Energy Conservation in Vertical Circles
JEE Main asked Energy Conservation in Vertical Circles 2 times in 2 of the 108 shifts Lumi analysed, in 2021 and 2026. It belongs to Work and Kinetic Energy, in Work, Energy and Power (Physics). The longest wait between two years asking it was 5 years.

Questions on this idea a shift, by year
2017–2026. Asked in 2021 and 2026. 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: 1 in 24 shifts · 2022: 0 in 24 shifts · 2023: 0 in 12 shifts · 2024: 0 in 18 shifts · 2025: 0 in 8 shifts · 2026: 1 in 9 shifts.

How JEE Main framed it
Numerical value is the usual form. Skill tested: calculation.
- Release height for loop-the-loop condition
