What are vector magnitude and direction? We are used to describing vectors in component form. For example, ( 3, 4) . We can plot vectors in the coordinate plane by drawing a directed line segment from the origin to the point that corresponds to the vector's components:

An online calculator to calculate the magnitude and direction of a vector from it components. Let v be a vector given in component form by. v = < v 1 , v 2 >. The magnitude || v || of vector v is given by. || v || = √ (v 1 2 + v 2 2 ) and the direction of vector v is angle θ in standard position such that. tan (θ) = v 2 / v 1 such that 0 ...
Magnitude and Direction of Vectors. Magnitude of a Vector. The magnitude of a vector P Q → is the distance between the initial point P and the end point Q . In symbols the magnitude of P Q → is written as | P Q → | .
Find a vector's components from its magnitude and direction. Direction angle is not given directly.

3 mar 2017 · Magnitude and Direction. In order to describe a vector, we use two quantities, its magnitude and direction. Magnitude. The magnitude of a vector is simply the number that describes how big (or small) the vector is. The number can be any positive number or zero. It can be a fraction or decimal number to any precision that you can measure.
Representing Vectors. Vector quantities are often represented by scaled vector diagrams. Vector diagrams depict a vector by use of an arrow drawn to scale in a specific direction. Vector diagrams were introduced and used in earlier units to depict the forces acting upon an object. Such diagrams are commonly called as free-body diagrams.
