NEET 2016 Physics Rotational Motion Questions
Use this page to connect the official 2016 paper with current Physics practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
centre of mass, torque, angular momentum, rolling and moment of inertia.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
The moment of inertia of a uniform rod of mass M and length L about a perpendicular axis through one end is ML²/3. Its moment of inertia about a perpendicular axis passing through a point at a distance L/4 from one end of the rod is:
- A. ML²/12
- B. 7ML²/48
- C. ML²/16
- D. 5ML²/48
Example 3 · difficulty 3/5
A student on a frictionless rotating stool spins with angular speed ω while holding dumbbells in outstretched hands. She pulls her arms in, reducing the moment of inertia of the system to half its initial value. The ratio of her final rotational kinetic energy to the initial rotational kinetic energy is:
- A. 1 : 1
- B. 4 : 1
- C. 1 : 2
- D. 2 : 1
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2016 Physics Rotational Motion PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2016 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
