Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the system classification?Automated safety anti-skid braking system
2. What is the conceptual origin?Early principles explored for aircraft braking systems in the 1920s
3. What is an Anti-lock Braking System (ABS)?ABS is a system that stops wheels from locking up so the car can stop safely, especially on slippery roads. It uses sensors and quick brake pressure changes.
4. How does ABS help keep the car from skidding?ABS watches how fast each wheel turns. If a wheel is about to lock, it quickly releases and reapplies brake pressure so the wheel keeps rolling and grips the road.

Wheel Slip: The difference between the linear velocity of the wheel's circumference and the vehicle's actual speed.
Hydraulic Modulator: A component within the ABS that controls the brake fluid pressure to individual wheels.
Friction Coefficient: A measure of the grip between two surfaces, in this case, the tire and the road.
