Description AP Physics 2: Algebra Based is a course designed for the students who have successfully completed Honors Physics or AP Physics 1, and want to take the Physics 2: AlgebraBased Advanced Placement Test. As a continuation of the AP Physics 1: Algebra-Based coursework, AP Physics 2 goes beyond Newtonian mechanics and explores a more diverse set of physical phenomenon, including fluid mechanics, thermodynamics, electricity and magnetism, optics, and atomic and nuclear physics. These topics are dictated by the College Board’s Advanced Placement Program. Although calculus is not a prerequisite, it is recommended that it at least be taken alongside this course. Students must be very strong in mathematical-reasoning. Lab activities are an integral part of the course. They, too, are scholastically demanding and require the student to have a serious commitment toward the work. Summer assignments are required. The interpretation of data requires a level of thought and understanding not generally found in high school students. II. Objectives A.

Unit 1 Overview Content Area: Science Unit Title: Thermodynamics Target Course/Grade Level: Advanced Placement Physics 2: Algebra-Based Unit Summary: Thermodynamics is the study of work, energy, and heat. Thermodynamics deals with large-scale observations of whole systems. The study of thermodynamics gives physicists and students the tools necessary to analyze and simplify extremely complex systems involving vast numbers of interacting molecules. The principles applied in the study of thermodynamics will give students a better understanding of the energy dynamics involved in thermal expansion, heat transfer, refrigeration, and combustion engines. In this unit, students will be given a framework for representing the microscopic world of atoms and molecules in a very tangible, relatable context. This framework serves as an excellent jumping point for understanding other areas of physics involved in the microscopic, especially those of electricity and magnetism that are explored in depth later in this course. Primary interdisciplinary connections: Experimental data gathering, analysis and graphing using digital tools and computer software programs. Computer-based lab simulations and modeling of key scientific principles, laws and theories. Mathematical formulations and relationships to analyze data and draw conclusions. st 21 century themes: Scientific investigations and technological developments on new materials, devices and processes used in various areas of society such as, consumer products, health care, communications, agriculture and industry, transport and entertainment. Unit Rationale: Thermodynamics bridges such familiar concepts in physics as work and energy, and applies them to large systems with microscopic parts. By understanding how microscopic objects can act as a single system with macroscopic effects, students will be well-prepared for modeling charge as the basis for electrical systems. Learning Targets Standards 5.1 Science Practices: All students will understand that science is both a body of knowledge and an evidence-based, model-building enterprise that continually extends, refines, and revises knowledge. The four Science Practices strands encompass the knowledge and reasoning skills that students must acquire to be proficient in science. 5.3.A Properties of Matter: All objects and substances in the natural world are composed of matter. Matter has two fundamental properties: matter takes up space, and matter has inertia. Content Statements Mathematical, physical, and computational tools are used to search for and explain core scientific concepts and principles. Interpretation and manipulation of evidence-based models are used to build and critique arguments/explanations. Revisions of predictions and explanations are based on systematic observations, accurate measurements, and structured data/evidence. Mathematical tools and technology are used to gather, analyze, and communicate results. Empirical evidence is used to construct and defend arguments. Scientific reasoning is used to evaluate and interpret data patterns and scientific conclusions. Refinement of understandings, explanations, and models occurs as new evidence is incorporated. Data and refined models are used to revise predictions and explanations. Science is a practice in which an established body of knowledge is continually revised, refined, and extended as new evidence emerges. Science involves practicing productive social interactions with peers, such as partner talk, whole- group discussions, and small-group work. Science involves using language, both oral and written, as a tool for making thinking public. Ensure that instruments and specimens are properly cared for and that animals, when used, are treated humanely, responsibly, and ethically. CPI # Cumulative Progress Indicator (CPI) 5.1.12.A.1 Refine interrelationships among concepts and patterns of evidence found in different central scientific explanations. Develop and use mathematical, physical, and computational tools to build evidence-based models and to pose theories. Use scientific principles and theories to build and refine standards for data collection, posing controls, and presenting evidence. Design investigations, collect evidence, analyze data, and evaluate evidence to determine measures of central tendencies, causal/correlational relationships, and anomalous data. Build, refine, and represent evidence-based