The faster you are traveling, what do you need more of to stop?

Answer: B — More friction

As your speed increases, the kinetic energy of your vehicle also increases, which means it requires more energy to bring the vehicle to a stop. Friction between the tires and the road is what allows your vehicle to slow down or stop effectively. When traveling at higher speeds, you need more friction to overcome that increased kinetic energy and bring the car to a halt safely. If there's not enough friction available, the vehicle may not stop in time, leading to potential accidents. This highlights the importance of maintaining proper tire conditions and understanding road conditions, especially in adverse weather. As speed increases, it's crucial for drivers to be aware of how much more friction they need to ensure safe stopping distances.
