WebbA unit vector is simply a vector whose magnitude is equal to 1. Given any vector v we can define a unit vector as: n ^ v = v ‖ v ‖. Note that every vector can be written as the product of a scalar and unit vector. Three vector products are implemented in sympy.physics.vector: the dot product, the cross product, and the outer product. WebbTranscript. Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity. Created by Sal Khan.
