Kinematics Part 1 | Average Speed, Displacement, Velocity & Position‑Time Graphs - Physics 11

Take the quiz when ready after the lesson: https://1drv.ms/w/c/2713457aa143ce7f/... In this lesson from the MathSupport channel ‪@mathsupportnow‬ , we explore the foundations of kinematics by working through three progressively challenging motion problems. You’ll learn the difference between distance and displacement, how to calculate average speed vs average velocity, and how to interpret position‑time graphs using slope. We walk through clear examples involving running, direction changes, and graphical motion to build strong intuition for real‑world physics. What You’ll Learn in This Video: ✅ Average Speed • Speed is a scalar (no direction)  • Formula: total distance ÷ total time  • Converting km/h → m/s using dimensional analysis  • Example: 10 km in 1 hour → 2.78 m/s ✅ Displacement (Vector Quantity) • Displacement depends on direction  • Positive vs negative direction conventions  • Why returning to the starting point gives zero displacement  • Example: +5 km east and –5 km west → 0 km ✅ Average Velocity • Velocity is a vector (magnitude + direction)  • Formula: displacement ÷ time  • Why average velocity can be zero even when speed is not  • Example: 0 km displacement → 0 m/s ✅ Position‑Time Graphs • How to read motion from a graph  • Why slope = average velocity  • Interpreting positive, zero, and negative slopes  • Example intervals:   • AB: positive slope → +6.7 m/s   • BC: horizontal line → 0 m/s   • CD: negative slope → –10 m/s 00:00 – Introduction: Kinematics Part 1 00:28 – Scenario: Runner travels east and west 00:49 – Average speed formula 01:54 – Total distance and time 02:29 – Converting km/h to m/s 03:24 – Displacement explained (vector) 04:21 – Positive vs negative direction 05:45 – Total displacement = 0 km 06:11 – Average velocity formula 06:36 – Why average velocity = 0 m/s 07:26 – Position‑time graph introduction 08:01 – Interval AB: positive slope 09:33 – Interval BC: slope = 0 12:00 – Interval CD: negative slope 13:31 – Final interpretation of motion 14:09 – Reminder to check the quiz This video is ideal for: 🎯 Grade 8–12 Physics 🎯 Science 10 Kinematics 🎯 AP Physics 1 Foundations 🎯 Canadian, US, UK, NZ, AUST, BC Science Curriculum 🎯 Teachers, tutors, and parents who need clear motion examples 👍 Like if this helped you 🔔 Subscribe for more step‑by‑step physics tutorials 💬 Comment with your questions or requests for future videos 📤 Share this with classmates, teachers, or study groups Video lessons to review:    • Graphing Linear Relations FAST| Slope, Y‑I...      • Solving Formulas for Variables | Algebra &...   #Kinematics #AverageSpeed #AverageVelocity #Displacement #PositionTimeGraph #PhysicsBasics #Science10 #Mathsupport #MotionGraphs
