Introduction to Vectors — Interactive Lesson (Ages 14–16)

What makes a vector different from a scalar? This 26-slide interactive introduction to vectors starts from the basics with magnitude and direction.

An Introduction to Vectors for Year 10–11 Maths

Students learn that a vector has both magnitude and direction, and how to write vectors in bold letters, as column vectors and as AB. They recognise equal vectors, find the magnitude using Pythagoras’ theorem, so that the vector (3, 5) has magnitude √34 = 5.83, and find negative vectors. They calculate a vector between two points, meet zero and unit vectors, and write a column vector using i and j.
