Final answer:
When roads are slippery, careful turning is key, tires with higher friction are necessary for better traction, and easing off the brake pedal engages static friction for a smoother stop.
Step-by-step explanation:
When roads are slippery, the most important driving technique is to make turns as carefully as possible to prevent loss of control. Using tires designed for icy roads increases the friction between the tire and the road surface, which is crucial for maintaining grip. An example where more friction is desirable besides icy road conditions would be in sports such as track and field, where athletes use shoes with spikes to increase traction and improve performance.
In terms of driving dynamics, the relationship between static and kinetic friction is critical. When you ease up on the brake pedal before coming to a stop, you're taking advantage of the higher static friction between the tires and the road, which helps prevent the wheels from locking and the car from stopping abruptly. Lastly, if a car encounters a patch of ice and slides off the road, it typically follows a path in the direction it was moving before encountering the ice due to the low coefficient of kinetic friction, which offers minimal resistance to the car's momentum.
