MA19.PRE.13
Multiply a vector by a scalar.

Unpacked Content

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.
