Scalar and vectors A scalar quantity is completely described with only a magnitude (a number). -Examples: mass, density, length, speed, time, temperature. A vector quantity has both a magnitude and a direction and obeys the parallelogram law of addition. -Examples: force, moment, velocity, acceleration.

Vector arithmetic If u , v , w are vectors in 2- or 3-space and k and l are scalar, then the following relationships hold: (a) u + v = v + u (b) u + 0 = 0 + u = u (c) k ( l u ) =( kl ) u (d) ( k + l ) u = k u + l u (e) ( u + v ) + w = u + ( v + w ) (f) u + (- u ) = 0 (g) k ( u + v ) = k u + k v (h) 1 u = u