models using mathematical, physical, and computational tools. Revise predictions and explanations using evidence, and connect explanations/arguments to established scientific knowledge, models, and theories. Develop quality controls to examine data sets and to examine evidence as a means of generating and reviewing explanations. Reflect on and revise understandings as new evidence emerges. Use data representations and new models to revise predictions and explanations. Consider alternative theories to interpret and evaluate evidence-based arguments. Engage in multiple forms of discussion in order to process, make sense of, and learn from others’ ideas, observations, and experiences. Represent ideas using literal representations, such as graphs, tables, journals, concept maps, and diagrams. Electrons, protons, and neutrons are parts of the atom and have measurable properties, including mass and, in the case of protons and electrons, charge. The nuclei of atoms are composed of protons and neutrons. A kind of force that is only evident at nuclear distances holds the particles of the nucleus together against the electrical repulsion between the protons. Differences in the physical properties of solids, liquids, and gases are explained by the ways in which the atoms, ions, or molecules of the substances are arranged, and by the strength of the forces of attraction between the atoms, ions, or molecules. Heating increases the energy of the atoms composing elements and the molecules or ions composing compounds. As the kinetic energy of the atoms, molecules, or ions increases, the temperature of the matter increases. Heating a pure solid increases the vibrational energy of its atoms, molecules, or ions. When the vibrational energy of the molecules of a pure substance becomes great enough, the solid melts. 5.1.12.A.2 5.1.12.A.3 5.1.12.B.1 5.1.12.B.2 5.1.12.B.3 5.1.12.B.4 5.1.12.C.1 5.1.12.C.2 5.1.12.C.3 5.1.12.D.1 5.1.12.D.2 5.2.12.A.1 5.2.12.A.2 5.2.12.C.1 Unit Essential Questions How do we know thermal energy is transferred or exchanged?

The electric force is very much like the gravitational force that students are so familiar with, and yet the due to strength of the force and nature of electrons, the particles on which the electric force commonly acts upon, the electrical force produces very different effects on the physical world. Students will expand their notions of forces and develop new ideas of force fields as they learn about the electric force. These concepts will give students a basis for understanding static electricity, sparks and lightning, and electrical circuits, and provide students with a framework for understanding other fundamental forces in unit 7. Primary interdisciplinary connections: Experimental data gathering, analysis and graphing using digital tools and computer software programs. Computer-based lab simulations and modeling of key scientific principles, laws and theories. Mathematical formulations and relationships to analyze data and draw conclusions. 21st century themes: Scientific investigations and technological developments on new materials, devices and processes used in various areas of society such as, consumer products, health care, communications, agriculture and industry, transport and entertainment. Unit Rationale: Harnessing the power of the electric force has been the defining achievement of humanity in the last century. From illuminating our world, to global communication systems, to computers, thousands of unique pieces of technology depend on the electrical force, field, and potential. This unit provides students an important basis for understanding the backbone of their society, and provides basic principles that guide their study of electrical circuits, magnetism, and optics.

Science involves using language, both oral and written, as a tool for making thinking public. Some forces act by touching, while other forces can act without touching. Magnetic, electrical, and gravitational forces can act at a distance. The motion of an object changes only when a net force is applied. The magnitude of acceleration of an object depends directly on the strength of the net force, and inversely on the mass of the object. This relationship (a=Fnet/m) is independent of the nature of the force.

Science involves practicing productive social interactions with peers, such as partner talk, wholegroup discussions, and small-group work. Science involves using language, both oral and written, as a tool for making thinking public. Some forces act by touching, while other forces can act without touching. Magnetic, electrical, and gravitational forces can act at a distance. Batteries supply energy to produce light, sound, or heat. Electrical circuits require a complete loop through conducting materials in which an electrical current can pass. The flow of current in an electric circuit depends upon the components of the circuit and their arrangement, such as in series or parallel. Electricity flowing through an electrical circuit produces magnetic effects in the wires. When energy is transferred from one system to another, the quantity of energy before transfer equals the quantity of energy after transfer. As an object falls, its potential energy decreases as its speed, and consequently its kinetic energy, increases. While an object is falling, some of the object’s kinetic energy is transferred to the medium through which it falls, setting the medium into motion and heating it.

