Is a 1 dimensional object possible?
No. All objects we can make are thee dimensional and there are no exceptions. A thin wire is approximately one dimensional but even the thinnest wire consists of three dimensional atoms. Some quantum objects appear to be point-like however points are zero dimensional.
Is a line 1 dimensional?
A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no “wiggles” anywhere along its length.
Is there such a thing as a 1-dimensional object?
But, The idea of a 1 dimensional object (or a point) is represented all the time in math. If you want to know how an actual tangible thing would exist having only 1 dimension, as far as I know it would be massless.
Is it possible to have a tangible thing with only one dimension?
If you want to know how an actual tangible thing would exist having only 1 dimension, as far as I know it would be massless. Flatland (I forgot who wrote it) is a great book that was written by some mathematician long that deals with observing lesser dimensional objects in greater dimensions.
What is the importance of dimensions in physics?
This simple fact can be used to check for typos or algebra mistakes, to help remember the various laws of physics, and even to suggest the form that new laws of physics might take. This last use of dimensions is beyond the scope of this text, but is something you will undoubtedly learn later in your academic career.
What is the use of dimensional analysis in physics?
Dimensional analysis is used to convert the value of a physical quantity from one system of units to another system of units. Dimensional analysis is used to represent the nature of physical quantity. The expressions of dimensions can be manipulated as algebraic quantities.
