System of Particles – 1 | NEET Physics 2026 Live | A to Z Series | DNA Learning

Описание: Welcome to DNA Learning’s NEET Physics LIVE class on System of Particles – Part 1.
This lecture is part of the A–Z NEET Physics Series, specially structured for NEET 2026 aspirants who aim to build strong conceptual foundations and score maximum marks in Physics. The chapter System of Particles is one of the most important topics in Mechanics and acts as a bridge between Laws of Motion, Work–Energy, and Rotational Motion.

In this Part 1 session, we focus on Centre of Mass (COM), motion of a system of particles, and fundamental concepts that are frequently tested in NEET through direct, indirect, and application-based questions.

If you truly want to understand Physics rather than memorise formulas, this class is a must-watch.

🌟 Why “System of Particles” Is Extremely Important for NEET

Every year, NEET asks multiple questions directly or indirectly from this chapter. Concepts of centre of mass are used in:

Collision problems

Rocket motion

Circular and rotational motion

Rigid body dynamics

Momentum conservation

Explosions and separation problems

Students who skip or weakly understand this chapter often struggle later in Rotational Mechanics, which is one of the toughest scoring areas in NEET Physics.

This class ensures that you build rock-solid fundamentals so that future chapters become easy and intuitive.

🔥 What You Will Learn in System of Particles – Part 1
1️⃣ Introduction to System of Particles

What is a particle in physics?

Difference between single particle and system of particles

Why we need to study systems instead of individual objects

Real-life examples related to NEET questions

2️⃣ Centre of Mass (COM): Core Concept

Meaning of centre of mass

Physical interpretation

Why motion of COM is important

How NEET frames conceptual questions on COM

3️⃣ Centre of Mass of Discrete Particles

Formula for COM of two particles

COM of multiple particles in 1D, 2D, and 3D

Special cases frequently asked in NEET

Shortcut methods for fast calculation

4️⃣ Centre of Mass of Continuous Bodies

Uniform rod

Ring

Disc

Rectangular lamina

Semi-circular bodies

Understanding symmetry-based shortcuts

5️⃣ Motion of Centre of Mass

Relation between external force and COM motion

Internal vs external forces

Newton’s laws applied to systems

How multiple forces affect COM

6️⃣ Centre of Mass and Newton’s Laws

Applying F = Ma to systems

Why internal forces cancel

External force dominance

NEET conceptual traps

7️⃣ Conservation of Momentum (Introduction)

Momentum of a system

When momentum is conserved

Isolated vs non-isolated systems

Basic numerical problems

(Advanced conservation problems will be covered in Part 2)

8️⃣ Real-Life NEET Applications

Explosion of bodies

Separation of masses

Recoil problems

Two-body motion

System acceleration questions

🎯 NEET Exam-Oriented Learning Approach