The laws governing this world were entirely unlike anything previously studied. The quantization of energy levels, observed in the photoelectric effect, revealed truths about the structure of atoms. Probabilistic models of particle motion and momentum, revealed by further research into quantum mechanics show how individual particles behave as mathematical functions. Einstein’s Theories of General Relativity and Special Relativity revealed even more about the interconnected nature of space, gravity, matter, and energy. The effects of these studies are far reaching, and have applications in astronomy, GPS systems, and nuclear power. The implications of modern physics provoke many of our deepest sci-fi fantasies, such as teleportation, black holes, warp-speed, and alternate universes. Primary interdisciplinary connections: Experimental data gathering, analysis and graphing using digital tools and computer software programs. Computer-based lab simulations and modeling of key scientific principles, laws and theories. Mathematical formulations and relationships to analyze data and draw conclusions. 21st century themes: Scientific investigations and technological developments on new materials, devices and processes used in various areas of society such as, consumer products, health care, communications, agriculture and industry, transport and entertainment. Unit Rationale: Quantum, atomic, and nuclear physics reveal a deeper insight into the structure of our universe. Though many would consider these studies abstruse, these fields reveal a greater simplicity in the universe, in the context of unification, than Newtonian mechanics can provide. Students should be exposed to these studies, as they serve as a starting point for probing the nature of matter and energy, both in our own sun and in radioactive/nuclear technologies used around the globe. Learning Targets Standards 5.1 Science Practices: All students will understand that science is both a body of knowledge and an evidence-based, model-building enterprise that continually extends, refines, and revises knowledge. The four Science Practices strands encompass the knowledge and reasoning skills that students must acquire to be proficient in science. 5.2.D Energy Transfer: The conservation of energy can be demonstrated by keeping track of familiar forms of energy as they are transferred from one object to another. Content Statements Mathematical, physical, and computational tools are used to search for and explain core scientific concepts and principles. Interpretation and manipulation of evidence-based models are used to build and critique arguments/explanations. Revisions of predictions and explanations are based on systematic observations, accurate measurements, and structured data/evidence. Mathematical tools and technology are used to gather, analyze, and communicate results. Empirical evidence is used to construct and defend arguments. Scientific reasoning is used to evaluate and interpret data patterns and scientific conclusions. Refinement of understandings, explanations, and models occurs as new evidence is incorporated. Data and refined models are used to revise predictions and explanations. Science is a practice in which an established body of knowledge is continually revised, refined, and extended as new evidence emerges. Science involves practicing productive social interactions with peers, such as partner talk, wholegroup discussions, and small-group work. Science involves using language, both oral and written, as a tool for making thinking public. Some forces act by touching, while other forces can act without touching. Magnetic, electrical, and gravitational forces can act at a distance. Light travels in a straight line until it interacts with an object or material. Light can be absorbed, redirected, bounced back, or allowed to pass through. The path of reflected or refracted light can be predicted. Energy is transferred from place to place. Light energy can be thought of as traveling in rays. Thermal energy travels via conduction and convection.

