In real life, people often ask what is the magnitude; the answer is not that easy to give. In fact, most people have no idea what it is at all! For those who are interested in learning about this concept, a definition and explanation of this term will be given in this article.
In mathematics, size or magnitude of an object is a measurement property that determines whether or not the object is smaller or greater than other similar objects of the same type. More formally, the measurement of an object’s magnitude is simply the displayed result of a geometric ordering, of the sort that occurs when a set of units is plotted on a graph. The magnitude of an object can be evaluated by calculating its center of mass, its velocity, and its distance from any point on the graph. If all these variables are known, then the answer to what is the magnitude will be the distance between the center of mass and any point on the graph. Sometimes, however, a third variable must be specified in order to evaluate the magnitude of an object.
To define what is magnitude, it is necessary to describe the different measures that we use in measuring objects. First of all, when we speak of a force of gravity, we mean the pull of the earth upon an object. We also speak of forces at constant velocity, known as gravitational energy, and of potential energy, known as the potential energy of motion. Then there are the time measurements, such as the duration of time it takes for an object to move from one place to another. Finally, there are only measurable distances, such as those between points on the surface of the earth.
What is magnitude, then, has very little to do with these different types of measurement. It would be a difficult concept indeed, if not an oxymoron, to explain how the different types of measurements could be used to determine what is the magnitude. For example, if we were to measure the distance between two points on the surface of the earth using the gravitational force of gravity, we would find that the distance was definite, while the time element would have to be determined experimentally, and its value set by experimentation. And so, what is the magnitude would simply be an ambiguous term. It would describe the different relationships between different quantities, but not the quantity itself.
The relationship between what is the magnitude and the force that it represents is actually more straightforward. As already stated, the gravitational force is constant, while time and potential energy are variable. Thus, it is possible to determine what is the magnitude using either of them. Similarly, the force of gravity acting upon an object determines what is magnitude, as does the clockwise and counter-clockwise rotational movement of a clock. This relationship shows up explicitly in the equations of mechanics.
The question “what is the magnitude?” can also be answered by observing the laws of physics, which show that, given a reference frame, the position and orientation of any system can be described by a coordinate system which lies along a single axis. In this case, what is the magnitude then is the angle and distance between the system’s axis of rotation and the reference point. This is why we can measure objects in the real world using simple measurements like measuring the distance. To measure the rotational velocity of heavenly bodies, we use the solar system’s radius, while to measure the velocity of a particle in a laboratory, we make use of its motion with respect to its acceleration. The concept of what is magnitude then becomes clear.
Physicists define what is the magnitude as a certain value of a parameter that they define. They then take these values and average them over a period of time to form a new value of what is magnitude. The definition of a constant is that it cannot change, and the definition of a variable is that it varies according to some other outside influence. Thus, for instance, the value of x will always be the same no matter what is done to the reference frame. It is only when you take the average value of different terms, like the speed of light, that you start to see differences in what is measured.
Thus, the relationship between what is the magnitude and force is not as simple as many think. Force is indeed affected by distance, but not so much that we would know what is termed “force” by looking at the relationship between distance and time. We can say that the relationship is proportional, but then again the definition of what is magnitude also needs to be changed because if we take the average value of all the terms, then what we get is pretty much what we first said nobody can change anything unless they want to. Thus, one might conclude that force is only indirectly related to what is measured. But then again, what is the measurement can also be defined by what is called “the standard yardstick” by many philosophers.
