  • Vector Addition: This HTML 5 applet helps learners to explore addition of vectors.  Enter two vectors and see the resultant vector.  Vectors are mathematical quantities used to represent concepts such as force or velocity which have both a magnitude and a direction.  The applet can also be used for subtraction, as the subtraction of vectors A - B may be changed into an addition A + (- B).
  • Vector Addition and Scalar Multiplication: Explanation, examples, and HTML 5 applet.
  • Vector Subtraction: This HTML 5 applet helps learners to explore subtraction of vectors.
  • Magnitude and direction of a vector calculator: The is a Java applet.  Enter the components of vector v as real numbers and press "enter".  The magnitude || v || and direction in degrees are displayed.  This is a good tool to also help learners check their work.
  • Dot product of two vectors calculator: The is a Java applet.  Enter the components of the two vectors as real numbers and press "Dot*".  The answer appears as a scalar.  Learners can also get an explanation of the dot product and see examples.

Academo.org: 3D Vector Plotter.  Enter two vectors of the form (x, y, z) and see the sum, difference, and cross-product of the vectors.  Clicking on the end of a vector will reveal its components.  You can rotate the diagram and zoom in and out.  When z=0, the interactive is useful for viewing vectors in 2D.  Aligns with VM-B.4.
