First year science students 6 chapter imp questions for physics 🌟🙀

Here are important questions (IMP questions) from Physics for First Year Science students (Class 11), based on common topics across various educational boards (like CBSE, State Boards, etc.). These are compiled chapter-wise for the first 6 chapters: --- 📘 Chapter 1: Physical World 1. What is Physics? Explain its scope and importance. 2. Differentiate between classical and modern physics. 3. Explain the role of Physics in technology and society. 4. Write short notes on: Fundamental forces in nature. Unification of forces. 5. Why is Physics considered a basic science? --- 📘 Chapter 2: Units and Measurements 1. Define fundamental and derived units with examples. 2. Explain the concept of significant figures with examples. 3. Explain the different types of errors and how to minimize them. 4. Write the rules for rounding off measurements. 5. State the SI base units and their symbols. 6. Derive the dimensions of: Force Energy Pressure --- 📘 Chapter 3: Motion in a Straight Line (Kinematics) 1. Define displacement, speed, velocity, and acceleration. 2. Derive the equations of motion for uniformly accelerated motion. 3. Draw and explain: Distance-time graph Velocity-time graph 4. Difference between average speed and instantaneous speed. 5. A numerical based on free fall or vertical motion. --- 📘 Chapter 4: Motion in a Plane 1. Differentiate between scalar and vector quantities. 2. Explain the method of vector addition (Parallelogram Law). 3. Derive the expression for the projectile motion: Time of flight Maximum height Range 4. Explain uniform circular motion with examples. 5. Solve numericals based on vector components and projectile motion. --- 📘 Chapter 5: Laws of Motion 1. State and explain Newton’s three laws of motion with examples. 2. What is inertia? Explain its types. 3. Derive the equation from Newton’s Second Law. 4. Explain the concept of: Action and reaction forces Friction and types of friction 5. Solve numerical problems based on: Force Friction Tension in strings --- 📘 Chapter 6: Work, Energy and Power 1. Define work. What are its units? When is work said to be: Positive Negative Zero 2. Derive the work-energy theorem. 3. Define kinetic and potential energy. Give expressions. 4. State and prove the law of conservation of energy. 5. Define power and commercial unit of energy. 6. Solve numerical problems on work, energy, and power. --- If you tell me your syllabus board (CBSE, Maharashtra Board, etc.), I can tailor the questions even more specifically. Let me know if you need the answers or numericals solved too. 🌟🔥 by study tools
