| Abstract | Despite the routine treatment it receives today, the parallelogram of forces was the subject of ontroversy, especially during the 19th century. The controversy concerned the reason why forces compose vectorially. If the parallelogram law is explained statically, then the parallelogram law transcends the laws of dynamics. Alternatively, if the parallelogram law is explained dynamically, then it becomes merely a corollary to Newton's second law. I examine the three most important rival approaches to explaining the parallelogram law and identify their principal strengths, weaknesses, and consequences. The dispute among these approaches ultimately turns on whether the parallelogram law would still have held, if forces had not been governed by Newton's second law. © 2011 American Association of Physics Teachers. |
