After watching this lecture you feel psichologically prepared to accept the vector concept as able to represent some aspects of reality. Although the physicist needs mathematics as a tool, it is not be confused with Physics. Anyone can learn the rules of manipulating vectors, but seeing them "in action" is truly Physics. It is also made evident why describing vector quantities and comparing them to scalar quantities is the beginning of Physics studies. Later on, one realizes that are more complicated physical quantities, for which either scalars or vectors are not able to represent…
