Kepler's Laws

JEE Main asked Kepler's Laws 7 times in 7 of the 108 shifts Lumi analysed, in 2021, 2022, 2023 and 2024. It belongs to Orbital Mechanics, in Gravitation (Physics). The longest wait between two years asking it was 1 year. In 2022 and 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021, 2022, 2023 and 2024. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
