Welcome back to Honours Physics! This is Lecture 4 as we continue our deep dive into Kinematics in 2-D. Today, we're tackling the essential and frequently tested topic of Circular Motion! 🎯 This video is crucial for students preparing for AP Physics 1 and 2 (2026) or any course covering mechanics. We break down the concepts to ensure you understand both the basics and the advanced physics behind objects moving in a circle. What You Will Learn in This Lecture: 1️⃣ Fundamentals of Circular Motion: Defining angular displacement, angular velocity , and angular acceleration . 2️⃣ Uniform Circular Motion (UCM): Detailed analysis of centripetal acceleration and its vector nature. 3️⃣ Non-Uniform Circular Motion: Understanding when both tangential acceleration (a_t) and centripetal acceleration are present, and how to find the net acceleration. 4️⃣ Problem-Solving: Applying the formulas to solve typical exam-style questions.
