equal to their weight
Heavy objects generally sink when placed in water because the density of the object is greater than that of water, causing it to displace less water and sink. For an object to float, it must displace an amount of water equal to its own weight.
Objects float on water when they displace an amount of water equal to their weight, creating an upward force called buoyancy that counteracts gravity. This buoyant force is greater than the weight of the object, allowing it to float. Objects like boats or ships are designed to displace enough water to keep them afloat.
Substances will float on another if the density of the object is less than the density of the fluid it is placed in. This is because objects with lower density will displace an amount of fluid equal to their weight, causing them to float. The concept is known as buoyancy.
the weight of the ship is equal to the amount of water displaced
The objects density has to be less than that of water (which is 1000kg/m3).
The amount of salt required for an object to float depends on the object's density. For example, in water, objects will float when they displace an amount of water equal to their weight. Adding salt to increase the water's density can make it easier for less dense objects to float. The specific amount of salt will vary depending on the object's weight and size.
If an object has a lower density than water, it will float. If an object has a higher density than water, it will sink. This is because objects will displace an amount of water equal to their own weight, and if the weight of the water displaced is greater than the weight of the object, the object will float.
It depends on theplywood density if it is denser then water then you would have to make a shape causing it to displace an equal or greater amount of water in weight for it to float.
An object that is less dense than water will float the best. The shape and size of the object can also affect how well it will float. Objects that are designed to displace a large amount of water will float better than objects with smaller surface areas.
Displacement of water refers to the volume of water an object displaces when immersed in water. Objects that displace an amount of water equal to their weight will float, as the buoyant force of the water supporting the object is equal to the gravitational force pulling it down. This is why objects with less density than water will float, while those with greater density will sink.
Archimedes, an ancient Greek scientist, discovered the principle of buoyancy, which explains why objects sink or float in a fluid. He realized that an object will displace an amount of fluid equal to its own weight, leading to the concept of buoyant force.
If the density of an object is less than the density of the fluid, the object will float. If the density of an object is greater than the density of the fluid, the object will sink. This is because objects with lower density than the fluid displace an amount of fluid equal to their own weight, causing them to float. Objects with higher density displace an amount of fluid less than their own weight, causing them to sink.
