Vector Addition

How do I add vectors?

In this post, we represent the distance and displacement of objects moving on a horizontal plane using vector addition and resolution of the components of vectors, as a part of the Prelim Physics course under the module Kinematics and sub-part Motion on a Plane. To add vectors together, we use the “head to tail” method where we match each vector head to tail and then find the resultant vector from the start point to the end.

The following two videos give insight into how to add vectors together to calculate the resultant vector, using triangle and parallelogram rules.
