Question from moumita, a student:

what differences take place to a vector because of choice of orientation of the coordinate axes and why??


A vector can be described by its magnitude and direction and neither of these are changed by a orientation change in the coordinate axes. The representation of the vector in terms of the coordinate axes does however change if there is a change in the coordinate axes. If for example positive and negative are reversed on the the y-axes then the y-component of the vector will change sign.

I hope this helps,
