the relationship between A is proportional to B.

(ii) the car is accelerating with constant acceleration.

the relationship between A and B is A is not proportional to B in this case.

i.e., Force A = Force B

ii) During acceleration,

Force A < Force B

b) Along the radius of the corner curve (I am not very certain about this part)
