Hello Chinnie15I'm not sure that there is any particular way towritea vector in terms of its magnitude and direction.

You candescribea vector in terms of its magnitude and direction by giving several examples; for instance:

... and so on.

- The displacement vector of a point from a point can be written as and would be described in terms of the distance (in suitable units) and the angle that the line segment measured from a fixed direction. E.g. units in a direction making an angle of with the direction of the -axis.

- The velocity vector of a moving body can be described in terms of the speed of the body and the direction of its motion at a particular instant. E.g. a shell is fired in a north-easterly direction at m/sec at an angle of above the horizontal.
