  • AP Physics 2

    AP Physics 2: Algebra-Based is a second-year physics course designed for high school students in grade 12 who have completed AP Physics 1.  The course covers topics and concepts typically included in the second semester of an algebra-based, introductory college-level physics course.  Topics include  fluid statics & fluid dynamics, thermal physics & thermodynamics, electricity & magnetism (including RC circuits and electromagnetic induction), light & optics, and modern (quantum, atomic & nuclear) physics.  The course focuses on high-level understanding of concepts, experimental design and critical thinking, and prepares students for the AP Physics 2 exam in May.

    Pressure & Fluid Mechanics

    Notes pp. 295-316

    Fluid mechanics is the study of behaviors that are specific to fluids (liquids and gases).

    • Pressure is the property that is central to the topic of fluid mechanics.

    Electricity & Magnetism

    Notes pp. 179-227

    This chapter discusses electricity and magnetism, how they behave, and how they relate to each other.

    • Electric Change, Coulomb’s Law, and Electric Fields describe the behavior of individual charged particles and how to calculate the effects of these particles on each other.
    • Electric Current & Ohm’s Law describes equations and calculations involving the flow of charged particles (electric current).

    Light & Optics

    Notes pp. 257-294

    This chapter discusses the behavior and our perception of light.

    • Electromagnetic Waves discusses properties and equations that are specific to electromagnetic waves (including light).
    • Color discusses properties of visible light and how we perceive it.
    • Reflection, Refraction, Polarization, and Diffraction discuss specific properties of light, and the equations that relate these properties.
    • Mirrors and Lenses discuss what happens when the direction of a ray of light is changed by a mirror or a lens.

    One of the new skills learned in this chapter is visualizing and drawing representations of how light is affected as it is reflected off a mirror or refracted by a lens.   This can be challenging because the behavior of the light rays and the size and location of the image changes depending on the location of the object relative to the focal point of the mirror or lens.  Another challenge is in drawing precise, to-scale ray tracing drawings such that you can use the drawings to accurately determine properties of the image, or of the mirror or lens.

    Skills learned & applied in this chapter:

    • Drawing images from mirrors and through lenses.

    Modern Physics

    Notes pp. 317-362

    This chapter discusses the particles that atoms and other matter are made of, how those particles interact, and the process by which radioactive decay can change the composition of a substance from one element into another.

    • The Bohr Model of the Hydrogen Atom describes the first attempts to use quantum mechanics to describe the behavior of the electrons in an atom.  The Quantum Mechanical Model of the Atom describes the evolution of atomic theory from the Bohr model to the present day.
    • Fundamental Forces describes the four natural forces that affect everything in the universe.  The strong nuclear force and the weak nuclear force are particularly relevant to this chapter.
    • The Standard Model and Particle Interactions describe properties of and interactions between the particles that all matter is made of.
    • Radioactive Decay, Nuclear Equations, Mass Defect & Binding Energy, Half-Life, and Nuclear Fission & Fusion describe and give equations for the nuclear changes that radioactive elements undergo.

    One of the challenging aspects of this chapter is that it describes process that happen on a scale that is much too small to observe directly.  Another challenge is the fact that the Standard Model continues to evolve.  Many of the connections between concepts that make other topics easier to understand have yet to be made in the realm of atomic & particle physics.
