Escape Velocity

JEE Main asked Escape Velocity 8 times in 8 of the 108 shifts Lumi analysed, in 2020, 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 2021, 2023 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 2020, 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.
