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.

Learn Quantum Physics app is designed for students as well as research & teaching professionals. It almost all topics of Learn Quantum Physics are the clear and easy to understand. Quantum physics is the study of matter and energy at the most fundamental level. It aims to uncover the properties and behaviors of the very building blocks of nature. Learn Quantum Physics underlies how atoms work, and so why chemistry and biology work as they do. You me and the gatepost at some level at least, we’re all dancing to the quantum tune. If you want to explain how electrons move through a computer chip, how photons of light get turned to electrical current in a solar panel or amplify themselves in a laser, or even just how the sun keeps burning, you’ll need to use quantum physics. Quantum mechanics is a fundamental theory in Quantum Physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. Topics: - Introduction. - The Fundamental Interactions. - Applications Of Quantum Theory. - The Quantum of Action. - Quantum Imaging. - Grand Unification. - Quantum Mechanics. - Quantum Information Technology. - Quantum Lights and Solids. - The Fundamental Particles. - Interpreting Quantum Physics. - Alternate Interpretations. - The Completeness of Quantum Physics. - The Copenhagen Interpretation. - Matter Waves Matter. - Particle Spin. - Quantum Wave Mechanics. - Entanglement. - Light As A Wave. - Light As Particles. - The Principle Of Quantum Physics. - The Uncertainty Principle. - Wave Particle Duality. Learn Quantum mechanics is the body of scientific laws that describe the wacky behavior of photons, electrons and the other particles that make up the universe. Learn Quantum mechanics is the branch of physics relating to the very small. It results in what may appear to be some very strange conclusions about the physical world. What is Quantum Physics: Quantum Physics the branch of physics concerned with quantum theory. Physicists are exploring the potential of quantum science to transform our view of gravity and its connection to space and time. Quantum science may even reveal how everything in the universe (or in multiple universes) is connected to everything else through higher dimensions that our senses cannot comprehend.

Verdict
The clearest difference is review sentiment: PP+ Force Vector Addition at 50% against Learn Quantum Physics Pro's 0%. Learn Quantum Physics Pro's advantage is rating (4.5 vs 3.3) and ratings volume (24 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
PP+ Force Vector Addition costs $1.99 and Learn Quantum Physics Pro $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Learn Quantum Physics Pro holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: Learn Quantum Physics Pro has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of PP+ Force Vector Addition's written reviews are positive against 0% of Learn Quantum Physics Pro's, so the app with the better star average is not the one people write more warmly about.
PP+ Force Vector Addition ships an update every 16 months, Learn Quantum Physics Pro every 11 months. The most recent releases landed on September 23, 2026 and October 8, 2026 respectively.
