A cork is able to float on water because it is?
A cork is able to float on water because it is less dense than the water. The reason why is because an object with more dense then itself it will float and an object with less density will sink in the fluid. HOWEVER if the object (such as the cork) has the same density, the object will neither float nor sink; instead it will stay at the same level in the fluid. So TECHNICALLY it is considered floating. So corks count as floating because it has less dense than the water. Sources: (Science: Glenco textbook)
If two objects have the same density does it float are sink?
The previous answer was incorrect. Whether or not it will float has nothing to do with density being more or less than one. If an object is of the same density as the fluid, it will float just beneath the surface of the fluid, because the buoyant force is exactly equal to the object's weight. (which makes sense, because buoyant force is equal to the weight of the volume of fluid displaced by the object, and the densities are equal. Remember, density=m/V!) This results in a net force of zero (buoyant force pushes up with exactly the same magnitude as the weight vector, which points down, so they cancel out), meaning there is nothing to cause the object to sink or float.
How does density affect buoyancy?
Density affects buoyancy by determining whether an object will float or sink in a fluid. If an object is less dense than the fluid it is in, it will float; if it is more dense, it will sink. Buoyant force acts in the opposite direction to gravity and is stronger when the density of the fluid is greater than the density of the object.
What is the amount of fluid pushed aside by an object called?
The amount of fluid pushed aside by an object is called the displacement of the fluid. It is equal to the volume of the object when it is immersed in the fluid.
How are density and buoyancy are alike?
Density and buoyancy are related in that they both involve the concept of mass per unit volume. Density is a measure of how much mass is contained in a given volume, while buoyancy is the upward force on an object placed in a fluid, which depends on the object's volume and the density of the fluid. Both concepts play a role in determining whether an object sinks or floats in a fluid.
