The author uses the term centripetal force in the paragraph to name the type of force being explained in relation to roller coasters. This choice clearly defines the specific force at play when a roller coaster navigates curves and loops, helping readers understand the physics behind the experience.
Read the paragraph from "The Physics of Scream Machines."
When a roller coaster has a sudden banked curve or loop, other forces of physics come into play. Moving objects tend to continue moving at the same speed and in the same direction until acted upon by another force. According to the laws of physics, any motion in a curved path needs a force directed toward the center of the curved path. This force is called the centripetal (center-seeking) force. When you travel around a curve or through a loop in a roller coaster, you can experience this force pushing the car in a circle. It will feel as if your body is being pushed to the left or right or—in the case of a loop—toward the floor of the car, even when you are completely upside down.
