Vectors And The Dot Product
This animation introduces vectors as arrows with magnitude and direction, showing how they combine through addition and scaling. It then builds the dot product step by step, illustrating both the algebraic formula using components and the geometric meaning involving the angle between two vectors. Viewers see how the dot product measures alignment, why it becomes zero for perpendicular vectors, and how it connects to projections. Useful for students learning vector algebra in physics or introductory linear algebra courses.
