Driving on Ice

Winter is here, and so is the snow. Many people fear driving on wet icy roads, and for good reason. The coefficient of kinetic friction between rubber and ice is 0.15, while the kinetic coefficient between rubber and dry asphalt is 0.72. Since the force of friction is directly related to these coefficients, the force of friction helping a car stop is nearly 5 times less when driving on icy roads, and therefore the net force is drastically reduced. All of this means less acceleration, meaning people need to drive slower and brake sooner to stay safe in bad weather.
