(A)

Front view of a car rounding a curve with constant speed.

(P) ${\vec{F}}_1+{\vec{F}}_2+{\vec{F}}_3$ is centripetal force.

(B)

Passengers in a rotor not sliding relative to rotor wall cylindrical rotor is rotating with constant angular velocity about its symmetry axis.

(Q) ${\vec{F}}_1$ is static friction.
