NEET 2017 Physics Gravitation Questions
Use this page to connect the official 2017 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
fields, potentials, satellites, escape speed and orbital energy.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 3/5
A satellite of mass m is in a circular orbit of radius r around the Earth (mass M). If the total mechanical energy of the satellite is −E, its gravitational potential energy in the orbit is:
- A. −2E
- B. −E
- C. −E/2
- D. +2E
Example 3 · difficulty 4/5
A satellite revolves in a circular orbit of radius r around a planet of mass M with orbital speed v. The minimum additional speed that must be imparted to the satellite, in its direction of motion, so that it just escapes the planet's gravitational field is:
- A. v
- B. (√2 + 1)v
- C. (√2 − 1)v
- D. √2 v
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 2017 Physics Gravitation 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 2017 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.
