Example 1 · difficulty 2/5
In a force-position graph, the force is 4 N from x = 0 to x = 2 m. It then decreases linearly from 4 N at x = 2 m to zero at x = 5 m. What is the work done from x = 0 to x = 5 m?
- A. 6 J
- B. 8 J
- C. 20 J
- D. 14 J

NEET 2021 Physics Work, Energy and Power Questions
Use this page to connect the official 2021 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 2/5
A force-position graph consists of a triangular region above the x-axis from x = 0 to 4 m with maximum height 6 N, followed by a constant force of −2 N from x = 4 m to 6 m. Find the net work.
- A. 8 J
- B. 16 J
- C. 12 J
- D. 4 J
Example 3 · difficulty 3/5
On a force-position graph, the force varies linearly from −2 N at x = 0 to 6 N at x = 4 m. What is the work done over this interval?
- A. −8 J
- B. 8 J
- C. 10 J
- D. 16 J

Frequently asked questions
Are these official NEET 2021 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 2021 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.
