Oscillations: JEE Main previous year questions
89 questions in 71 of the 108 JEE Main shifts Lumi analysed, asked in 8 of 8 years. Here is what this chapter tests and how.

Questions are counted per shift, out of the 25 each subject has, in the shifts Lumi analysed; papers that offered 30 a subject (2017, 2021–2024) are scaled to 25. Typical range: the middle six of the eight years (2017, 2020–2026), leaving out the single highest and lowest year. The average and the range are historical fact. The weighted estimate is a model: each year's share, with recent years counting more (half-life three years), and chapters NTA dropped from the syllabus set near zero. It is a guide to effort, not a forecast of the paper.

114 of the 168 ideas in Lumi’s map of this chapter have not been asked or touched in the shifts analysed. Of its idea-tagged questions from 2024 on, 29% tested an idea not asked in an earlier year, so learn the whole chapter, not just the list above.
- Simulation: SHM as the shadow of a particle on a circle
- Simulation: Block on a spring: what sets the period?
- Simulation: Two springs, one block
- Simulation: Is it SHM? Plot a against x
- Simulation: Energy in SHM: where K equals U
- Simulation: Simple pendulum: length, g and small swings
Within each subject, chapters in NTA's 2026 syllabus are ranked by their average questions a shift over all 8 years analysed (history, not the model). Going down that list, the chapters that together held the first half of the subject's questions are Must do; the next ones, up to 80%, are Should do; the rest are Lower priority.

Questions a shift, year by year
Out of the 25 Physics questions in a shift. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift.
Raw count: 2017: 1 in 1 shift · 2020: 3 in 12 shifts · 2021: 35 in 24 shifts · 2022: 17 in 24 shifts · 2023: 12 in 12 shifts · 2024: 12 in 18 shifts · 2025: 2 in 8 shifts · 2026: 7 in 9 shifts.

Coverage
How much of the chapter JEE Main has used
We split the chapter into 168 ideas. In the 108 shifts analysed, JEE Main built a question around 43 of them. Most of the chapter has never been the main idea of a question, so past questions alone leave most of it out.
- Asked as the main idea
- 43
- Touched on in a question

- Never asked

Topics
What repeats, topic by topic
This chapter's questions per topic in each year's analysed shifts. The number is the count; the shade is scaled to one shift, so a year with more analysed shifts (1 to 24 a year) does not look darker.

21 ideas inside
Squares are the 8 years with analysed shifts, 2017 to 2026. A number is the questions that year when there is more than one; the shade is scaled to one shift, so a year with more analysed shifts (1 to 24 a year) does not look darker. Share is of the level above.
