Design Challenges & Solutions:

Challenge: Light taxonomy only contains 6 concepts, while Optics contains 30 concepts Solution: Combined Light and Optics into Chapter 11 (41 concepts total) as they form a natural thematic unit about electromagnetic radiation and its behavior

Challenge: Waves taxonomy (19 concepts) and Sound taxonomy (11 concepts) are closely related conceptually Solution: Combined into Chapter 10 (30 concepts) since sound is an application of wave principles, and this maintains pedagogical flow

Challenge: Foundation concepts (19) need to appear first but shouldn't be split Solution: Dedicated Chapter 1 with all foundational concepts, establishing mathematical and scientific literacy before physics-specific topics

Challenge: Kinematics concepts can be split into 1D and 2D motion Solution: Separated into Chapters 2 and 3, allowing students to master linear motion before tackling vector decomposition in projectile motion

Challenge: Dynamics concepts (24 total) would create an oversized chapter Solution: Split into Chapter 4 (conceptual foundations of Newton's Laws) and Chapter 5 (applications and problem-solving), maintaining 11-13 concepts each

Challenge: Ensuring all 200 concepts have dependencies satisfied Solution: Validated all edges in the learning graph - no concept appears before its prerequisites across all chapters

Statistics:

  • Total chapters: 12
  • Average concepts per chapter: 16.7
  • Range: 6-41 concepts per chapter
  • All 200 concepts covered: ✓
  • All dependencies respected: ✓

# Forces and Newton's Laws ## Summary This chapter introduces the fundamental principles of dynamics by exploring the relationship between forces and motion. You'll learn Isaac Newton's three laws of motion, which form the cornerstone of classical mechanics. Starting with the concept of force as a vector quantity, you'll discover how net force determines acceleration, why objects resist changes in motion through inertia, and how action-reaction pairs arise in all interactions. The concepts of equilibrium—both static and dynamic—will help you understand when objects remain at rest or move with constant velocity despite experiencing multiple forces. ## Concepts Covered This chapter covers the following 13 concepts from the learning graph: … +25 lines (ctrl+o to expand)

# Work, Energy, and Power ## Summary This chapter introduces one of physics' most powerful concepts: energy and its conservation. You'll learn how forces do work to transfer energy, and how energy transforms between kinetic energy (energy of motion) and potential energy (stored energy). The work-energy theorem provides an alternative approach to solving mechanics problems, often simpler than using Newton's laws directly. You'll distinguish between conservative and non-conservative forces, analyze energy transformations using diagrams, and explore power as the rate of energy transfer. Simple machines demonstrate how mechanical advantage can amplify forces, though energy conservation always applies. These energy principles will reappear throughout the rest of physics. ## Concepts Covered This chapter covers the following 15 concepts from the learning graph:

# Momentum and Collisions ## Summary This chapter introduces momentum, a vector quantity that describes the "quantity of motion" an object possesses. You'll discover how impulse (force applied over time) changes momentum, and learn one of physics' most important principles: conservation of momentum in isolated systems. This conservation law enables you to analyze collisions—elastic collisions where kinetic energy is conserved, and inelastic collisions where it is not. You'll solve collision problems in both one and two dimensions, understand how the center of mass moves for systems of objects, and explore rocket propulsion as a dramatic application of momentum conservation through Newton's third law. ## Concepts Covered This chapter covers the following 10 concepts from the learning graph: … +24 lines (ctrl+o to expand)

# Rotational Motion and Angular Momentum ## Summary This chapter extends the concepts of linear mechanics to rotational motion, revealing beautiful parallels between translational and rotational quantities. Angular displacement, velocity, and acceleration describe rotational kinematics, while torque (the rotational analog of force) causes angular acceleration. You'll discover that an object's resistance to rotational acceleration depends on its rotational inertia, which varies with mass distribution. Rotational kinetic energy and angular momentum complete the rotational analogs of linear mechanics. The conservation of angular momentum explains phenomena from spinning figure skaters to orbiting planets, and rolling motion combines both translational and rotational motion in a single framework. ## Concepts Covered This chapter covers the following 10 concepts from the learning graph: … +25 lines (ctrl+o to expand)

