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.
If you’ve mastered this content and want to explore physics at the next level, we recommend our AP Physics 1 and AP Physics 2 courses. Give us feedback on this 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.
In AP Physics 2, you'll learn about thermodynamics, electricity and magnetism, light, and modern physics. To make sure you’re prepared with the fundamentals, we recommend completing high school physics before diving into AP Physics 2.
Learn physics using videos, articles, and NGSS-aligned practice exercises. Explore the fundamentals of motion and forces, non-contact interactions, energy, and waves.
Forces arise from interactions between two objects or systems of objects. Use free body diagrams and motion models from Unit 1 to analyze the effects of forces on systems. Translate between different representations of forces and motion, and use models to analyze how interactions cause change. Practice deriving equations from fundamental principles and use proportional reasoning to make ...
