Final answer:
In the context of high school Physics, the aid of friction between the tires and the road helps a vehicle maintain control and avoid wheel lock-up by providing the necessary horizontal centripetal force for turning on a curve.
Step-by-step explanation:
The subject in question is related to Physics, specifically the concept of centripetal force and friction.
When a vehicle turns on a curve, the net external force on the car is the horizontal centripetal force that is required for circular motion. The ideal speed is the maximum speed at which a vehicle can safely navigate a curve, relying on the friction between the tires and the road.
To maintain control and prevent wheel lock-up, systems such as Anti-lock Braking System (ABS) utilize the principles of physics to aid in safe driving.
In the absence of friction, it would be impossible for the vehicle to turn at all, as friction provides the necessary force to keep the vehicle on its curved path.
The 'aid of friction between the tires and the road' is essential for maintaining control and avoiding wheel lock-up, ensuring the vehicle can turn safely without skidding or losing traction.
