Top Gravitation Questions and Answers for Boards and Competitive Exams
FAQs on Gravitation Important Questions: Exam Guide for JEE, NEET & CBSE
1. What are some basic questions of gravitation?
Basic questions of gravitation focus on core principles and formulas important for exams. They usually include:
- Definition of gravitation and its universal law
- Formula and units of gravitational force
- Difference between gravity and gravitation
- Applications like satellite motion and planetary orbits
- Calculation-based problems on mass, distance, force
2. What are the important topics in gravitation?
Important topics in gravitation for competitive and board exams include:
- Newton’s Law of Universal Gravitation: statement, formula, derivation
- Gravitational constant (G): definition, value, significance
- Acceleration due to gravity (g): factors affecting g
- Difference between gravity and gravitation
- Motion of planets and satellites: Kepler’s Laws
- Escape velocity and orbital velocity
- Numerical problems (force, mass, radius, altitude)
3. What is the essential question about gravity?
An essential question about gravity is understanding how and why objects attract each other with a force proportional to their masses and inversely proportional to the square of their distance, as described by Newton's Law of Universal Gravitation. This forms the foundation for:
- Explaining free fall and weight
- Predicting planetary and satellite motion
- Solving exam-oriented numerical problems
4. Which topics should I focus on in gravitation for CBSE board exams?
For CBSE board exams, focus on the following gravitation topics:
- Universal Law of Gravitation (derivation and applications)
- Difference between gravity and gravitation
- Acceleration due to gravity (g) and its variation with altitude, depth
- Mass and weight concepts
- Numerical questions on force, mass, distance
- Short answer and reasoning questions
5. What is the difference between gravity and gravitation?
Gravity is the attractive force exerted by the Earth (or any massive body) on objects near its surface, causing them to fall. Gravitation is the universal force of attraction between any two objects with mass, no matter where they are in the universe.
- Gravity: Specific to Earth (or planets)
- Gravitation: Universal force, applies everywhere
- Both follow Newton's Law of Universal Gravitation
6. Where can I download gravitation important questions PDF for Class 11?
You can easily find and download gravitation important questions PDF for Class 11 on leading educational websites and exam preparation platforms. These resources offer:
- Curated questions for CBSE, JEE, NEET standards
- Answers and stepwise solutions
- Topic-wise and chapter-wise question banks
- Downloadable and printable formats for quick revision
7. Are numerical questions on escape velocity common in exams?
Yes, numerical questions on escape velocity frequently appear in Physics exams such as JEE, NEET, and CBSE Boards. You should be able to:
- Use the escape velocity formula v = √(2GM/R)
- Solve for escape velocity of Earth, Moon, or other planets
- Apply values for G (gravitational constant) and planetary radii
- Explain the concept and its derivation for long answer questions
8. How do I approach assertion-reason questions in gravitation?
For assertion-reason questions in gravitation, first read both statements carefully. Then:
- Determine if each statement is true or false independently
- Check if the reason correctly explains the assertion
- Use textbook principles—like Newton’s Law and properties of gravity—to justify each
- Practice with previous years’ assertion-reason questions for better accuracy
9. What are some exam traps or common misconceptions in gravitation?
Common exam traps in gravitation include:
- Confusing mass and weight
- Using incorrect values for G or units
- Not applying the inverse-square law properly
- Ignoring altitude or depth changes in g
- Mixing up concepts of gravity and gravitation
10. How should I write long answers for derivations in gravitation?
To write effective long answers for gravitation derivations:
- Start with the statement of the law or principle (Newton’s Law of Gravitation)
- Clearly mention all assumptions and variables
- Derive step-by-step, using appropriate formulas and justifying each step
- Draw neat, labelled diagrams if required
- End with a boxed final answer or summary
11. Do schools and coaching classes use the same gravitation questions?
Schools and coaching classes often use similar gravitation questions because both reference standard textbooks, NCERT patterns, and previous year questions. However:
- Coaching centers may include more advanced or competitive exam-style questions
- CBSE schools focus on board-exam requirements
- Practicing from both can improve problem-solving skills and exam confidence
