Worked Solution & Example Answer:The force of friction exists between the tyres of a car and the surface of a road - Junior Cycle Science - Question g - 2017
Step 1
How can this force be useful to a driver?
Answer
The force of friction between the tyres and the road is crucial for a driver. It provides better tyre grip, ensuring that the car maintains control and stability while driving. This grip allows for effective road holding, enabling the car to navigate turns without skidding. Additionally, friction is essential for braking, as it slows down the car safely when the brakes are applied.
Step 2
Explain how friction affects the tyres.
Answer
Friction affects the tyres in several ways. It causes wear and tear on the tyre surface, leading to gradual damage over time. Additionally, as friction generates heat, the tyres tend to get hot during use. Excessive heat can further accelerate wear and may affect the structural integrity of the tyres if not managed properly.
