PP+ Force Vector Addition 1.5

The Addition of Force Vectors lab is designed to facilitate the exploration of vector addition of forces utilizing a force table. This lab is part of the Polyhedron Physics Plus suite, which comprises 24 educational iPad applications intended for classroom use. An opportunity to experience this technology firsthand is available through the complimentary PP+ Newton’s 2nd Law lab. Additionally, for those who wish to create their own experiments, the PP Force Table app provides a comparable apparatus devoid of predefined lab procedures and supplementary materials.

Each laboratory module features a sophisticated 3D simulation that yields realistic experimental data. Accompanying each lab are various educational resources, including introductory videos, theoretical background, detailed experimental procedures, analysis and reporting tools, a pre-lab quiz, post-lab questions, and teacher support materials. The simulated experimental data reflect both random and systematic errors, enabling students to apply standard data analysis and error analysis techniques in their findings, thereby simulating the experience of working with physical laboratory equipment.

These virtual labs can effectively replace hands-on experiments when access to traditional equipment is limited or serve as valuable supplements to conventional labs. They are particularly beneficial for students engaged in distance learning or homeschooling environments. Formative and summative evaluations indicate that there is no statistically significant difference in learning outcomes between students utilizing virtual labs and those participating in hands-on experiments. Preliminary data also suggest that students experiencing virtual labs as supplementary tools may demonstrate enhanced learning.

Polyhedron Physics was developed by Polyhedron Learning Media, Inc., with partial funding from the Institute of Education Sciences within the U.S. Department of Education under contract numbers ED-07-CO-0040 and ED-IES-11-C-0029, through the Small Business Innovation Research (SBIR) program.
