When is a vehicle affected by centrifugal force?
- While driving in a straight line, even when the road is horizontal.
- Correct answer: While driving around curves and turns.
- While driving straight in steep uphill climbs.
- While driving straight in steep descents.
Why this is the answer
The correct answer in the official bank: While driving around curves and turns.
Centrifugal force appears only when a vehicle changes direction, as on curves and turns. It pushes the vehicle toward the outside of the bend and grows sharply with higher speed and tighter curves. Driving straight, even on steep climbs or descents, involves no change of direction, so this force does not act. That is why you should slow down before entering a curve.
