# AP Physics 2: Algebra-Based

Expand your understanding of physics as you explore topics such as fluids; thermodynamics; electric force, field, and potential; electric circuits; magnetism and electromagnetic induction; geometric and physical optics; and quantum, atomic, and nuclear physics. You’ll do hands-on and inquiry-based in-class activities and laboratory work to investigate phenomena. Note: Save your lab notebooks and reports; colleges may ask to see them before granting you credit.

### Skills You'll Learn

• Interpreting and describing representations and models

• Using mathematics to solve science problems

• Formulating a scientific question or hypothesis

• Designing an experiment to answer a scientific question or test a hypothesis

• Analyzing data and evaluating evidence

• Working with scientific explanations and theories

• Making connections

### Equivalency and Prerequisites

#### College Course Equivalent

A second-semester introductory college course in algebra-based physics.

#### Recommended Prerequisites

You should have completed AP Physics 1 or a comparable introductory physics course and should have taken or be concurrently taking pre-calculus or an equivalent course.
