# AP Physics 1: Algebra-Based

Learn about the foundational principles of physics as you explore Newtonian mechanics; work, energy, and power; mechanical waves and sound; and introductory, simple circuits. You’ll do hands-on 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 to test a hypothesis

• Analyzing data and evaluating evidence

• Working with scientific explanations and theories

• Making connections

### Equivalency and Prerequisites

#### College Course Equivalent

A first-semester introductory college course in algebra-based physics

#### Recommended Prerequisites
