Physics plays a vital role in developing scientific reasoning and analytical skills required for competitive examinations like NDA and CDS. Among the important topics of Class 10 Physics, Heat, Nuclear Fission, and Nuclear Fusion are highly relevant as they connect everyday phenomena with advanced scientific applications. These chapters strengthen conceptual clarity and form the foundation … Read more
Magnetism is a fundamental topic in Physics that deals with the properties and behavior of magnets and magnetic fields. It helps us understand how magnets attract or repel objects and how they are used in everyday life, such as in electric bells, compasses, motors, and generators. At the Class 8 level, magnetism builds a strong … Read more
Electrostatics and Electricity form the foundation of modern Physics and play an important role in understanding how electrical devices work in our daily lives. In Class 8 Physics, students are introduced to basic concepts such as electric charge, static electricity, conductors, insulators, electric current, voltage, and simple electric circuits. Electrostatics deals with charges at rest, … Read more
Gravitation and Hydrostatics are two fundamental topics of Physics that help us understand how forces act in nature and how fluids behave under rest. Gravitation explains the force of attraction between masses, which governs the motion of planets, satellites, falling objects, and even our weight on Earth. Hydrostatics deals with fluids at rest and helps … Read more
Introduction Motion is a fundamental concept in Physics, and one of its important types is Rotational Motion. Rotational motion refers to the motion of an object around a fixed point or axis. Unlike linear motion, where an object moves in a straight line, in rotational motion every point of the object moves in a circular … Read more
Work, Power, and Energy are fundamental concepts in Physics that help us understand how objects move and how forces act in our daily lives. From lifting a school bag to running, jumping, or even switching on a fan, these concepts explain how physical activities are performed. For NDA and CDS aspirants, building a strong foundation … Read more
Motion and Laws of Motion form the foundation of classical mechanics and are among the most scoring and frequently asked topics in the NDA and CDS examinations. Every physical phenomenon around us—whether it is the motion of a vehicle, flight of a projectile, recoil of a gun, or walking—can be explained using these basic principles. … Read more
Introduction Waves and Sound form an important and high-scoring portion of the Physics syllabus for NDA and CDS examinations. This topic explains how energy is transferred through oscillations and vibrations without the actual transfer of matter. In competitive exams like NDA–CDS, questions from this chapter are generally conceptual, formula-based, and application-oriented, making a strong conceptual … Read more
Introduction Light is one of the most important topics in Physics for NDA and CDS examinations because it directly connects basic physical principles with everyday phenomena. The chapters Reflection of Light, Refraction of Light, and Human Eye and the Colourful World together explain how light behaves when it strikes surfaces, passes through different media, and … Read more
Introduction Physics is the backbone of the NDA and CDS examinations, and Units and Dimensions form the foundation of the entire Physics syllabus. Every physical quantity—whether it is force, energy, pressure, or velocity—must be expressed correctly using appropriate units. Without a strong understanding of units and dimensions, solving numerical problems becomes error-prone and time-consuming. In … Read more
