04_What is a vector

Welcome to the next episode in our Vector Analysis series! In this video, we introduce one of the most important concepts in mathematics and physics: the vector. Understanding what a vector is is essential for describing physical quantities that have both magnitude and direction, such as displacement, velocity, force, and electric fields. In this lesson, we explain the meaning of vectors, how they differ from scalar quantities, and how vectors are represented graphically and mathematically. This video provides the foundation needed to analyze motion, forces, fields, and many advanced topics including vector calculus, electromagnetism, fluid dynamics, and plasma physics.
