If I travel from A at 30 m/s for 10 minutes
do I reach B
What if I am a rocket?
Maps and vectors
On the Road lesson 3
Know that vectors have magnitude (size)
Add vectors (tip to tail)
We are going to study journeys.
A journey can be described as a distance
A distance in a certain direction is called
displacement and is a vector.
Vectors are quantities with both size
Table of distances
Bordeaux Calais Lyon Marseille Paris Brest
Lyon 426 612
Marseille 498 879 270
Paris 492 228 390 651
Brest 489 534 759 939 486
Distances in in km in straight lines between places
Getting information from
Can you see that Calais, Lyon and
Marseille are on a straight line (or close)
Can you use the data table to find
Use a compass and ruler
Break down journeys around Caloundra
into distances and displacements (try
golden beach to kings beach)
If we travel from Marseille to
Bordeaux how far have travelled
We are resolving the displacement
We are only looking at the
moving towards Calais.
The map is from near Mt Hotham Ski
Use the scale to work out the
displacement from AC and from
AD. Use ideas about vectors to work
out the displacement going from DC.
Use a diagram and Pythagoras

Draw on the ski lift and use it estimate
the amount of cable needed.
