In this lesson Chad covers displacement, velocity, and acceleration in two dimensions. The lesson serves as an introduction to motion in two dimensions (i.e. kinematics in 2d). He works out a problem involving 2d velocity and calculates the resulting 2d displacement. He then shows that the same 2d displacement could have been calculated by calculating first using the x-component of the velocity to calculate the x-component of the displacement and using the y-component of the velocity to calculate the y-component of the displacement, and then using the pythagorean theorem to calculate the 2d displacement. In so doing Chad demonstrates that the motion of an object in the x-direction and the motion in the y-dimension can be viewed and treated independently preparing students for projectile motion in the next lesson.
