NEET 2018 Physics Work, Energy and Power Questions

Use this page to connect the official 2018 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 1 · difficulty 3/5

A small stone tied to a string is whirled in a vertical circle of radius 0.9 m so that it just completes the loop. Taking g = 10 m s⁻², the minimum speed of the stone at the highest point of the circle is

  • A. 9 m s⁻¹
  • B. 3 m s⁻¹
  • C. 6.7 m s⁻¹
  • D. 1.5 m s⁻¹

Example 2 · difficulty 4/5

A 2 kg block moving at 6 m s⁻¹ on a smooth horizontal floor overtakes and collides head-on with a 4 kg block at rest. The blocks stick together after the impact. The kinetic energy converted into heat, sound and deformation during the collision is

  • A. 36 J
  • B. 12 J
  • C. 9 J
  • D. 24 J

Example 3 · difficulty 1/5

A constant force F = (3 i + 4 j) N acts on a particle that undergoes displacement s = (2 i − j) m. What is the work done by the force?

  • A. 2 J
  • B. 10 J
  • C. 14 J
  • D. 5 J

The evidence-first practice loop

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2018 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 2018 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.
