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

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.

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