Newton's Second Law: Grade 11 Physics Exam Question (Eastern Cape 2023) | iCampSA

Master Newton's Second Law of Motion with this step-by-step solution to Question 4 from the November 2023 Eastern Cape Physics Paper 1. This lesson covers connected blocks, friction, and inclined surfaces. Key concepts covered in this tutorial:Annotating the Problem: Identifying forces like normal force, tension, and kinetic friction [01:44]. Free Body Diagrams (FBD): Drawing accurate FBDs for both the 8kg and 4kg blocks, including resolving weight components on an incline [05:31]. Newton’s Second Law in Words: The formal definition required for exam marks [08:06]. Calculating Tension: Setting up simultaneous equations (Fnet = ma) for connected systems [11:37]. Resolving Force Components: Using trigonometry (sin and cos) for weight parallel and perpendicular on a slope [17:51]. Coefficient of Friction: Understanding why the coefficient of friction (mu_k) remains constant even when the incline angle changes [28:37]. This lesson is perfect for South African Grade 11 and 12 learners preparing for their Physics Paper 1 exams. #Grade11Physics #NewtonsLaws #PhysicsP1 #PhysicalScienceSA #Friction #InclinePlanes #iCampSA #ScienceExamPrep
