Question 845 in the bank

While turning, what natural force pushes the vehicle against the direction of the turn?

  1. Gravity.
  2. Correct answer: Centrifugal force.
  3. The force of inertia.
  4. None of the natural forces affect the vehicle while turning.

Why this is the answer

The correct answer in the official bank: Centrifugal force.

When a vehicle goes through a turn, centrifugal force acts on it, pushing it toward the outside of the curve. This force grows with higher speed, a sharper turn and a heavier vehicle. If it exceeds the tyres' grip on the road, the vehicle may skid or even roll over. That is why you should slow down before entering a turn, not in the middle of it.
