Final answer:
The primary reason for loss of traction while driving on snow is the reduced friction between tires and icy roads. Winter tires are designed to increase friction and ensure better grip. Athletes also require increased friction for stability and control in their respective sports.
Step-by-step explanation:
While driving on snow, the most common reason for loss of traction is the reduced friction between the tires and the icy road surface. This loss of friction can be attributed to a thin layer of water created by the heat of the tires melting the snow or ice, leading to a slippery surface condition known as 'black ice.' To combat this, winter tires are engineered with specialized tread patterns and compounds to create more friction and grip on icy surfaces.
Another example where more friction is desirable is in sports like basketball or track, where athletes rely on the grip of their shoes to perform quick maneuvers without slipping. Here, the increased friction between the shoe and the court or track helps players maintain control and stability during the game or race.
Despite advancements in vehicle efficiency such as cars becoming more fuel efficient and achieving more miles to the gallon, winter driving conditions require careful consideration of the right equipment to maintain safety. Moreover, exceptionally cold winters make it even more critical to use winter tires to maintain proper traction on icy roads.
