Question 2: Discuss methods of vector representation.
Vector representation means how a vector quantity like force, displacement or momentum is represented on a paper. Vectors are represented by graphic or symbolic methods depending on the situation at hand.
(1) Graphical representation of vectors
Graphically, a vector is represented by a line having an arrow head at one end. The arrow head indicates the direction of the vector and the length of the line the magnitude of the vector.
For example, a force of 100 N directed north is represented as
(2) Symbolic representation
According to this method, a vector is represented either by a bold face English alphabet or an alphabet with an arrow-head on it.
