PhET: Vector Addition

Subject Area

Mathematics

Grade(s)

9, 10, 11, 12

Overview

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.

    Vocabulary

    • End-to-end
    • Component-wise
    • Parallelogram Rule
    • Sum of Two Vectors
    • Additive Inverse
    • Vector Subtraction

    Knowledge

    Students know:
    • The aspects of end-to-end, componentwise, and the parallelogram rule involving vectors.
    • The additive inverse of a vector has the same magnitude but the opposite direction.

    Skills

    Students are able to:
    • Draw and find the diagonal of a parallelogram.
    • Represent vectors on an xy-plane.
    • Find the components of a vector given the direction and magnitude.
    • Find the additive inverse of a vector.

    Understanding

    Students understand that:
    • There are multiple ways to find the sum and difference of a pair of vectors.
    • The magnitude of the sum of two vectors will not be the same as the sum of the magnitudes unless the vectors are in the same direction.
    • The vector with the larger magnitude will have the greatest effect on the result.
