SHM Definition and Force Law

JEE Main asked SHM Definition and Force Law 5 times in 5 of the 108 shifts Lumi analysed, in 2021, 2023, 2024 and 2025. It belongs to SHM Equations, in Oscillations (Physics). The longest wait between two years asking it was 2 years. 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, 2023, 2024 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
