The average density of an object is what ultimately determines whether it floats. If an object’s average density is less than that of the surrounding fluid, it will float. The reason is that the fluid, having a higher density, contains more mass and hence more weight in the same volume.
30 Μαΐ 2024 · Determine the volume of displaced water by dividing the mass of displaced water by the density of water, i.e., 1000 kg/m 3. This value is also the volume of the object. Find out the object's density by dividing its mass by volume.
The fraction of an object’s volume that’s submerged is given by the ratio of its average density to that of the fluid: \(\mathrm{\frac{\bar{ρ}_{obj}}{ρ_{fl}}}\). An object floats if the buoyancy force exerted on it by the fluid balances its weight.
Course: AP®︎/College Physics 1 > Unit 6. Lesson 2: Buoyant force. What is buoyant force? >.
16 Αυγ 2021 · Stated in words, Archimedes’ principle is as follows: The buoyant force on an object equals the weight of the fluid it displaces. In equation form, Archimedes’ principle is. FB = wfl, (6.6.1) where FB is the buoyant force and wfl is the weight of the fluid displaced by the object.
16 Σεπ 2024 · Here a 5-kg object immersed in water is shown being acted upon by a buoyant (upward) force of 2 kg, which is equal to the weight of the water displaced by the immersed object. The buoyant force reduces the object's apparent weight by 2 kg—that is, from 5 kg to 3 kg. (more) Archimedes’ principle. physics. Written and fact-checked by.
In equation form, Archimedes’ principle is. F B = wfl, F B = w fl, where F B F B is the buoyant force and wfl w fl is the weight of the fluid displaced by the object. Archimedes’ principle is valid in general, for any object in any fluid, whether partially or totally submerged.
