Final answer:
Worn or bald tires are dangerous because they have reduced grip on the road, which can lead to a loss of control of the vehicle. Friction, on the other hand, can be desirable in certain situations.
Step-by-step explanation:
The correct answer is option Physics.
Worn or bald tires are dangerous because they have reduced grip on the road, which can lead to a loss of control of the vehicle.
When the tire tread wears down, it becomes smooth and less able to grip the road, especially in wet or icy conditions. This increases the risk of skidding and accidents.
Friction, on the other hand, can be desirable in certain situations. For example, when walking on a slippery surface, like ice, having high friction between your shoes and the surface can help prevent slipping and provide stability.
The correct answer is option: Worn or bald tires are dangerous because they significantly reduce the traction of a tire on the road surface, which can lead to increased stopping distances and a higher likelihood of losing control, especially in adverse weather conditions such as rain or snow.
Tires with adequate tread depth create more friction with the road, providing the necessary grip to brake, steer, and accelerate safely. Another situation where increased friction is desirable is when an athlete uses running shoes with good treads for better grip during a race or on the playing field to prevent slipping.
