Final answer:
Emergency braking is the act of applying the brakes in a vehicle to come to a sudden stop in order to prevent an accident or respond to a dangerous situation.
Step-by-step explanation:
Emergency braking refers to the act of applying the brakes in a vehicle to come to a sudden stop in order to prevent an accident or respond to a dangerous situation. It is a safety feature that helps to reduce the speed of a moving vehicle quickly and efficiently.
For example, when a driver encounters a sudden obstacle in their path, they can apply the brakes fully to bring the vehicle to a stop as fast as possible. This requires the tires to exert a strong frictional force against the road, converting the vehicle's kinetic energy into heat energy. The faster the vehicle is moving, the longer it will take to come to a complete stop.
Emergency braking can be facilitated by various braking systems, such as hydraulic brakes or regenerative brakes in hybrid and electric vehicles. These systems utilize different mechanisms to slow down or stop the vehicle in an emergency situation.
