Class 9 Physics | Chapter 2 Kinematics | Numerical 2.8 | Velocity-Time Graph Problem | New Book 2025
In this lecture, we solve Numerical 2.8 from Chapter 2: Kinematics of Class 9 Physics according to the Punjab Textbook Board New Syllabus 2025.
This numerical is based on a Velocity-Time (v–t) Graph. Students are required to calculate distance travelled, acceleration, or displacement using graphical methods.
🔎 What You Will Learn:
How to read a Velocity-Time Graph
Finding acceleration from slope
Calculating distance from area under graph
Understanding uniform and non-uniform motion
Dividing graph into geometric shapes (triangle/rectangle)
Proper formula application in graph numericals
Step-by-step board exam presentation
📚 Important Concepts Covered:
✔ Slope = Acceleration
✔ Area under v–t graph = Distance/Displacement
✔ Uniform acceleration
✔ Graph interpretation skills
✔ Units and sign conventions
✔ Avoiding common graph mistakes
🎯 Why Numerical 2.8 Is Important:
Very important for Board Exams 2025
Frequently asked in MCQs & short questions
Builds strong understanding of motion graphs
Helps in solving real-life motion analysis problems
Strengthens full Chapter 2 preparation
