Drag two or more forces and watch their resultant appear by the parallelogram, triangle or polygon rule, with the magnitude and direction worked out live.

Split a force into two parts along any two directions, perpendicular or not, or into x and y parts from an angle or a slope, with every step shown on the drawing.

Find the resultant of two or more forces with the parallelogram law, the triangle rule and the laws of sines and cosines.

Split a force into components along any two given directions, and see why oblique components are not projections.
