Description:

Module 2, Topic D opens with a formal definition of a vector. The arithmetical work for vector addition, subtraction, scalar multiplication, and vector magnitude is explored along with the geometrical frameworks for these operations. Students solve problems involving velocity and other quantities that can be represented by vectors. Parametric equations are introduced allowing students to connect their prior work with functions to vectors.

Title: PhET: Vector Addition
URL: https://phet.colorado.edu/en/simulation/vector-addition
Description:

In this PhET activity, students will explore vectors in 1D or 2D, and discover how vectors add together. Students will specify vectors in Cartesian or polar coordinates, and see the magnitude, angle, and components of each vector. Students will experiment with vector equations and compare vector sums and differences. This activity could be used to help teach a lesson on probability. This PheET activity can be downloaded and assigned to Google Classroom.
