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. How high is Track transition curve?Gradually introduces cant (banking) to counteract lateral forces
2. What is the primary engineering objective?To ensure a continuous and gradual variation of centripetal acceleration
3. What is the key design parameter?Maximum allowable lateral acceleration for passenger comfort and safety

Clothoid: A spiral curve where the rate of change of curvature is constant with respect to arc length.
Centripetal Acceleration: The acceleration vector directed towards the center of a curved path, responsible for changing the direction of velocity.
Superelevation (Cant): The transverse inclination of a railway track or roadway, achieved by raising the outer rail or edge higher than the inner one.
