Move by a vector
The vector (3, 2) means move 3 right and 2 up.
If you start at (1, 4), you end at (4, 6).
Vectors
Quantities with size and direction.
A vector tells you how far and in what direction to move. It can represent a journey, a force, a velocity or a displacement.
Why it matters
Vectors help describe movement, forces, transformations, geometry and coordinates.
Things to watch for
- Confusing a point with a movement.
- Ignoring direction.
- Adding only lengths rather than combining components.
