What does volume have to do with a boat?

What will make a boat hold weight?

How much weight a boat will hold depends on the volume of the boat. This is called displacement. displacement is exactly equal to the weight of the water the boat displaces, that is the boat makes a hole in the water. The volume of that hole times the weight of water (64 lbs for salt water, 62.4 for fresh water) - displacement. The volume of water displaces is equal to the volume of the boat.

Why a wooden boat floats on water?

Well, wood is lighter than water, so it floats, but that has very little to do with why a boat floats. You could make a boat out of just about any material that was rigid enough to hold its shape, and strong enough to not crack under the pressure a boat is subjected to, and, if built to the correct dimensions, it would float. A boat floats because the volume of water it displaces when placed in water has a higher weight than the weight of the boat and everything in it. When you put a boat in the water, it "displaces" (pushes aside) a volume of water equal to the volume of the boat up to the waterline. How much water is displaced depends on how heavy the boat and its contents are. As long as that weight is not greater than the volume of water the boat displaces, the boat will float. But remember, as you place more weight in the boat, it sinks lower in the water, therefore displacing more water, so the weight of water being dispaced is increasing too, though not as fast as the weight of the boat. Eventually, if you keep adding weight to the boat, the boat will weigh more than the water it displaces, and the top of the boat will sink below the water. At that point, water will get inside the boat and quickly add more weight to the boat, causing it to sink rapidly. Another way of looking at it. A boat floats by spreading out the weight of its contents over a larger volume than they would normally occupy, thereby lowering the density of the boat and its contents. This would not work if the boat was a flat piece of wood. The wood itself would float, but you couldn't put much weight on it before it sank. However, if you took that same piece of wood and built a structure (a box with the top side open is the simplest) that had a hollow volume that was prevented from being filled with water, the inclusion of that hollow volume increases volume without increasing weight, which means the density decreases. Ultimately, when you place any object in water, whether it floats or not depends on its density. Adding passengers or other dense objects to the inside of the boat will increase its weight (it will also increase the volume of the boat, if the objects are not fully contained within the volume below the top of the boat, but volume does not increase as much as weight does, so density increases.) At the point where the density of the boat and its contents exceeds the density of the water, the boat will sink. However, some time before that point, the density of the boat will be high enough to push it down in the water enough for water to start spilling over the sides, which will rapidly increase the weight of the boat, with no increase in volume, resulting in a rapid increase in density, causing the boat to sink like a rock. So, if you're looking at in terms of density rather than displacement, you need to assume that objects placed inside the boat, even if they do not fit in the original volume of the boat, do not increase the volume of the boat used in your calculations. In other words, assume that all objects fit neatly inside the original volume of the boat without increasing its volume. So that, when you are computing the density of the boat and its contents, the volume in the denominator remains constant at the original volume of the boat alone.

What is the mass of a aluminum boat?

Mass is entirely dependant on volume and substance, how big is the boat and how much does it weigh?

What paper boat floats the longest?

The paper boat with the largest volume will float the longest basically the largest paper boat will float the longest.

How does changing the shape of the metal affect the density of the boat?

Indeed yes. Density is defined as mass per unit volume. If all the mass were concentrated in one lump, your boat would no longer float. If the metal walls of the boat were a little thinner, you'd have more boat volume, and lower density.

How do concrete boats float?

This all depends on buoyancy of the liquid the boat is in, and the density (therefore the mass and volume) of the concrete boat.

Why does the water level go down when a boat sinks?

When a boat is floating on water it displaces water equal to its weight(Archimedes Principle). As the density of water is less than boat so water displaced is greater than volume of boat. When the boat sinks water displaced is equal to volume of boat. So less water is displaced in 2nd case and consequently water level goes down. Note - relation between volume(v) mass(m) and density(d) : d = m/v

How does a boat stay afloat?

It is lighter than the volume of water which it displaces.

What is the volume of a boat?

you must know the height weight and lenght then multiply them

Do material and shape affect buoyancy of a toy boat?

Yes it does because depending on the materials of the boat and how much their mass is can change the buoyancy of the toy boat. Boat can be designed to have less volume in order for it to have less density and be able to float. So if the material's mass is alot if can make the boat sink. If the material's mass is not alot then it can help the boat float. If the shape is designed to have more volume than mass it will float. If not then it will sink.

Why is it the boat is not sinking if the earth has a gravity?

This is simply because of the weight of the water versus the weight of the boat. The water push upward with a force equal to the weight of the water the boat push away. It is self stabilizing. The deeper the boat lie, the more water it push away, and the more will the water push back at the boat. Of course, if you fill the boat, then it will most likely sink, but here again it depends on what material the boat is made of. If the total volume of materials in boat weigh less than equal volume of water, the boat will still be floating.

Does water temperature affect speed?

Yes, but the effect should be minimum. As water cools it becomes more dense, Meaning that there is more mass per volume. As a boat moves through a given volume it must displace some of the water. Since ( F = M * a ) the boat must exert a certain force to move an amount of water. If there is more mass in that certain volume the boat must exert more force, thereby slowing the boat.
