While braking and slowing down, what force of nature is applied on the vehicle?
- No force of nature affects the vehicle while it is braking or slowing down.
- Correct answer: The force of inertia, i.e. the force which causes the vehicle to continue moving.
- The centrifugal force, i.e. the force applied on the vehicle when it is turning.
- The lift force, i.e. the force that pulls the vehicle upwards.
Why this is the answer
The correct answer in the official bank: The force of inertia, i.e. the force which causes the vehicle to continue moving.
When braking or slowing down, the vehicle and its passengers tend to keep moving forward because of the force of inertia, so the vehicle does not stop immediately. This is the force that causes the vehicle to continue moving. The centrifugal force acts on the vehicle when turning, not when braking in a straight line.
