Introduction
Gravitation and Hydrostatics form an important part of Class 10 Physics and are highly relevant for NDA and CDS examinations. These chapters explain the fundamental forces that govern natural phenomena, from the motion of planets to the behavior of liquids at rest. Understanding these concepts builds a strong base for solving numerical problems and conceptual questions commonly asked in competitive defence exams.
Gravitation deals with the universal force of attraction between masses. It helps us understand why objects fall towards the Earth, how planets revolve around the Sun, and how satellites stay in orbit. Concepts such as Newton’s Law of Gravitation, acceleration due to gravity (g), mass and weight, and pressure in solids and fluids are essential for both theoretical understanding and problem-solving.
Hydrostatics focuses on fluids at rest and explains how pressure behaves in liquids. Topics like pressure in liquids, Pascal’s Law, Archimedes’ Principle, buoyancy, and floatation are not only important for exams but also for real-life applications such as ships floating, submarines diving, and hydraulic machines working efficiently.
Together, these chapters strengthen analytical thinking and help aspirants apply physics principles to real-world and exam-based situations.
Importance for NDA CDS 1 2026 Exam
- Questions from Gravitation and Hydrostatics are frequently asked in the Physics section of NDA and CDS.
- Numerical problems based on formulas, units, and applications are common.
- Concepts like weight variation, pressure in liquids, and buoyant force are often tested.
- A clear understanding helps improve accuracy and speed, which are crucial for competitive exams.
- These topics also lay the foundation for higher-level physics in Class 11 & 12, useful for SSB and future training.
Conclusion
Gravitation and Hydrostatics are foundational chapters that connect physics theory with real-life applications and defence exam requirements. For NDA CDS 1 2026 aspirants, mastering these topics is essential to score well in the Physics section. A strong grasp of definitions, laws, derivations, and numerical problem-solving techniques will help candidates approach exam questions with confidence.
Consistent practice, conceptual clarity, and understanding the application of laws in daily life will not only help in clearing the written exam but also develop scientific reasoning required for a future officer in the Armed Forces. With focused preparation, these chapters can become a scoring area for success in NDA CDS 1 2026.
