Introduction
Motion is one of the most fundamental topics in Physics and forms the foundation for understanding advanced concepts in Mechanics. In simple words, motion refers to the change in position of an object with respect to time and a chosen reference point. Every movement we observe in daily life—walking, running, flying aircraft, moving vehicles, or even the motion of celestial bodies—comes under the study of motion.
For students preparing for NDA & CDS 1 – 2026, this chapter is extremely important because it introduces basic terminology and concepts such as distance, displacement, speed, time, and types of motion, which are frequently used in higher-level Physics questions. A strong grasp of Motion at the Class 6 level ensures clarity and confidence while solving numerical problems in later classes.
Overview of the Chapter
In this chapter, students learn:
- What is motion and rest
- Types of motion such as rectilinear, circular, periodic, and oscillatory motion
- Difference between distance and displacement
- Concept of speed and its calculation
- Measurement of time and speed
- Simple real-life examples related to motion
The chapter emphasizes observation, understanding, and logical reasoning, which are essential skills for defence exams like NDA and CDS.
Importance for NDA & CDS 1 – 2026 Exam
For NDA & CDS 1 – 2026, Motion is a high-weightage base topic because:
- Questions often test basic concepts rather than complex formulas
- Many numerical problems in later chapters depend on motion fundamentals
- Understanding motion helps in problem-solving speed and accuracy
- Concepts of motion are linked to defence applications such as movement of troops, vehicles, aircraft, and missiles
Candidates with strong basics can easily handle questions related to speed–time relations and real-life motion scenarios, which are common in NDA examinations.
Conclusion
Motion is the first step into the world of Physics, making it a crucial chapter for every NDA & CDS aspirant. A clear understanding of motion helps students develop analytical thinking and prepares them for advanced topics in Mechanics. For NDA–CDS 1 (2026), mastering this chapter ensures a strong foundation, better conceptual clarity, and improved performance in the Physics section.
By focusing on definitions, examples, and basic numerical problems, students can score well and build the confidence required to succeed in competitive defence examinations.
