I CAN DETERMINE THE CHANGE IN POSITION OVER TIME ALONG TWO AXIS.

Vectors and Scalars Vectors require a magnitude & a direction. – Example: Displacement is a vector. Scalars require only a magnitude. – Example: Distance is a scalar. Add to your CN about position, distance and displacement

Vector/Scalar example: Millie and Maxine start from their Paris apartment.

Vector/Scalar example: Millie and Maxine start from their Paris apartment. Maxine drives 3 miles west. Millie drives 3 miles.
