Simple Vector Addition Manipulative

Many of the variables in physics are vectors, and this is often the first class where students get to use vector addition to analyze a situation. This activity is a quick and easy way to introduce the concept of vector addition.

Materials Needed per pair of students:

set of cardstock vectors of different lengths
a piece of chalk

Step 1 Adding Vectors Graphically

Students should work in pairs for this activity. One student should randomly distribute the vectors on the desk in front of the pair of students, the second student is to align them to show graphical vector addition. (I demonstrate the different between translating a vector and rotating a vector when I explain this step with a large vector on the board.)
