Systems may have internal structure. Big Idea 2: Fields existing in space can be used to explain interactions. 11 Big Ideas Big Idea 3: The interactions of an object with other objects can be described by forces. Big Idea 4: Interactions between systems can result in changes in those systems. 12 Big Ideas Big Idea 5: Changes that occur as a result of interactions are constrained by conservation laws. Big Idea 6: Waves can transfer energy and momentum from one location to another without the permanent transfer of mass and serve as a mathematical model for the description of other phenomena. 13 Big Ideas Big Idea 7: The mathematics of probability can be used to describe the behavior of complex systems and to interpret the behavior of quantum mechanical systems. – Big Idea 7 applies to Physics 2 only 14 Big Ideas Concept Chart DIRECTIONS Working in groups of three, create a concept map that showcases the major concepts/topics of your assigned Big Idea(s). 15 ENDURING UNDERSTANDINGS AND ESSENTIAL KNOWLEDGE 16 Enduring Understandings BIG IDEA 3 The interactions of an object with other objects can be described by forces. Enduring Understanding 3.A: All forces share certain common characteristics when considered by observers in inertial reference frames. Enduring Understanding 3.B: Classically, the acceleration of an object interacting with other objects can be predicted by using . Enduring Understanding 3.C: At the macroscopic level, forces can be categorized as either long-range (action-at-a-distance) forces or contact forces. Enduring Understanding 3.D: A force exerted on an object can change the momentum of the object. Enduring Understanding 3.E: A force exerted on an object can change the kinetic energy of the object. Enduring Understanding 3.F: A force exerted on an object can cause a torque on that object. 17 Essential Knowlege BIG IDEA 3 The interactions of an object with other objects can be described by forces. Enduring Understanding 3.A: All forces share certain common characteristics when considered by observers in inertial reference frames. Essential Knowledge 3.A.3: A force exerted on an object is always due to the interaction of that object with another object. a. An object cannot exert a force on itself. b. Even though an object is at rest, there may be forces exerted on that object by other objects. c. The acceleration of an object, but not necessarily its velocity, is always in the direction of the net force exerted on the object by other objects. 18 Major Topics in Physics 1 and Physics 2 AP Course AP Physics 1 Introductory Algebra-Based Physics Course With a Focus on: kinematics; Newton’s laws of motion; torque; rotation motion and angular momentum; gravitation and circular motion; work, energy and power; linear momentum; oscillations, mechanical waves and sound; introduction to electric circuits AP Physics 2 Introductory Algebra-Based Physics Course With a Focus on: fluid statics and dynamics; thermodynamics with kinetic theory, PV diagrams and probability; electrostatics; electric circuits with capacitors; magnetic fields; electromagnetism; physical and geometric options; topics in modern physics 19 Major Topics in Physics 1 and Physics 2 • The Curriculum Framework aligns the major topics of the course under 7 Big Ideas • Teachers can design the course based on their own topic sequence • The table on pages 22–24 show how the topics are divided between AP® Physics 1 and AP Physics 2 ‹#› Course Sequence: Physics 1 and Physics 2 DIRECTIONS Work with a partner to: 1. Create a sequential list of the major topics you will cover in your course. 2. Match each of the topics to the Enduring Understandings and Essential Knowledge that they cover. 21 AP Physics 1 example TOPIC Enduring Understanding Impulse and Momentum 3.D A force exerted on an object can change 3.D.1 The change in momentum of an object is a vector in the direction of the the momentum of the object 4.B Interactions with other objects or systems can change the total linear momentum of a system. Conservation of momentum 5.D The linear momentum of a system is conserved. 22 Essential Knowledge net force exerted on the object. 3.D.2 The change in momentum of an object occurs over a time interval. 4.B.1 The change in linear momentum for a constant–mass system is the product of the mass of the system and the change in velocity of the center of mass. 4.B.2 The change in linear momentum of the system is given by the product of the average force on that system and the time interval during which the force is exerted. 5.D.1 In a collision between objects, linear momentum is conserved. In an elastic collision, kinetic energy is the same before and after. 5.D.2 In a collision between objects, linear momentum is conserved. In an inelastic collision, kinetic energy is not the same before and after the collision. 5.D.3 The velocity of the center of mass of the system cannot be changed by an interaction within the system. AP Physics 2 example TOPIC Enduring Understanding Essential Knowledge Static Fluids 1.E Materials have many macroscopic properties that result from the arrangement and interactions of the atoms and molecules that make up the material. 1.E.1 Matter has a property called density. 3.C At the macroscopic level, forces can be categorized as either long-range (action-ata-distance) forces or contact forces. 3.C.4 Contact forces result from the interaction of one object touching another object and they arise from interatomic electric forces. These forces include buoyant force. 5.B The energy of a system is conserved. 5.B.10 Bernoulli’s equation describes the conservation of energy in fluid flow. 5.F Classically, the mass of a system is conserved. 5.F.1 The continuity equation describes conservation of mass flow rate in fluids. Examples should include volume rate of flow, mass flow rate.
