6.2 Dot Product of Vectors

What you’ll learn about The Dot Product Angle Between Vectors Projecting One Vector onto Another Work … and why Vectors are used extensively in mathematics and science applications such as determining the net effect of several forces acting on an object and computing the work done by a force acting on an object.

Dot Product

Properties of the Dot Product Let u, v, and w be vectors and let c be a scalar. 1. u·v = v·u 2. u·u = |u|2 3. 0·u = 0 4. u·(v + w) = u·v + u·w (u + v) ·w = u·w + v·w 5. (cu)·v = u·(cv) = c(u·v)
