Do two-dimensional objects have weight or mass?

Answer 1

no, two- dimensional objects aren't real in that sense... even a sheet of paper (as close to 2-d as you can get in the physical world) is really 3 dimensional and does have wieght and mass.

Answer 2

Most of the answers here are nonsense.

There are two basic models of the universe at the moment.

The standard model uses point particles (ie points with zero size) and models behaviour of these using wave functions. This leads to some problems.

String theory extends the points to one dimensional strings.

The three dimensional world and three dimensional objects you see in it is a result of these point particles moving in three dimensions.

If they are confined to moving in only two dimensions then they are in effect two dimensional objects.

A good example of this is the electons in the transistors in the computer you are using. These point like particles are confined to move in what is called an inversion layer in the transistor. Never mind what an inversion layer is, it is very very thin.

If you get the transistor cold enough (liquid gas temperatures) the electons do not have enough energy to move at all in the direction perpendicular to the layer. They are then two dimensional objects, and their physics behaves very differently to when they were three dimensional. Howver, they have exactly the same mass, charge and other properties that they had before.

Answer 3

Your question is flawed because everything is 3-dimensional in the universe. The only things that are 2-dimensional are things such as lines drawn on paper, etc. Even a string is 3 dimensional. If you can think of the thinnest thing in the world, maybe a piece of paper, even that has volume.

Answer 4

Every object in the real world is three dimensional. two dimensional concept is only for virtual objects like pictures n paintings n as u mostly see objects in computers.

Answer 5

Name a two dimensional object?

Answer 6

there are not 2d objects, this is only an abstraction made to esaify scientist's work (as are _elastic collision_ _ideal gase_ and so on)
ans every object has a mass (if not it will mean that applying a force F to the corp it will get an infinite acceleration =>it will never stop; or if the object is in equilibrum (F=0) a may have any value and this is not posssible )

Answer 7

There's nothing caled two-dimensional object. In our world the first dimension is time, second is measurement and third is everything around us including us.

Answer 8

no, because weight and mass need 3 dimensional properties. hense the equation for volume must be answered in a unit cubed

Answer 9

BMI would not artwork for individuals that're muscular because muscle weighs more effective than fat does. As you pronounced, Shaq is supposedly overweight in spite of the undeniable fact that that's merely because he's so enormous and muscular. BMI is very well as a demanding handbook on your accepted man or woman, yet you need to in no way use only one device to guage someone's well-being and consistently look into outcomes even as pondering the fellow. different measurements you should use are body fat with assistance from share or body/limb circumferences.

Answer 10

there is no 2-desimal object. if u know tell me.even a 2 dimentional graph is also 3 dimentional although the third dimention is approaching to zero.

all the things that exist are three dimentional and have weight or mass.

we also know that every thing have mass so every thing is 3D as only 3D things have mass
