Physical quantities and measurement techniques — practice question

State how a scalar quantity differs from a vector quantity.

State two examples for each type of quantity. scalar quantity 1 ........................................ 2 ........................................ vector quantity 1 ........................................ 2 ........................................

Fig. 1.1 shows the direction and size of two vectors P and Q. In the space next to Fig. 1.1, draw a labelled vector diagram to show the resultant vector obtained by adding vector P to vector Q. Draw vector P, vector Q and the resultant vector to the same scale as in Fig. 1.1.
