Vocabulary
- Scalar Multiple
- Scalar Multiplication
- Scaling Vectors
Knowledge
Students know:
- The representation of vectors graphically on the xy-plane.
Skills
Students are able to:
- Find the components of a vector.
- Find the magnitude and direction of a vector.
Understanding
Students understand that:
- Scalar multiplication results in a dilation of the original vector where a scalar greater than 1 would increase the magnitude and a scalar from 0 to 1 would decrease the magnitude.
- A negative scalar would reverse the direction of the vector.
- The absolute value of the scalar has the resulting effect on the magnitude.
