## mass vector US English

A vector describing the position of a particle of matter, whose magnitude is the product of the mass of the particle and its distance from the origin.

## row vector US English

A vector represented by a matrix consisting of a single row of elements

## unit vector US English

## polar vector US English

A vector which changes sign when the signs of all its components are changed.

## Poynting vector US English

The vector product of the electric and magnetic field strengths at any point, which can often be interpreted as describing the magnitude and direction of the flow of electromagnetic energy.

## vector product US English

The product of two real vectors in three dimensions that is itself a vector at right angles to both the original vectors. Its magnitude is the product of the magnitudes of the original vectors and the sine of the angle between their directions