The student is able to predict and explain, using representations and models, the ability or inability of waves to transfer energy around corners and behind obstacles in terms of the diffraction property of waves in situations involving various kinds of wave phenomena, including sound and light. The student is able to make claims using connections across concepts about the behavior of light as the wave travels from one medium into another, as some is transmitted, some is reflected, and some is absorbed. The student is able to make predictions about the locations of object and image relative to the location of a reflecting surface. The prediction should be based on the model of specular reflection with all angles measured relative to the normal to the surface. The student is able to describe models of light traveling across a boundary from one transparent material to another when the speed of propagation changes, causing a change in the path of the light ray at the boundary of the two media. The student is able to plan data collection strategies as well as perform data analysis and evaluation of the evidence for finding the relationship between the angle of incidence and the angle of refraction for light crossing boundaries from one transparent material to another (Snell’s law). The student is able to make claims and predictions about path changes for light traveling across a boundary from one transparent material to another at non-normal angles resulting from changes in the speed of propagation. The student is able to plan data collection strategies and perform data analysis and evaluation of evidence about the formation of images due to reflection of light from curved spherical mirrors. The student is able to use quantitative and qualitative representations and models to analyze situations and solve problems about image formation occurring due to the reflection of light from surfaces. The student is able to use quantitative and qualitative representations and models to analyze situations and solve problems about image formation occurring due to the refraction of light through thin lenses. The student is able to plan data collection strategies, perform data analysis and evaluation of evidence, and refine scientific questions about the formation of images due to refraction for thin lenses. The student is able to analyze data (or a visual representation) to identify patterns that indicate that a particular mechanical wave is polarized and construct an explanation of the fact that the wave must have a vibration perpendicular to the direction of energy propagation. The student is able to identify the strong force as the force that is responsible for holding the nucleus together. The student is able to analyze electric charge conservation for nuclear and elementary particle reactions and make predictions related to such reactions based upon conservation of charge. The student is able to predict electric charges on objects within a system by application of the principle of charge conservation within a system. The student is able to apply conservation of nucleon number and conservation of electric charge to make predictions about nuclear reactions and decays such as fission, fusion, alpha decay, beta decay, or gamma decay. The student is able to predict the number of radioactive nuclei remaining in a sample after a certain period of time, and also predict the missing species (alpha, beta, and gamma) in a radioactive decay. Construct representations of the energy-level structure of an electron in an atom and to relate this to the properties and scales of the systems being investigated. The student is able to make predictions about using the scale of the problem to determine at what regimes a particle or wave model is more appropriate. The student is able to support the photon model of radiant energy with evidence provided by the photoelectric effect. The student is able to select a model of radiant energy that is appropriate to the spatial or temporal scale of an interaction with matter. The student is able to construct or interpret representations of transitions between atomic energy states involving the emission and absorption of photons. [For questions addressing stimulated emission, students will not be expected to recall the details of the process, such as the fact that the emitted photons have the same frequency and phase as the incident photon; but given a representation of the process, students are expected to make inferences such as figuring out from energy conservation that since the atom loses energy in the process, the emitted photons taken together must carry more energy than the incident photon.] The student is able to articulate the reasons that the theory of conservation of mass was replaced by the theory of conservation of mass–energy. The student is able to apply mathematical routines to describe the relationship between mass and energy and apply this concept across domains of scale. The student is able to apply conservation of mass and conservation of energy concepts to a natural phenomenon and use the equation E = mc2 to make a related calculation. The student is able to explain why classical mechanics cannot describe all properties of objects by articulating the reasons that classical mechanics must be refined and an alternative explanation developed when classical particles display wave properties. The student is able to articulate the reasons that classical mechanics must be replaced by special relativity to describe the experimental results and theoretical predictions that show that the properties of space and time are not absolute. [Students will be expected to recognize situations in which nonrelativistic classical physics breaks down and to explain how relativity addresses that breakdown, but students will not be expected to know in which of two reference frames a given series of events corresponds to a greater or lesser time interval, or a greater or lesser spatial distance; they will just need to know that observers in the two reference frames can “disagree” about some time and distance intervals.] The student is able to describe emission or absorption spectra associated with electronic or nuclear transitions as transitions between allowed energy states of the atom in terms of the principle of energy conservation, including characterization of the frequency of radiation emitted or absorbed. The student is able to articulate the evidence supporting the claim that a wave model of matter is appropriate to explain the diffraction of matter interacting with a crystal, given conditions where a particle of matter has momentum corresponding to a de Broglie wavelength smaller than the separation between adjacent atoms in the crystal. The student is able to predict the dependence of major features of a diffraction pattern (e.g., spacing between interference maxima) based upon the particle speed and de Broglie wavelength of electrons in an electron beam interacting with a crystal. (de Broglie wavelength need not be given, so students may need to obtain it.) The student is able to use a graphical wave function representation of a particle to predict qualitatively the probability of finding a particle in a specific spatial region. The student is able to use a standing wave model in which an electron orbit circumference is an integer multiple of the de Broglie wavelength to give a qualitative explanation that accounts for the existence of specific allowed energy states of an electron in an atom.
