📚 Smart Sciences with Sir Mudassir presents another easy and concept-based lecture from Class 9 Physics Chapter 1: Physical Quantities & Measurement. In this video, we explain: 🔧 Systematic Error – Errors that are consistent and occur due to defective instruments or procedures. 👤 Random/Human Error – Unpredictable mistakes due to observation, timing, or reaction errors. 🧪 Measuring Cylinder – Learn how to accurately measure liquid volume with proper eye-level technique. 🌊 Displacement Can Method – A practical way to measure the volume of irregular solids using water displacement. This video helps build strong experimental skills, perfect for lab work and board exam preparation. Ideal for students of Punjab Board 2025 (English Medium). 👉 Don’t forget to LIKE, SHARE, and SUBSCRIBE for more simple and smart Physics & Math videos!
