AP Physics 1

Last updated

Advanced Placement (AP) Physics 1: Algebra Based [1] (also known as AP Physics 1) is a year-long introductory physics course administered by the College Board as part of its Advanced Placement program. It is intended to proxy a one-semester algebra-based university course in mechanics. Along with AP Physics 2, the first AP Physics 1 exam was administered in 2015.

History

The heavily computational AP Physics B course served as the College Board's algebra-based offering for four decades. As part of the College Board's redesign of science courses, AP Physics B was discontinued; therefore, AP Physics 1 and 2 were created with guidance from the National Research Council and the National Science Foundation. [2] The course covers the material of a first-semester university undergraduate physics course offered at American universities that use best practices of physics pedagogy. [3] The first AP Physics 1 classes had begun in the 2014–2015 school year, with the first AP exams administered in May 2015.

In its first five years, AP Physics 1 covered forces and motion, conservation laws, waves, and electricity. [4] As of 2021, AP Physics 1 includes mechanics topics only. [5]

In February 2024, College Board announced that there would be changes in curricula for their AP Physics classes for the 2025 exams. For AP Physics 1, this added fluids to the list of topics covered on the exam, now the last unit of the curriculum. Previously, this topic was covered as the first unit of AP Physics 2. In the revised curriculum, fluids cover 10-15% of the AP Physics 1 exam. College Board made other minor changes to the curriculum, such as providing equations for simple harmonic motion, connections between rotational and translational motion, and learning objectives related to power. [6]

Curriculum

AP Physics 1 is an algebra-based, introductory college-level physics course that includes mechanics topics such as motion, fluids, force, momentum, energy, harmonic motion, and rotation. The College Board published a curriculum framework that includes eight big ideas on which AP Physics 1 is based. [7]

Questions for the exam are constructed with direct reference to items in the curriculum framework. Student understanding of each topic is tested regarding multiple skills—that is, questions require students to use quantitative, semi-quantitative, qualitative, and experimental reasoning in each content area.

UnitsExam Weighting
Kinematics 10-15%
Force and Translational Dynamics 18-23%
Work, Energy and Power 18-23%
Linear Momentum 10-15%
Torque and Rotational Dynamics 10-15%
Energy and Momentum of Rotating Systems 5-8%
Oscillations 5-8%
Fluids 10-15%

The content of AP Physics 1 overlaps significantly with that of AP Physics C: Mechanics. However, AP Physics 1 is algebra-based and lacks calculus-based concepts in AP Physics C: Mechanics. Another difference is that AP Physics C: Mechanics does not cover fluids, while AP Physics 1 does.

It is intended to serve as a proxy for a one-semester calculus-based university course in mechanics. Physics C: Mechanics may be combined with its electricity and magnetism counterpart to form a year-long course that prepares for both exams.

Advanced Placement (AP) Physics C: Electricity and Magnetism is an introductory physics course administered by the College Board as part of its Advanced Placement program.

Advanced Placement (AP) Latin, formerly Advanced Placement (AP) Latin: Vergil, is an examination in Latin literature offered to American high school students by the College Board's Advanced Placement Program. Prior to the 2012–2013 academic year, the course focused on poetry selections from the Aeneid, written by Augustan author Publius Vergilius Maro, also known as Vergil or Virgil. However, in the 2012–2013 year, the College Board changed the content of the course to include not only poetry, but also prose. The modified course consists of both selections from Vergil and selections from Commentaries on the Gallic War, written by prose author Gaius Julius Caesar. Also included in the new curriculum is an increased focus on sight reading. The student taking the exam will not necessarily have been exposed to the specific reading passage that appears on this portion of the exam. The College Board suggests that a curriculum include practice with sight reading. The exam is administered in May and is three hours long, consisting of a one-hour multiple-choice section and a two-hour free-response section.

There are four Advanced Placement (AP) Physics courses administered by the College Board as part of its Advanced Placement program: the algebra-based Physics 1 and Physics 2 and the calculus-based Physics C: Mechanics and Physics C: Electricity and Magnetism. All are intended to be at the college level. Each AP Physics course has an exam for which high-performing students may receive credit toward their college coursework.

AP Capstone, officially known as the Advanced Placement Capstone Diploma Program, is a 2-year program developed by the College Board that consists of two courses: the AP Seminar and AP Research.
