Let's think about what physics is and what topics are covered in an introductory physics course.
Physics is built on a foundation of math and it seeks to explain all phenomena in the universe. It forms the basis for other sciences like chemistry and biology. Physics uses simple yet elegant math to describe complex phenomena, from galaxies to biological systems. It's about understanding and predicting the universe's complexity based on simple ideas.
Welcome to AP®︎/College Physics 1! In AP Physics 1, you'll learn algebra-based classical mechanics. To make sure you’re prepared with the fundamentals, we recommend completing high school physics before diving into AP Physics 1.
Khan Academy offers free, world-class education in physics, covering forces and motion topics.
Complete AP Physics guide for US students. AP Physics 1 and AP Physics C units, notes, formula sheets, and practice problems to prepare for the 2026 AP exams.

From the structure of atoms to the properties of heat, light, and sound, we explain physics in plain English. Use up and down arrows to review and enter to select.
AP Physics 1 includes algebra-based foundations of mechanics and fluids, taught through eight units: kinematics; forces and translational dynamics; work, energy, and power; linear momentum; torque and rotational dynamics; energy and momentum of rotating systems; oscillations; and fluids.
This introductory, algebra-based, two-semester college physics book is grounded with real-world examples, illustrations, and explanations to help students grasp key, fundamental physics concepts.
The Physics Classroom Tutorial presents physics concepts and principles in an easy-to-understand language. Conceptual ideas develop logically and sequentially, ultimately leading into the mathematics of the topics.
