Work-Energy Theorem

JEE Main asked Work-Energy Theorem 10 times in 10 of the 108 shifts Lumi analysed, in 2017, 2020, 2022, 2023, 2024 and 2026. It belongs to Work and Kinetic Energy, in Work, Energy and Power (Physics). The longest wait between two years asking it was 3 years, across 2018 and 2019, which Lumi has no shifts for. In 2022, 2023 and 2026 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2017, 2020, 2022, 2023, 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.

How JEE Main framed it

Single correct is the usual form. Skill tested: calculation.

  • Work from velocity as function of position
  • Average force from work-energy theorem
