This lecture tackles complete (perfectly inelastic, elastic )collision the way NEET actually tests it—through conservation laws, logic, and question patterns, not decorative formulas. Dr Deepak Sinhmar explains the concept from first principles and then stress-tests it with exam-oriented numerical and conceptual questions.

The session clearly differentiates elastic, inelastic, and completely inelastic collisions, with special focus on what “complete” really means: bodies stick together after collision, momentum is conserved, kinetic energy is not, and maximum energy loss occurs. Every assumption is made explicit so students stop making silent mistakes in MCQs.

Key ideas like common velocity after collision, loss of kinetic energy, coefficient of restitution (e = 0), and real-life physical interpretation are derived step by step and then applied directly to NEET-level problems. Typical traps—blindly applying energy conservation or mixing collision types—are called out and dismantled.

The question discussion segment focuses on shortcuts, sign conventions, and decision-making under time pressure, exactly what separates average attempts from high scores.

Ideal for Class 11 & 12 students, NEET 2026 aspirants, and anyone who understands formulas but loses marks in application.

Collisions are not about memorizing cases. They’re about respecting conservation laws—and NEET rewards those who do.
