Final answer:
In an emergency situation with conventional brakes, you must apply the brakes firmly and quickly. Releasing the brake pedal slightly allows the car to transition from static to kinetic friction, preventing a motion while stopping.
Step-by-step explanation:
In emergency situations with conventional brakes, it is crucial to promptly and firmly apply the brakes to generate a high frictional force between the brake pads and rotors, effectively slowing down or halting the vehicle.
The interplay between static and kinetic friction becomes significant as you gradually release the brake pedal when nearing a stop.
Initially, static friction impedes wheel rotation upon brake application.
As the car decelerates and the wheels approach a complete halt, static friction diminishes, giving way to kinetic friction between the brake pads and rotors.
Modulating the brake pedal by slight release reduces pressure on the braking components, facilitating a smooth transition from static to kinetic friction.
This action prevents an abrupt stop and mitigates the risk of a motion, contributing to a more controlled and safe deceleration process.
