F pseudo = −m × a frame

N elevator = m(g ± a)

F centrifugal = mω²r

F Coriolis = 2mωv

F turning = mv²/R

Reverse the bus acceleration and watch the pseudo-force arrow reverse.
Set elevator acceleration to negative 9.8 m/s² conceptually and predict weightlessness.
Double angular speed and compare centrifugal force.
Reduce turn radius while holding speed fixed.
