​AP Physics 1 - Unit 2a Review - Newton's Laws and Forces
Good morning! Join us for an in-depth review of Unit 2: Forces and Translational Dynamics for AP Physics 1. We’ll cover Newton's Laws, including key details often missed, and explain how to calculate the center of mass for both systems of particles and objects with shape. Discover why force vectors only belong in free-body diagrams and learn how to handle forces on inclines. We’ll also discuss the differences between static and kinetic friction, the importance of breaking forces into components, and how to apply Newton’s Third Law in various scenarios.
