This zip file contains two Geogebra files that dynamically illustrate vector concepts - one that shows the forces on an object on an inclined plane and one that shows the resultant of three forces acting at a point. Thanks to Greg Bland for sharing these. Both are excellent teaching aids - 3 thumbs up!

Geogebra is a fantastic FREE dynamic geometry program that can be downloaded from
