Example 1 · difficulty 1/5
A force of magnitude 10 N acts on an object moving through 5 m. If the angle between the force and displacement is 120°, the work done is
- A. 25 J
- B. −25 J
- C. 50 J
- D. −50 J

NEET 2019 Physics Work, Energy and Power Questions
Use this page to connect the official 2019 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
work-energy theorem, conservative forces, power and collisions.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 1/5
A particle moves with uniform speed in a horizontal circle under a centripetal force directed towards the centre. What is the work done by this force over a small displacement along the circle?
- A. Positive, because the force has a nonzero magnitude
- B. Negative, because the force points inward
- C. Zero, because force and displacement are perpendicular
- D. Equal to the product of force and displacement magnitudes
Example 3 · difficulty 1/5
A box slides 6 m east on a rough horizontal floor while a constant frictional force of 5 N acts west. The work done by friction is
- A. 30 J
- B. 0 J
- C. −11 J
- D. −30 J
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 2019 Physics Work, Energy and Power 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 2019 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.
