Today I learned about buoyancy which is the opposite of gravity, let me explain. Some things float and some sink because of something called density. Density means that some objects have molecules that are packed together which are more dense and some objects have molecules that are loose which have less density. A example is if you put a ice cube in a glass of water it would float because gravity is pulling it down but buoyancy it pushing it up so it is slightly under water and slightly above water. And it would be easier carry something heavier in water than something lighter in water. That is a little bit of what I learned today about buoyancy. Bye

Just now I learned about buoyancy.Buoyancy is basically the complete opposite of gravity. Somethings float and some thing sink because of something called density density means that some Objects that have something called molecules that are together which are more dense and some objects have molecules that are kind of loose which means they have less density. That’s what I learned Bestie’s.

It means that certain things will flow in certain things will not float for example a rock will sync a pencil of stay afloat a shoe would think a mask would not it’s just like the mask the heavier it is the more quicker it will sink that’s all I really know bye-bye

Buoyancy Is something that holds something still or to float. The titanic sank because there was to much water going in the back. The titanic hit the iceberg and it scratched the side of it and that is how thw titanic was sank. Here were some facts about Buoyancy.

Density is what it is tiny molecules density means packed together stuff that is packed harder has more density but stuff packed loosely has less density. En example is when a boat is in the water how they stay afloat is think like the boat 🚣♂️ pushes the water away as it can stay afloat in the water 💧 a different way to think of it is gravity pushes down wile water pushes up ⬆️ so that is how it stays in the middle becouse there are to different things pushing it. That is all so by ✌️

Today I am going to be talking about buoyancy buoyancy goes up and gravity goes down and all the water filled up to the end there was so much weight on the end but the beginning didn’t have that much weight as the back did so in sync by the backSo they move up or down same object is with things that are underwater. A lot my Besty’s died 😭😭😭😭😭😭😭😭😭😭😭😭😭

So from what I understood from the text and video, buoyancy is some form of gravity in water like if a object is hollow on the inside, it would float and objects that don’t will sink. And I don’t think it matters how big or small the object is too! That’s all I really understood in the video and text given. 😅

Today we’re learning about how things float and sink. Density is what cause somethings to sink and float. What does density meant? Well everything is Mary up of tiny molecules. Sometime the molecules are jam packed together, and in others they are lose packed tighter. This is actually what density means. The objects that are jam together have a higher density and more loosely packed objects aren’t as dense. Some objects don’t sink because of gravity. Like boats or ships. But some objects don’t. (The titanic sunk because of a iceberg not because of density). What is buoyancy? It’s the pushing and pulling forces. That’s the end of my day text ⚜️⚜️⚜️⚜️⚜️⚜️⚜️⚜️

Today i’m going to talk about bouyancy. Bouyancy is the opposite of gravity it pishes things up instead of down that is how the titanic was able to stay afloat it was also because gravity was pulling it down. Density is whether or not it is heavier then something else. If you were to put a ice cube on water the ice cube would have a bigger density than water. And that’s what I leaned about bouyancy.

Buoyancy is the opposite of gravity. Density makes things sink and float. When something sinks it has molecules that are packed together. When something floats it has molecules that are loosely packed together. For example a boat stays a float by pushing the water aside to make enough room for itself. Another example is if you put an ice cube in water it will move the water to make room for itself, the effect is the water level will rise causing the ice cube to move up and down.

Today I’m going to talk about buoyancy and why it is different from gravity. To start off, gravity makes things go down and buoyancy makes things go up. So you probably are wondering how the titanic’s stayed afloat (for a while). It stayed afloat because of buoyancy. As I said before points he makes things go up. And when the titanic was put on the water it pushes some water away so it can make room. It also state of flow by it’s generous propellers. For another example, a pencil and it pushes the water away so we can make room and then gravity is pulling it down and buoyancy is pulling it up so it is constantly moving up and down in the water. There are some things I learned about buoyancy.

The reason some objects sink and some float are because of density. Density is how much molecules are in that certain object. If it has more density it will sink if it has less it will float. Buoyancy in the opposite opposite of gravity buoyancy is the force the makes things rise. That’s why things can rise when they,re in water.

