vektorsuurus preferred
  • suurus, mis on määratletud skalaarsuuruse ja vektori korrutisega
  • quantity which can be represented by a vector multiplied by a scalar quantity
vektorsuurus preferred
Usage examples
  • Vektorsuurusteks on nt kiirus, jõud ja elektrivälja tugevus.
Good to know
  • Vektorsuurust määratlev vektor on tavaliselt ühikvektor tavalises kahe- või kolmemõõtmelises geomeetrilises ruumis. Vektorsuurust saab esitada orienteeritud joonesegmendina, mida iseloomustab selle toimimispunkt, suund ja väärtus, kus väärtusarv on mittenegatiivne arv, mis korrutatakse mõõtühikuga. Vektorsuurust võib pidada kas toimekohaga seotuks (lokaliseeritud või seotud vektor) või mis tahes punktina, mis toimib sellega paralleelsel sirgjoonel (libisev vektor) või millel on ruumis mis tahes toimimispunkt (vaba vektor).

Usage examples
  • Examples of vector quantities are: velocity, force, electric field strength.
Good to know
  • The vector defining a vector quantity is generally a unit vector in the usual two- or three-dimensional geometrical space. A vector quantity can then be represented as an oriented line segment characterized by its point of acting, its direction and its magnitude, where the magnitude is a non-negative number multiplied by a unit of measurement. A vector quantity may be considered either as attached to a point of acting (localized or bound vector), or as having any point of acting on a straight line parallel to it (sliding vector), or as having any point of acting in the space (free vector).
