Final answer:
When going uphill on an ice-covered road, it is important to consider the effect of friction on the tires. Friction plays a crucial role in maintaining traction and preventing the vehicle from sliding backwards. Using snow tires or tire chains can help improve traction on icy surfaces.
Step-by-step explanation:
When going uphill on an ice-covered road, it is important to consider the effect of friction on the tires. Friction is the force that opposes motion between two surfaces in contact. In this case, the friction between the tires of the vehicle and the icy road is crucial for maintaining traction and preventing the vehicle from sliding backwards.
On an ice-covered road, the tires have reduced grip due to the lack of friction. This means that the vehicle needs more force to overcome the increased resistance and climb the hill. The tires might spin and slip on the ice, making it difficult to maintain forward motion.
To improve traction and overcome the lack of friction on an ice-covered road, it is advised to use snow tires or tire chains. Snow tires have specialized tread patterns and compounds that enhance grip on icy surfaces. Tire chains provide additional traction by biting into the ice and snow, increasing friction between the tires and the road.