Today we will be talking about buoyancy or how things sink and flout let’s begin already so density is a big part of it density is what makes it sink or float well what is Density exactly density is tiny itty-bitty molecules which are either packed together really tight or they are very loose and the ones that have more density are really jammed together The ones that don’t have as much are really loose.What is buoyancy well buoyancy It is pushing and pulling forces like how gravity pulls things down.

Buoyancy is something that can float in water or air. Also buoyancy is the opposite of gravity. I’m going tell you what causes some things to sink and float. It’s about something called density. Density means objects that are packed together have a higher density. Now let’s talk about boats that are massive. The boat has to push the water side so that there’s room for it. When it’s so heavy it actually gets pulled down by the force of gravity. Things that float has less dense in the water. If you put objects together in a jug of water you will see what floats and what sinks to the bottom of the jug. The objects at the bottom are more denser than the objects that floats at top of the water. Some ships float at different heights depending on how heavy they are and how dense the water is.

Boyancy is the force that acts on gravity. Let’s take warfare for example ok ok I know what you are thinking warfare is violent. But I use it for referance because boyancy is shoving on gravity and so is gravity on boyancy. That is basically warfare now boats float because of boyancy PLUS the water and here is some fact: boyancy makes us float right? Well go into your pool in summer and just try to float. How do you think we can do that? Boyancy is the answer. Some things sink because they get WAAAAAAAAAAY to heavy and gravity wins the war.

Buoyancy is upward force of water better known as the opposite of gravity. Also buoyancy matters about the density of the object whether is a ping pong ball or a cruise ship, they all have density and density means how much mass is in one area. To explain this I'm going take the Titanic for an example because when the Titanic scraped the iceberg, water started to flood the front and the water - tight compartments so the front had more density than the back which caused the Titanic to snap in half.

Today I learned about buoyancy is The opposite of gravity. Somethings sing and somethings float because of density. Can you say example of density it is something that has monocles with is loose with has less density. And if they are packed together they have more density. Her is a example if you put crushed ice cubes into a cup it will float because of gravity is pulling down so buoyancy will go up slightly so it is slightly above the water. It will be easier To pick something heavy in water then something light. The Titanic sink because of the ice burg from filling up more than four slots so it sang. That is what I learned today by.

This is what buoyancy is. Buoyancy is basically the opposite of gravity. Gravity is the force that makes things fall down. Buoyancy makes thing go up. Objects float because of the density it has. You can tell if the object has lots of density or barely and density if you try to make it float. if the object floats it has little density but when it sinks it means it has a lot of density.

Buoyancy is the Force in water which is basically the opposite across but it’s the or some water samples something to go underneath the ocean. Buoyancy is what causes things to float and things to sink. Destiny means items or things that are like compressed together and it makes him have a higher destiny. Even though the titanic was very dense and full of destiny it’s still floated for a lite bit of time because their hulls are full of air. And the reason that the titanic sink it’s because once the iceberg hit the ship it created a hole and the hole in the ship let water go onto the ship and then gravity started doing a job by using a bunch of water term to drag down the boat.

Buoyancy is the opposite of gravity. This is how the titanic sank because the water had buoyancy in the front and no buoyancy in the back and that is the reason why the ship snapped in half. What is buoyancy you say buoyancy is when it’s uneven because if there is too much water in one of the side then it will snap in half. If there is no buoyancy then it will not snap in half then it’s not even will gravity. That why something float and something’s don’t.

To start off, floating requires two forces, gravity and buoyancy. Buoyancy is the opposite of gravity. It is an upward force that works against gravity to keep something afloat. When the titanic was made it hade big compartments of air to help keep it floating. While gravity is pulling it down into the water buoyancy pushes it up. Some objects float because it has a small density, but if the density is heavier than the water it sinks. But if the object weighs less than the water it displaces then it floats, on the other hand if the objects weighs less than the water it displaces than it sinks. So for example an ice cube would weigh more than water so when you drop it in water it takes the space of some of the liquid and floats. So the titanic weighed more than the water it replaced and it floated.(until it filled with water in the front and it started to weigh more in the front so it sank.)

