Fractional Energy Displacements
JEE Main asked Fractional Energy Displacements 3 times in 3 of the 108 shifts Lumi analysed, in 2021 and 2023. It belongs to Energy in SHM, in Oscillations (Physics). The longest wait between two years asking it was 2 years. In 2021 it came in more than one shift of the same year.

Questions on this idea a shift, by year
2017–2026. Asked in 2021 and 2023. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
Raw count: 2017: 0 in 1 shift · 2020: 0 in 12 shifts · 2021: 2 in 24 shifts · 2022: 0 in 24 shifts · 2023: 1 in 12 shifts · 2024: 0 in 18 shifts · 2025: 0 in 8 shifts · 2026: 0 in 9 shifts.
