Class 09 Physics New Book Chapter 01 Lec.12 Physical Balance, Stopwatch, measuring Cylinder
Welcome to our Class 9 Physics series! In this video, we dive into the fascinating world of **Physical Balance** and **Stopwatch**, two essential tools in physics experiments. We’ll explore how a physical balance is used to measure mass accurately and how a stopwatch helps in tracking time with precision.
But that’s not all! We’ll also break down the **key difference between mass and weight**, a fundamental concept that often confuses students. You’ll learn:
- What is mass, and how is it measured?
- What is weight, and how does it differ from mass?
- Why does weight change on different planets, but mass remains constant?
This video is based on the **Class 9 Physics new book syllabus**, making it perfect for students preparing for exams or anyone curious about the basics of physics. Don’t forget to like, share, and subscribe for more educational content!
**Key Topics Covered:**
1. Physical Balance: How it works and its uses
2. Stopwatch: Importance in measuring time
3. Mass vs. Weight: Clear explanation with examples
4. Practical applications in everyday life
