Drawing Vector Diagrams
We can draw vectors in diagrams using arrows. The arrow has both:
- Size – the length of the arrow is related to the size of the vector. If there is a scale on the side saying that 1cm = 5m, then a 4cm vector line would be equal to 20m.
- Direction – if it’s a vector, don’t forget about direction. The direction of the arrow is very important. For example, you might have two arrows which are equal in length, but point in opposite directions, as in Fig 3.
