Student Book 
7th 1 Sketch of jet ski with up and down 
arrows, labelled upthrust and weight. 
Up and down arrows of equal size. 
5th 2 Mass measures the amount of material, 
weight is a force; mass is a scalar 
quantity, weight is a vector quantity; 
mass is measured in kilograms, weight is 
measured in newtons. 
7th 3 It is a distance in a particular direction. 
7th 4 Their displacement is zero, as they end up 
at the same point from which they started. 
7th 5 They are going around a bend, so their 
direction is changing. 
8th 6 The down arrow should be labelled 
'weight', as 1000 N is a measurement 
of force. The 'speed' label should read 
velocity, as a direction