# Oscillations and Periodic Motion ## Summary This chapter explores periodic motion, where objects repeat the same motion pattern over time. Simple harmonic motion (SHM) is the most fundamental type of oscillation, characterized by a restoring force proportional to displacement. You'll analyze SHM using amplitude, period, frequency, and angular frequency, and study two classic oscillating systems: springs obeying Hooke's Law and pendulums swinging under gravity. Real oscillations experience damping due to non-conservative forces like friction and air resistance. When external forces drive oscillations at specific frequencies, resonance can occur with dramatic effects—from shattering wine glasses to destroying bridges. These principles apply throughout physics and engineering. ## Concepts Covered This chapter covers the following 14 concepts from the learning graph: … +29 lines (ctrl+o to expand)

# Waves and Sound ## Summary This chapter explores mechanical waves—disturbances that propagate through a medium, transferring energy without transferring matter. You'll distinguish between transverse waves (where particles oscillate perpendicular to wave motion) and longitudinal waves (where particles oscillate parallel to wave motion), and characterize waves using wavelength, frequency, period, and wave speed. Wave interference creates constructive and destructive patterns explained by the superposition principle, and reflection leads to standing waves with nodes and antinodes. Waves also exhibit refraction (bending when changing media) and diffraction (spreading around obstacles). The Doppler effect describes frequency shifts for moving sources or observers. Sound waves exemplify all these principles, with additional properties including intensity measured in decibels, pitch related to frequency, and phenomena like beats, harmonics, and acoustic resonance that shape the music and sounds around us. ## Concepts Covered This chapter covers the following 30 concepts from the learning graph: … +45 lines (ctrl+o to expand)

# Light and Optics ## Summary This chapter explores light as an electromagnetic wave and examines how it interacts with matter. You'll study the electromagnetic spectrum from radio waves to gamma rays, focusing on the visible spectrum humans can perceive. Light's reflection follows precise laws that govern mirrors—from simple plane mirrors to curved spherical mirrors (concave and convex) analyzed using mirror equations and ray diagrams. Refraction occurs when light changes media, described by Snell's Law and the index of refraction, and leads to total internal reflection at critical angles. Lenses (convex and concave) refract light to form real and virtual images, analyzed using lens equations, thin lens formulas, and ray diagrams with focal lengths. Dispersion separates white light into colors through prisms, explaining rainbows and related phenomena. Color addition and subtraction describe how we perceive color. Light also exhibits wave properties through optical diffraction in Young's double slit experiment, single slit diffraction, and diffraction gratings. Finally, polarization demonstrates light's transverse wave nature. This comprehensive treatment reveals light's dual nature and practical applications in optics. ## Concepts Covered This chapter covers the following 41 concepts from the learning graph:

# Electric Charge and Electric Fields ## Summary This chapter introduces electrostatics, the study of electric charges at rest and the forces they exert. You'll discover that charge comes in two types—positive and negative—and is conserved in all processes. Materials are classified as conductors, insulators, semiconductors, or superconductors based on how easily charge flows through them. Charge can be transferred through friction, contact, or induction, and grounding provides a path for excess charge to dissipate. Coulomb's Law quantifies the electric force between charges, analogous to Newton's law of gravitation. This force can be visualized using the electric field concept, represented by electric field lines and characterized by field strength. Moving charges in electric fields involves electric potential energy, which leads to the concepts of electric potential and voltage—the energy per unit charge. These foundational concepts in electricity underlie all electronic technology and prepare you for deeper study of circuits and electromagnetism. ## Concepts Covered This chapter covers the following 20 concepts from the learning graph: … +33 lines (ctrl+o to expand)
