(a) (i) State the difference between a scalar quantity and a vector quantity.

(ii) State two examples of each type of quantity.

(b) 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.
