# AP Physics 1

## AP Physics Program

AP Physics 1 is a full-year course that is the equivalent of a firstsemester introductory college course in algebra-based physics.

AP Physics 2 is a full-year course that is the equivalent of a secondsemester introductory college course in algebra-based physics. The course covers fluids; thermodynamics; electrical force, field, and potential; electric circuits; magnetism and electromagnetic induction; geometric and physical optics; and quantum, atomic, and nuclear physics.

## AP Physics 1 Course Overview

AP Physics 1 is an algebra-based, introductory college-level physics course. Students cultivate their understanding of physics through inquiry-based investigations as they explore these topics: kinematics; dynamics; circular motion and gravitation; energy; momentum; simple harmonic motion; torque and rotational motion; electric charge and electric force; DC circuits; and mechanical waves and sound.

### LABORATORY REQUIREMENT

This course requires that 25 percent of the instructional time will be spent in hands-on laboratory work, with an emphasis on inquirybased investigations that provide students with opportunities to demonstrate the foundational physics principles and apply the science practices.

Inquiry-based laboratory experiences support the AP Physics 1 course and AP Course Audit curricular requirements by providing opportunities for students to engage in the seven science practices as they design plans for experiments, make predictions, collect and analyze data, apply mathematical routines, develop explanations, and communicate about their work.

Colleges may require students to present their laboratory materials from AP science courses before granting college credit for laboratory work, so students should be encouraged to retain their laboratory notebooks, reports, and other materials.

### AP Physics 1 Course Content

Students explore principles of Newtonian mechanics (including rotational motion); work, energy, and power; mechanical waves and sound; and introductory, simple circuits. The course is based on six big ideas, which encompass core scientific principles, theories, and processes that cut across traditional boundaries and provide a broad way of thinking about the physical world. The following are the big ideas:

• Objects and systems have properties such as mass and charge. Systems may have internal structure.

• Fields existing in space can be used to explain interactions.

• The interactions of an object with other objects can be described by forces.

• Interactions between systems can result in changes in those systems.

• Changes that occur as a result of interactions are constrained by conservation laws.

• 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.

### Science Practices

Students establish lines of evidence and use them to develop and refine testable explanations and predictions of natural phenomena. Focusing on these disciplinary practices enables teachers to use the principles of scientific inquiry to promote a more engaging and challenging experience for AP Physics students. Such practices require that students:

• Use representations and models to communicate scientific phenomena and solve scientific problems;

• Use mathematics appropriately;

• Engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course;

• Plan and implement data collection strategies in relation to a particular scientific question;

• Perform data analysis and evaluation of evidence;

• Work with scientific explanations and theories; and

• Connect and relate knowledge across various scales, concepts, and representations in and across domains.

## AP Physics 1 Exam Structure

**AP PHYSCIS 1 EXAM: 3 HOURS**

### Assessment Overview

Exam questions are based on learning objectives, which combine science practices with specific content. Students are assessed on their ability to:

• Provide both qualitative and quantitative explanations, reasoning, or justification of physical phenomena, grounded in physics principles and theories;

• Solve problems mathematically — including symbolically — but with less emphasis on only mathematical routines used for solutions;

• Interpret and develop conceptual models; and

• Transfer knowledge and analytical skills developed during laboratory experiences to design and describe experiments and analyze data and draw conclusions based on evidence.

Students will be allowed to use a four-function, scientific, or graphing calculator on the entire AP Physics 1 and AP Physics 2 Exams. Scientific or graphing calculators (including the approved graphing calculators listed at www.collegeboard.org/ap/calculators) cannot have any unapproved features or capabilities.
