## About the Course

## Course Coverage Update

Colleges agree that Units 8-10 can be removed from AP Physics 1 since they are covered in AP Physics 2; accordingly, Units 8-10 are no longer tested in AP Physics 1. As of 2021, AP Physics 1 Exams focus exclusively on content covered in Units 1-7.

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

## Course Content

###
**Unit 1: Kinematics**

You’ll be introduced to the study of motion.

Topics may include:

- Position, velocity, and acceleration
- Representations of motion

**On The Exam**

12%–18% of exam score

###
**Unit 2: Dynamics**

You’ll revisit the concepts you worked with in Unit 1 to explore force, which is the interaction of an object with another object.

Topics may include:

- Systems
- The gravitational field
- Contact forces
- Newton’s First Law
- Newton’s Third Law and free-body diagrams
- Newton’s Second Law
- Applications of Newton’s Second Law

**On The Exam**

16%–20% of exam score

###
**Unit 3: Circular Motion and Gravitation**

You’ll build on your understanding of motion and force as you study more complex models of motion, such as the circular path of a satellite orbiting a planet.

Topics may include:

- Vector fields
- Fundamental forces
- Gravitational and electric forces
- Gravitational field/acceleration due to gravity on different planets
- Inertial vs. gravitational mass
- Centripetal acceleration vs. centripetal force
- Free-body diagrams for objects in uniform circular motion

**On The Exam**

6%–8% of exam score

###
**Unit 4: Energy**

You’ll learn the definitions of and relationships between energy, work, and power.

Topics may include:

- Open and closed systems: Energy
- Work and mechanical energy
- Conservation of energy, the work–energy principle, and power

**On The Exam**

20%–28% of exam score

###
**Unit 5: Momentum**

You’ll explore the relationship between force, time, and momentum and learn to use the law of conservation of momentum to analyze physical situations.

Topics may include:

- Momentum and impulse
- Representations of changes in momentum
- Open and closed systems: momentum
- Conservation of linear momentum

**On The Exam**

12%–18% of exam score

###
**Unit 6: Simple Harmonic Motion**

You’ll use the tools, techniques, and models you’ve learned in previous units to analyze a new type of motion: simple harmonic motion.

Topics may include:

- Period of simple harmonic oscillators
- Energy of a simple harmonic oscillator

**On The Exam**

4%–6% of exam score

###
**Unit 7: Torque and Rotational Motion**

You’ll explore the motion of an object rotating around an axis and you’ll study torque, the measure of a force that can cause rotational motion.

Topics may include:

- Rotational kinematics
- Torque and angular acceleration
- Angular momentum and torque
- Conservation of angular momentum

**On The Exam**

12%–18% of exam score
