Phase I
Organise and categorise existing physics knowledge based on relevant physics textbooks, papers, and recognised physics systems. We use AI to help us search for physics categories that may have been overlooked.
1. Newtonian mechanics
2. Kinematics
3. Statics and dynamics
4. Fluid mechanics
5. Continuum mechanics
6. Electromagnetism
7. Optics
8. Thermodynamics
9. Acoustics
10. Relativity and Quantum Mechanics
Phase II
Based on the videos collected, one author summarises and organises the preliminary classification results from the first phase. For example:
Delete categories not covered by the videos (such as relativity and quantum mechanics, acoustics).
Subdivide certain categories, such as fluid mechanics into liquid fluid mechanics, air fluid mechanics, etc.
Supplement and expand certain categories found in the actual videos, such as biomechanics.
1. Gravity
2. Collisions and Model Penetration
3. Mechanics - Acceleration
4. Biomechanics
5. Conservation of Angular Momentum
6. Fluid Mechanics
7. Medium Resistance Laws
8. Buoyancy Laws
9. Thermodynamics Laws
10. Pendulum Motion Laws
11. Aerodynamics
12. Optics
13. Elasticity laws
Phase III
Based on the videos collected from real-life scenarios, several authors and physics experts further discussed and analysed some boundary cases, and further subdivided or integrated certain categories. And we use AI and embedding models to retrieve similar prior examples to inform human decision-making on edge cases.
For example:
Gravity was subdivided into: weightlessness, anti-gravity, and gravity delay effect.
Videos where small-mass objects collide with large-mass objects and cause them to fly away were categorised under momentum and energy conservation and incorporated into a subcategory of Newtonian mechanics.
Mechanics-Acceleration Category Further subdivided into several subcategories of Newtonian mechanics based on scenarios, such as: Rapid rotation of humans or objects categorised under momentum and energy conservation,
Sudden appearance or disappearance categorised under conservation of mass and quantity of matter,
Objects suddenly turning or moving without external forces are categorised into two subcategories of Newton's first law of motion.
The laws of pendulum motion and medium resistance are also categorised into the subcategories of Newtonian mechanics: conservation of momentum and energy, and conservation of momentum and energy.
1. Gravity
1. Weightlessness (zero gravity state)
