AP Physics 1 — Free Body Diagrams: Forces & Practice Problems
Learn how to draw free body diagrams and analyze forces in AP Physics 1. This video walks through contact forces, field forces, and step-by-step practice problems to help you understand force representation and problem-solving strategies for your AP exam. We'll break down the fundamentals of forces, explore how to properly draw FBDs with correct arrow notation, and apply these skills to real scenarios including stationary objects, angled pulls, ramps with friction, and tension systems. Great for reviewing Unit 1 and Unit 2 concepts. ⏱️ TIMESTAMPS: 0:00 Introduction to Free Body Diagrams 0:38 Stream Overview and Agenda 1:12 Defining Forces as Push or Pull 1:43 Units of Force and Newton 2:14 Contact vs Field Forces 2:47 Examples of Contact Forces 3:18 Field Forces like Gravity 3:49 Four Fundamental Forces 4:53 Electromagnetism Details 5:55 Focus on Key Forces 7:04 Representing Forces with Symbols 9:40 Rules for Drawing FBDs 10:59 Arrow Direction and Length 13:04 Stationary Box on Table 16:13 Pushed Box Not Moving 20:26 Pulling at an Angle 23:44 Trig Components for Angles 26:23 Box on Ramp with Friction 29:34 Breaking Gravity into Components 34:21 Practice Problems Start 35:24 Book at Rest on Tabletop 36:59 Falling Object Ignoring Air 39:38 Book Pushed with Acceleration 42:22 Constant Velocity Push 43:23 Car Coasting and Slowing 46:36 Suspended Object by Ropes 48:54 Motionless Object with Tensions 53:48 Final Practice Questions 56:08 Advanced FBD Scenarios 56:39 Stream Conclusion and Thanks 📝 WHAT YOU'LL LEARN: • How to identify contact forces vs field forces • Rules for drawing accurate free body diagrams • Breaking angled forces into components using trig • Analyzing objects on ramps with friction • Solving tension problems with multiple ropes • Practice problems for exam preparation 👍 Subscribe for more AP Physics 1 review sessions and study guides to strengthen your understanding throughout the year. 📚 STUDY AP PHYSICS 1 WITH FIVEABLE: Study guides, practice questions, and exam prep for AP Physics 1. 📖 Study Guides: https://fiveable.me/ap-physics-1 ✏️ Practice Questions: https://fiveable.me/guided-practice/a... #APPhysics1 #FreeBodyDiagrams #APExamPrep #PhysicsHelp #StudyWithMe
