Constrained Motion

JEE Main asked Constrained Motion 3 times in 3 of the 108 shifts Lumi analysed, in 2021 and 2022. 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 2022 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021 and 2022. 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

Diagram based is the usual form. Skill tested: multi-step.

  • Force on system with string-pulley constraint
  • Constraint relation for multi-pulley accelerations
