Buoyancy just gives you the static upwards force. The dynamic force while penetrating the surface and moving through the water is complicated, and depends on many factors. But it more likely scales with the cross-section, rather than volume (as the weight and inertia do). So assuming the same density (less than water) and uniform scaling the bigger body will sink deeper.Haizakokaru said:Summary:: buoyancy and force question
Does the higher amount of force exerted onto the water's surface by the heavier person allow him to plunge deeper initially, and then they both sink afterward at the same speed due to same density? In other words, does the heavier person travel a greater distance than the lighter person in a first few seconds of sinking from the water's surface? Does the lighter person not plunge into the water as far as the other?
You can read a bit about it here.Haizakokaru said:Thanks! A friend was saying how much he sinks shouldn't matter due to density and I disagreed, but kept quiet because I wasn't entirely sure about how buoyancy and other forces factored into it. I can finally be at peace now.
Of course, size and shape also play a role. A thin sheet of osmium will likely flutter downward in the water more slowly than a sphere made of ebony wood, despite the metal's dramatically higher density.PeroK said:Something very dense will have a large force of gravity on it compared to the small amount of water it displaces. It's bound to sink faster than something that almost floats.
The weight of a person can greatly impact their diving performance. A heavier person will have more mass and momentum, which can make it more difficult for them to control their movements and maintain proper form while diving. On the other hand, a lighter person may have an easier time executing dives with more precision and grace.
Yes, a person's weight can affect their speed when diving into a pool. A heavier person will have more force and momentum, which can result in a faster entry into the water. However, this can also make it more challenging for them to control their movements and maintain proper form.
There is no specific weight limit for diving into a pool, as it ultimately depends on the individual's physical abilities and training. However, for safety reasons, it is recommended that individuals consult with a trained professional to determine if they are physically capable of diving into a pool.
Generally, a heavier person may be able to dive deeper into a pool due to their increased momentum and force. However, this also depends on the individual's diving technique and experience. A lighter person with proper technique and training may also be able to reach similar depths.
A person's weight can affect their buoyancy while diving into a pool. A heavier person will have more mass, making it more difficult for them to stay afloat. This can be counteracted by proper technique and training, as well as using equipment such as weight belts to help maintain buoyancy.
