I have some questions on a paper that I am typing up, and I've looked through my text book and I cannot find this, or I just don't know where to look.
-Explain how to write a vector in terms of it's magnitude and direction.
You can describe a 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.
