Pressure and Deformation in Solids | Class 9 Physics Chapter 5 | Conceptual and Short Questions | Question 1 to 10 | Important Questions | Federal Board | New Book NBF This video covers key conceptual and short-answer questions (Q1–Q10) from Class 9 Physics Chapter 5 (Pressure and Deformation in Solids) based on the FBISE/National Book Foundation syllabus. It aims to help students grasp concepts, apply formulas, and improve exam performance. 📝Today's lecture notes: https://drive.google.com/file/d/1XTlh... Questions Covered in This Video: Q1. While walking on a trampoline, do you feel more pressure when you stand still or jump up and down? Why does pressure change with movement? Q2. How does the shape of a thumb pin help it to penetrate surfaces easily? Q3. If you blow up a balloon and then tie it closed, why does it stay inflated even though you stop blowing? How does pressure play a role here? Q4. Why is an inner airtight layer of a spacesuit designed to maintain constant pressure around an astronaut? Q5. If a liquid has a density twice the density of mercury, what will be the height of the liquid column in a barometer? Q6. Why would we not be able to sip water with a straw on the Moon? Q7. How are we able to break a metal wire by bending it repeatedly? Q8. A spring has spring constant k when loaded with a mass m. If the spring is cut into two equal parts and one part is loaded with the same mass m, what will be its new spring constant? Q9. Why do static fluids always exert force perpendicular to the surface? Q10. How can a small car lifter lift a load heavier than itself? Complete Class 9 Physics Conceptual Questions (Ch 1–9): https://www.youtube.com/playlist?list...
