NCEA Physics | Forces, Newton’s Laws & Circular Motion | Free Body Diagrams | Year 11–12 NZ

This video is a comprehensive NCEA Physics Mechanics lesson for New Zealand students, focusing on forces, Newton’s laws of motion, circular motion, and free body diagrams. In this session, we address common difficulties students face in mock exams by building a clear understanding of how forces act, how net force causes acceleration, and how to apply these ideas to real exam-style problems. Topics covered in this lesson include: ✔ Newton’s First, Second, and Third Laws of Motion ✔ Net force and why Fnet = ma must be used in exams ✔ Weight as a force (Fg = mg) and normal reaction forces ✔ Balanced vs unbalanced forces ✔ Mechanical forces vs electrical forces ✔ Introduction to circular motion ✔ Centripetal acceleration and centripetal force (Fc = mv²/r) ✔ Real-world examples of circular motion (cars, satellites, washing machines) ✔ Why astronauts feel weightless in orbit ✔ Drawing and interpreting free body diagrams ✔ Free body diagrams for: – A box on a flat surface – A person in an accelerating elevator – An object on an inclined plane ✔ Resolving forces into components using sine and cosine This lesson helps students: • Understand forces conceptually, not just memorise formulas • Apply Newton’s laws correctly in NCEA exams • Draw accurate free body diagrams • Solve mechanics problems step by step • Build confidence with circular motion questions This video is suitable for: • Year 11 NCEA Physics students • Year 12 NCEA Physics students • Students preparing for Mechanics internals and externals • Learners struggling with forces and diagrams 📌 Like the video if it helps 📌 Subscribe to Ararise Academy for structured NCEA Maths & Physics lessons 📌 Comment if you want more worked Mechanics or FBD examples
