Using the Parallelogram Rule to Find Net Force in Two Dimensions

Watch the video at the left to learn how to use the Parallelogram Rule and a simulation to add vectors in two dimensions, and then try your hand with the Vector Addition Simulation below. Note: You don't really need the simulation to add vectors in two dimensions; you can use the Parallelogram Rule to add vectors on your own sheet of paper. The simulation, however, is a nice tool to help you learn the Parallelogram Rule.