Okay soooo... Bouyant force pushes upwards and the gravity force doesn’t. So the titanic was full of air pocket things and water went in them and that’s heavier then air so it made the gravity pull the ship down. Density is like tiny molecules and the packed together ones have a high density lower have low density!

Hello today I’m going to tell you what I learned from the video and article 🤗.first what is density? Density is basically made up of teeny tiny little molecules that makes things float 🛳. On the titanic the ship sunk because it hit a iceberg and scraped the side it made the bottom of the boat loose the buoyancy speaking off buoyancy what is buoyancy? Buoyancy is the opposite of gravity. The titanic floated because it had big compartments full of air at the bottom of the ship.this is all that I learned from the article and video.

Buoyancy is water pushing up on thing that are less dence than water. Somethings sink because they are more dence than water so gravity pushes them down under water. The titanic sunk because when it got hit by the iceberg the titanic got a hole. The titanic’s hull filled up with water making it more dense.

Buoyancy is the opposite of gravity. Buoyancy has a force called buoyant force. Buoyant force is the upward force of Excerting object by the liquid the object is in. The buoyant force pushes upward while gravity pushes downward . For example, the titanic hit the ice berg and started to sink but the back part was sinking in water the front was still up .

What is buoyancy? Well buoyancy is the exact opposite of gravity instead of pulling down it pushes up. Now you know a buoyancy is. To make sure you know what it is they give you some examples. Number one when you put ice cubes into water it stays afloat but how gravity is pushing it down. What happens The ice cube has to push the water out of the way making the water rise.Now they know what it is for sure. Why do some objects stay afloat while others sink? Like when the titanic slammed against the iceberg it made a hole underwater and it filled up with water . But if it floated at the beginning but then sank. What happened is water is heavier than air so the more it filled with water the heavier it was pulling it under and sinking it .Hopefully all your questions are answered hopefully you have a wonderful day

To begin, buoyancy is a force that pushes up against the gravity and makes room for itself. Buoyancy starts when a item is in water and it has mostly air in it so it then will float. How things float is depending on how dense the water is if it is fresh water then the item will be sinking faster or floating lower because it is less dense, if it is salt water the item will sink slower and the item could also float higher because of the salt it is more dense. It also depends if the item/boat is made of different materials the main material that sinks on its own is metal and the material that usually floats is wood.

What is buoyancy? Well, buoyancy is the opposite of gravity so if gravity pulls something down to earth (literally) then buoyancy pulls it up. So why did the titanic sink? So the reason why was because of its density, so when the titanic was afloat the the power of buoyancy are fighting for it and this is where density comes in. So density is when an object is packed tight or soft. If the molecules are more spread out it has a lower density so it will float but if the molecules are more closely packed then they have a higher density and if it has a higher density it sinks but if it has a lower density it sinks. For example the titanic snapped in half when it sank one side was more heavy and more dense and it sunk and the lighter less dense part of the ship stayed at water level so, when the heavier part below the water level it was pulling against the floating part and it snapped in half. So now you know why things float and others sink, and what density is.

Today I’m talking about botany and why things float and others don’t. First buoyancy is we’re a objects moves the other stuff around to make room for them. Second you know how people say that big things sink and little things float well that’s incorrect the right answer is how much density it has. Density is we’re loosely and tightly packed molecules come in. If the packed molecules are tight then they have a higher density and if the packed molecules are loose the they have a lower density. Higher the density it will float lower the density it will sink.

Today our blog is based on buoyancy. First off, buoyancy is basically an ability to float on water, air and more. Why do some objects sink and others float? Something called destiny is the cause of the objects that sink and others float, you may ask well, what is destiny? Destiney are tiny molecules all around us, so basically destiny is why some objects float and others sink. That is what I’ve learned from the article.

Boyency is a force to do with how some things float on water and how somethings don’t float on water. For example a boat floats on water but if the ship snicks it is because it hit something and the upper force goes down first because it is the heaviest part of a boat and if it doesn’t sinck it is because gravity is holding the weight of the front of the boat. That is what boyency is.
