Identifying Vector Direction and Conventions

This video tutorial introduces vectors, explaining their representation and direction. It covers how vectors are depicted using arrows, with magnitude and direction, and discusses the use of protractors to measure vector direction. The video also explores different conventions for expressing vector direction, such as using cardinal directions and angles. Finally, it provides resources for further learning, including concept builders and apps.
