HC Verma Ch 5 Ex42 | Elevator Falls Faster Than Gravity | Tricky Motion Problem

Описание: This video solves a very deceptive HC Verma Laws of Motion problem that many IIT JEE and NEET students answer wrongly on the first attempt.

A block is kept on the floor of an elevator initially at rest. Suddenly, the elevator starts descending with an acceleration greater than gravity. The key question is 👇
What happens to the block during the first 0.2 seconds?

In this video, you will clearly understand
• What it means when elevator acceleration is greater than g
• Whether the block stays in contact with the floor or not
• How normal reaction changes in an accelerating elevator
• Why free fall conditions appear instantly
• How to correctly calculate displacement in a short time interval

This problem is not just about formulas. It tests your conceptual clarity of
Non inertial frames
Contact forces
Free fall
Relative motion
Application of Newton’s laws

I explain the solution step by step with proper physical reasoning, so you never confuse such elevator problems again.

Perfect for

IIT JEE Main and Advanced
NEET Physics
Concept strengthening and revision

📌 Watch till the end to avoid one of the most common conceptual mistakes students make in elevator questions.
