F=ma for Single Body

JEE Main asked F=ma for Single Body 9 times in 9 of the 108 shifts Lumi analysed, in 2021, 2022, 2023, 2024, 2025 and 2026. It belongs to Newton's Laws of Motion, in Laws of Motion (Physics). The longest wait between two years asking it was 1 year. 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, 2022, 2023, 2024, 2025 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
