Taking Measurements When the particle's position we are trying to measure is on one of the axis, the measurement is rather easy to do, it is just a matter of counting the units on the scale of the axis and we're done. And what about when we have a position which isn't on any of the axis? Like in the figure below.
In this case we have to imagine that the particle is on both axis. So in this case we would have that it is 2 units in the "x" axis and 2 units on the "y" axis. In order to find out the total distance we use the following equation, where d is the total distance from the center, x is the distance on the "x" axis and y is the distance on the "y" axis.
In the above example we can see that the measure would be 2 units in the "x" axis and the same in the "y" axis. So the total distance from the center would be 2,82, this is the Mathematical procedure:
