A vector is defined by a direction, an orientation and a norm and is represented by an arrow.

Use this animation to introduce the notion of vector. Trace up to three vectors in the cartesian plane. Represent equal, opposite, or collinear vectors. View their components and establish relationships between them. Move the vectors, their components remain unchanged.

Two equal vectors are carried by parallel lines, their components are identical.

Two opposite vectors are carried by parallel lines, their components are opposite.
