The Addition of Force Vectors lab uses a force table to investigate the vector addition of forces. It is part of Polyhedron Physics Plus, a set of 24 iPad apps for use in the classroom. To see how they work, try the FREE PP+ Newton’s 2nd Law lab. For those who’d prefer to develop their own experiments, the PP Force Table app features a similar apparatus without lab procedures and other supporting materials. In addition to a 3D simulation that produces realistic data, each lab includes introductory videos, background theory, experimental procedure, analysis and reporting tools, pre-lab quiz, post-lab questions, and teacher support materials. The experimental data produced by the simulations are realistic, including random and systematic errors. These features allow students to use standard data analysis and error analysis techniques to report on their own unique data, just as if the experiment had been performed using hands-on equipment. These labs can serve as replacements for hands-on labs, especially when equipment is not available, or as supplements to hands-on labs. They are also a suitable option for students in distance learning and home school situations. Formative and summative evaluations showed no significant difference in learning between students using the virtual labs and those using hands-on labs. Preliminary results suggest increased learning by students using the virtual labs as supplements to hands-on. Polyhedron Physics was developed by Polyhedron Learning Media, Inc. with partial funding provided under contract numbers ED-07-CO-0040 and ED-IES-11-C-0029 from the Institute of Education Sciences in the U.S. Department of Education through the Small Business Innovation Research (SBIR) program. ## Key features - 3D force table simulation - Realistic experimental data with errors - Introductory videos and background theory - Analysis and reporting tools - Pre-lab quiz and post-lab questions - Teacher support materials ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/pp-plus-force-vector-addition/id622367226/reviews.md ### 4/5 — It's Ok *2014-09-11, version 1.1* It would be nice if it checked your calculations for accuracy and suggested correct values if the the forces aren't balanced. ### 3/5 — Has potential *2013-04-12, version 1.0* The app. Crashes. I would love to see it displaying the summation of weight A and B somewhere or displaying the weight or angle needed to be balanced.... ## Frequently asked questions about PP+ Force Vector Addition ### What is PP+ Force Vector Addition?
