vectors

• In mechanics: Vectors

  …a quantity that has both magnitude and direction. It is typically represented symbolically by an arrow in the proper direction, whose length is proportional to the magnitude of the vector. Although a vector has magnitude and direction, it does not have position. A vector is not altered if it is…

  …joining q1 to q2, with magnitude 1/r2 as required by the inverse square law. When r is rendered in lightface, it means simply the magnitude of the vector r, without direction. The combination 4πε0 is a constant whose value is irrelevant to the present discussion. The combination q1r/4πε0r3 is called…
