Let's solve some problems to better understand the behavior of forces that act on objects, and their effects on motion. In the process, we will clear some common misconceptions.

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 …

Learn how to use force diagrams to analyze the forces and torques acting on a rigid system. Explore how force and torque can lead to rolling in different situations.

Welcome to AP®︎/College Physics 2! In AP Physics 2, you'll learn about thermodynamics, electricity and magnetism, light, and modern physics. To make sure you’re prepared with the …

Practice choosing the correct free-body diagram for an object.

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 …
