NCEA Physics | Inclined Planes, Friction & Tension | Equilibrium Problems | Year 11–12 NZ

This video is an NCEA Physics Mechanics lesson for New Zealand students, focusing on forces on inclined planes, friction, tension, equilibrium, and circular motion through worked examples. In this session, we solve multiple exam-style problems step by step, using free body diagrams and trigonometry to calculate acceleration, net force, and tension correctly. Topics covered in this lesson include: ✔ Free body diagrams for objects on inclined planes ✔ Resolving weight into parallel and perpendicular components ✔ Calculating acceleration on a slope without friction ✔ Including friction and finding the new net force ✔ Understanding that net force is not always equal to weight ✔ Tension in hanging objects in equilibrium (T = mg) ✔ Applying Fnet = 0 for stationary systems ✔ Centripetal force for a car moving in a circular path ✔ Using Fc = mv² / r in circular motion problems ✔ Importance of remembering constants such as g and common squares ✔ Solving tightrope equilibrium problems using trigonometry ✔ Resolving forces into horizontal and vertical components ✔ Using sinθ and cosθ correctly in force balance equations This lesson helps students: • Draw accurate free body diagrams • Identify the correct net force in each situation • Apply Newton’s laws confidently • Use trigonometry effectively in Mechanics problems • Build exam confidence with multi-step questions This video is suitable for: • Year 11 NCEA Physics students • Year 12 NCEA Physics students • Students revising Mechanics and Forces • Learners struggling with friction, tension, or equilibrium 📌 Like the video if it helps 📌 Subscribe to Ararise Academy for structured NCEA Maths & Physics lessons 📌 Comment if you want more inclined plane or equilibrium examples
