While braking and slowing down, what force of nature is applied on the vehicle?

1. No force of nature affects the vehicle while it is braking or slowing down.
2. Correct answer: The force of inertia, i.e. the force which causes the vehicle to continue moving.
3. The centrifugal force, i.e. the force applied on the vehicle when it is turning.
4. The lift force, i.e. the force that pulls the vehicle upwards.

WhyWhen you brake, inertia pushes the vehicle forward. Centrifugal force acts in bends.
