## Table of Contents

- 1. Units and Problem Solving
Students explore and understand the importance of units, which identify what a specific number represents. Examples of types of measurements, commonly used symbols, fundamental units, and unit conversions are given in this chapter.

- 2. Energy Conservation
Students are introduced to energy conservation and the conservation laws that govern our universe. Physicists have identified five conservation laws, which are discussed in this chapter.

- 3. One-Dimensional Motion
This chapter covers one-dimensional motion, velocity, acceleration, and deceleration.

- 4. Two-Dimensional and Projectile Motion
This chapter discusses parabolic and projectile motion, acceleration, and velocity.

- 5. Newton's Laws
Students learn about Newton's Law's through the study of motion, acceleration, and force.

- 6. Centripetal Forces
Centripetal force is introduced through the study of force, velocity changes, net-forces, applied forces, and acceleration.

- 7. Momentum Conservation
This chapter introduces momentum conservation through the study of motion, mass, velocity, force of gravity, and collision.

- 8. Energy and Force
The law of conservation of energy and the law of conservation of momentum is introduced through the study of energy and force.

- 9. Rotational Motion
The third conservation law is conservation of angular momentum. Conservation of angular momentum is explored through the concepts of rotational velocity, rotational inertia, angular momentum, torque, linear, and rotational motion.

Simple harmonic motion (SHM) concepts are presented in this chapter through the study of periodic motion, oscillation, restorative force, frequency, amplitude, and kinetic energy.

- 11. Wave Motion and Sound
Wave motion and sound is presented through harmonic motion, longitudinal and transverse waves, constructive and destructive interference, sound and water waves.

Students are introduced to electricity through the study of the conservation of charge. Other concepts such as electromagnetism, the Coulomb electric force, the law of gravity, charged objects, electric force, and potential energy are presented.

- 13. Electric Circuits: Batteries and Resistors
Electric circuits - batteries and resistors are presented through the study of Ohm's Law, electric currents, electric fields, voltage, current, resistance, AC and DC power.

- 14. Magnetism
Magnetism is studied through the concepts of electromagnetic force, the Coulomb electric force, electric current, magnetic fields, electricity, the right and left hand rules.

- 15. Electric Circuits: Capacitors
Students learn about electric circuits - capacitors through the study of electric potential, electrical charge, dielectric constants, and capacitance.

- 16. Electric Circuits: Advanced Topics
Students study advanced topics in electric circuits through the study of modern circuitry including diodes, inductors, transistors, operational amplifiers, and other chips.

- 17. Light
Light is studied through the concepts of light waves, electromagnetic radiation and fields, electrons, photons, Fermat’s Principle, refraction, diffraction, scattering and color absorption, and dispersion.

- 18. Fluids
We study fluids and apply the concepts of force, momentum, and energy. The concept of conservation of energy density in place of conservation of energy is presented as well as Archimedes’ Principle, Pascal’s Principle, Bernoulli’s Principle.

- 19. Thermodynamics and Heat Engines
Thermodynamics and heat engine concepts are presented through the study of heat, molecular kinetic energy, energy transfer, laws of thermodynamics, temperature of a gas, Adiabatic process, entropy, and the first and second laws of thermodynamics.

Particle physics is introduced through the concepts of matter, particles, subatomic particles, the Standard Model, CPT symmetry, fermions, bosons, leptons, quarks, and four fundamental forces in nature.

- 23. Feynman Diagrams
Feynman diagrams are used to calculate the probability of collisions, annihilations, or decays of particles. Drawing Feynman diagrams is the first step in visualizing and predicting the subatomic world.

- 24. Quantum Mechanics
This chapter introduces quantum mechanics, the description of how the universe works on the very small scale. The foundation of quantum mechanics was developed on the observation of wave-particle duality.
