great vid!!!!!!!

[pasibe85]

This physics professor was awesome!

He explains like my physics professor!

Isn't it beautiful! I don't care on what you read on the scale but It reads the weight of the object attached to it! Isn't Wonderful! How Beautiful Physics can do! haha!

7:24 is the best part

This guy is the loopiest physics professer ever but he's just plain awesome!

[gangbangin69]

dont question the professor,

his authorty is absolute!!!

[ninjajesus81]

He's wrong about how much the water would weigh. It wouldn't necessarily weigh as much as the weight he put into it.

For example, if I had 2 objects that had different weights, but were the same size; if I submerged them both individually in the water they would displace the same amount of water, therefore filling the little bucket the same amount. Obviously the water can't weigh the same as both objects that I submerged since they both weigh different amounts.

[Darkfoster22]

Its not about weight of objects, its about displacement of a mass, is equal to the mass that is displaced.

[pcdsgh]

the equilibrium was set to the mass of the cylinder (and bucket of course). using a heavier cylinder would be fine as long as you reset the equilibrium point.

he's right, and you see that in the video (almost)

Ninjajesus81 How absurd to criticize Professor Miller. A man with decades of experience in the study of physics, a student and personal friend of Albert Einstein! - What are your credentials and associations??? Duhhhhh!

[oreganojones]

Ninjajesus happens to be correct. The amount of water displaced is equal to the volume of the object submerged. So if you have a balloon and a steel ball the same volume as the balloon, the same amount of water will be displaced, but it will not be the same weight as either the balloon or the steel ball, because the water doesn't have the same density as either the balloon or the steel ball. He may be einstein's friend, but, by saying that, he showed that he himself is no einstein.

[xollst]

@oreganojones you're both wrong. he never claims that the weight of the displaced water is the weight of the object, he said that the weight of the displaced water will weigh the same as the force which the water was pushing up on the object. (ie. the force of buoyancy).

it just means that in your scenario, they will both displace the same weight of water, but the balloon is much lighter and will float because it has that much force pushing up on it.

[FlippaIPG]

agreed, the amount displaced of water is equal to the weight that the object would push down by itself without submergence by an outside force, if a person pushes the ball under the water they are adding a force

[apJAzzfusiondruMmer]

nice!!

[needingwinter]

haha i love this guy :P i accually rlly understood and he made it intresting :P I love how he looks like such a physician :P

[disneyprincess1011]

why does something immersed in water seem to weight less?

[pacothetaco556]

because water is acting as a force upward on the object submerged. for instance when you sit in a chair the chair is pushing up the same force upward as your weight sitting down. so the chair doesn't break.

[keeperofthecheese]

surely the level boyancy of an object is affected by the density of the liquid/gas it is being lowered into?

[falco2404]

interesting really good !!!! =D

[muffinman1]

very simple and intuitive experiment that show results. Great !!!

[tracy1010]

The body when immensed in a fluid, experiences an upthrust that is equal to the weight of fluid displaced.
