduces the average density of the ship to lower than that of the water.since the density of the ship is less than that of water,it floats on the water
The volume of ship is much.And volume of a body is anti proportional of density.The density of ship become less than water due to its large volume and that's why it floating on water
An iron nail is a totally solid object while a ship is hollow from inside and contains air. So, the average density becomes less than water and the ship floats.

🎉 ocean water is salty which increases the density of water therefor ship float on it
No
Yh that’s wrong
@@nazeerkhan3303 really
It is right
10:14 this process occurs based on buoyancy as the steel ship has a greater surface area the higher the buoyancy
Right! You can also explain it in terms of density: since ship is hollow, average density of steel ship is less than water.

Q: Why steel nail sink in water and honey and A steel large ship float in water?
Answer: 1. Density:
Steel nail: A small steel nail has a higher density than both water and honey. Density is defined as mass per unit volume (Density = mass/volume). Steel is denser than water, meaning that for its size, a steel nail has more mass compared to the amount of water it displaces. Since the nail cannot displace enough water or honey to support its weight, it sinks.
Large steel ship: Although ships are made of steel, their overall density is much lower. This is because ships are designed with large, hollow compartments filled with air, which reduces their overall density compared to water. The average density of the entire ship (including the steel and the air inside it) is less than the density of water. As a result, the ship can displace enough water to support its weight and float.
2. Buoyancy:
According to Archimedes' principle, an object will float if it displaces a volume of fluid (like water) equal to its own weight. The buoyant force pushing an object upward is equal to the weight of the fluid displaced.
Nail: A steel nail displaces a very small volume of water or honey, which provides a buoyant force that is not enough to support the nail's weight.
Ship: A large ship displaces a significant amount of water, and the upward buoyant force is enough to balance its weight, allowing it to float.
SUMMARY: A steel nail sinks because it has a high density relative to the water or honey and does not displace enough fluid to float.
A large steel ship floats because its overall density (including air-filled spaces) is less than that of water, and it displaces enough water to generate a buoyant force that supports its weight.
"SIR IS THIS CORRECT"
This is because volume of ship is large compared to other materials made up of iron , so as volume increases upward force also increases i.e buoyant force thus buoyance force helps the ship to float on water
The weight of water displaced by the ship is more than the weight of ship, hence the ship floats; Archemedes Principle
Iam studying 9th standard. Ive understood all the concepts in mpc becaue of your videos sir. Glad to have a teacher like you.😊😊😊
You are the legend real way of teaching
Thanks a lot!
Since the ship is hollaw , it's mostly surrounded by air which is less dense compared to the density of the water in sea /ocean/lake
This material was very helpful and now my students understand the concept of Density and for this I thank you.
Hi sir!I have been waiting for this opportunity to understand floatation and density from you. I love your video explanation. Thanks to you I can understand all the concepts and clear my doubts in a better way.

The upward force is greater due to greate water displaced. That's why it doesn't sink.

There are three reasons for it.
1. The base of ship is wide. So, it will balance itself.
2. It's made of steel. But it's not only steel in there. A lot of stuff is in there having different densities.
3. It's salt water. So, the density is higher than normal.
Hope it's right.🙂🙂🙂
The last question in each video always makes me rack my brain everytime and remember the concept better . THANK YOU sir🎉😊
Glad to hear that
Many thanks -- really appreciate how to make everything easy to learn
Thanks a lot...
My all doughts get cleared by seeing this viedo 😊
As we know that the formula of density is D=m/v and we can see that density is inversly proportional to volume of object and if we increase the volume the density will automatically decrease, so in ship steel's volume is increased and density is decreased so it floats on water
Plz mix them and upload lecture on volume
I studied a whole chapter but didn't get the actual and practical meaning of the density but now by the grace of yours i understood each and everything thankyou so much sir ❤️🙌
The reason is due to the large surface area covered by ship in water which provides maximum upthrust force and it is also important to notice that density is inversely proportional to volume therefore ship floats and steel nail sinks.
I am just a 4th class girl and u made me understand everything sir!!
Ship floats because of buoyount force that pushes the ship upward. Buoyount force is same as the weight of the water displaced by a body. So, If a ship weighs 100000000 kg f then the buoyount force will also be 100000000 kgf. BTW love the explanation.❤

water exert a bouyant force on submerged object.
Thanks a lot of with gratitude to upload such interesting video 🙏🙏🇮🇳Jai Hind
This is because it is made hollow inoder to make the boat less dense than water
In the ocean water the salt aslo dissolved and make the density more and the shape of the ship is made by Archimedes principal
Because the surface area of boat are increase then it flow in water and we know that density is also depend on surface area of objects...
i have a question , people say when people add poison to your drink that have ice , the ice will sink , so does that mean the added poison will add more density to the ice and then make the ice sink?
Because the steel Ships Surface Area is more.
More the surface area of the object (i.e, the steel ship).More the buoyant force experienced by the Ship.
So, more the Surface area of the object = more the Buoyant force of an object..
It is based on Archimedes principle
please make a video for principle of flotation 🙏 🙏
It is because iron made ship displaces a weight of water equal to its own weight, it floats.This is principal of floatation
Yes absolutely correct
If all Teachers Teach like u ,we'll learn more and more .please keep your Teaching
weight of water displaced by the submerged part of the ship is very high in this case thus, the upthrust is high resulting in flotation of ship)

Though materials used to make ship has higher density than water, average density of ship is reduced by filling the air within it.
At last, density of ship becomes less than 1 g/cubic cm and so it floats in water.
