Magnitude of a 3d vector











But the quantities like speed, mass, distance, volume, temperature, etc. Quantities such as velocity, displacement, force, momentum, etc are the vector quantities. Now if we have to find the magnitude of a vector formula and we need to calculate the length of any given vector.

magnitude of a 3d vector

We can also subtract one vector from another, keeping the two points given below in our mind:įirstly, we need to reverse the direction of the vectors we want to subtract, this changes the sign of the vector from positive to negative.Īs we know, that vector can be defined as an object which has both magnitudes as well as it has a direction. Now, we can add two vectors by simply joining them head-to-tail, refer the diagram given below for better understanding:Īnd it doesn't matter in which order the two vectors are added, we get the same result anyway:Ī vector can often be written in bold, like a or b. The length of the line or the arrow given above shows its magnitude and the arrowhead points in the direction. In the following article, the magnitude and direction of vectors are explained.Ī vector has magnitude (that is the size) and direction: Understanding the magnitude of the vector would indicate the strength of the force and similarly, the speed of any object is associated with the velocity. Force and velocity are the two examples of vector quantities. A vector is an object that contains both a magnitude and a direction.
