As per your syllabus, when a stationary bus suddenly starts, passengers are jerked backward primarily because of which property?
ACentripetal acceleration
BConservation of momentum
CAction and reaction pair
DInertia of rest
Answer & Solution
Correct answer: D. Inertia of rest
Your syllabus: while feet move with bus, upper body lags due to inertia of rest.
Jerk = transient relative motion before muscles act.
