What Is a Non Linear Relationship? | Sciencing
GRAPHS IN PHYSICS 1. Published in: Education, Technology Non Linear Relationships Not all relationships between variables are. Nonlinear phenomena in solid state physics and technology The introduction of dispersion into the nonlinear wave equation results in stationary wave. The distinction between linear and nonlinear phenomena is everywhere The equation y = x, for instance, is equivalent to a function that takes as its input a nonlinear systems, because arbitrary things can satisfy that definition. Topics: Computer science and technology, Computer Science and Artificial.
However, most of them can still fit into other categories, like polynomial, logarithmic, etc.
The side of a square and its area are not linear. In fact, this is a quadratic relationship. If you double the side of a square, its area will increase 4 times.

While charging a capacitor, the amount of charge and time are non-linearly dependent. Thus the capacitor is not twice as charged after 2 seconds as it was after 1 second. This is an exponential relationship. Studying Non-Linear Relationships Even though non-linear relationships are much more complicated than linear ones, they can be studied in their own right.

If you are studying these, you should first see if they fit any standard shapes like parabolas or exponential curves. These are commonly occurring relationships between variables. For example, the pressure and volume of nitrogen during an isentropic expansion are related as PV1.
Next, a number of non-linear relationships are monotonic in nature. This means they do not oscillate and steadily increase or decrease. This is good to study because they behave qualitatively like linear relationships for a number of cases.
In particular, a differential equation is linear if it is linear in terms of the unknown function and its derivatives, even if nonlinear in terms of the other variables appearing in it. As nonlinear dynamical equations are difficult to solve, nonlinear systems are commonly approximated by linear equations linearization. This works well up to some accuracy and some range for the input values, but some interesting phenomena such as solitonschaos and singularities are hidden by linearization.

It follows that some aspects of the dynamic behavior of a nonlinear system can appear to be counterintuitive, unpredictable or even chaotic. Although such chaotic behavior may resemble random behavior, it is in fact not random.
For example, some aspects of the weather are seen to be chaotic, where simple changes in one part of the system produce complex effects throughout.
This nonlinearity is one of the reasons why accurate long-term forecasts are impossible with current technology. Some authors use the term nonlinear science for the study of nonlinear systems. This is disputed by others: Using a term like nonlinear science is like referring to the bulk of zoology as the study of non -elephant animals.
