Lesson details
Key learning points
- Vectors can be multiplied by a scalar.
- Vectors cannot be multiplied by each other.
- Multiplication by a scalar can be done when the vectors are in column form.
- Multiplication by a scalar can be done when the vectors are drawn.
Keywords
Scalar - A scalar is a quantity that has magnitude but not direction.
Displacement - Displacement is the distance from the starting point when measured in a straight line.
Common misconception
A reflection of a vector in the x or y axis is not the reverse of a vector. This is often seen with equilateral triangles and vectors.
When multiplying the vectors by -1 this gives the opposite direction of the vector only. The magnitude remains the same. Investigate with pupils by drawing column vectors and multiply by -1 and compare.
