Physics Explained Through a Video Game

This textbook explains algebra-based high school leveled mechanical physics through Bonk.io, a multiplayer physics browser game that runs on the Box2D physics engine. Materials from this video game are used to explain real-world physics concepts.

Note that the Table of Contents is subject to change and may not reflect recent structural changes.

Known existing issues:

¹ These topics were created before adopting an improved article structure. As such, these topics have fewer resources, such as not having end-of-section practice problems.

² For this topic, the Example 4 contains a mistake with the FBD of the koi fish and lily pad after collision. They should be treated as a single system for the problem. Also, editing likely needs to be done for clarity and accuracy with the remainder of the example.

³ For this section, there are relatively few in-depth examples, especially given the large scope of the topic. Also, the discussion of work as a scalar value probably can be simplified.

For this textbook, it is recommended that you have taken at least one year each of high-school leveled algebra and geometry.
