Displacement in the nth Second

JEE Main asked Displacement in the nth Second 6 times in 6 of the 108 shifts Lumi analysed, in 2021, 2022, 2024 and 2026. It belongs to Kinematics in 1D, in Motion in a Straight Line (Physics). The longest wait between two years asking it was 2 years. In 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, 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
