Motion Down a Rough Incline

JEE Main asked Motion Down a Rough Incline 4 times in 4 of the 108 shifts Lumi analysed, in 2021, 2024 and 2026. It belongs to Friction, in Laws of Motion (Physics). The longest wait between two years asking it was 3 years. In 2026 it came in more than one shift of the same year.
