Final answer:
People who ride a roller coaster at a theme park constitute a sample of the entire theme park population, as they are a subset that has engaged in a specific activity. Roller coasters are designed based on principles of physics, using potential and kinetic energy as well as centripetal forces.
Step-by-step explanation:
In the context of a theme park, the population represents all the people who visit the park, while a sample is a subset of the population that is used to represent the entire group. If we consider people who ride a roller coaster, they would represent a sample of the entire theme park population.
This is because they are a subset of all visitors, chosen by the criteria of choosing to ride the roller coaster. Understanding this concept is important in fields like statistics and scientific research where samples are used to infer characteristics about a whole population.
Roller coasters utilize principles of physics to deliver thrills, based on the conversion of potential energy into kinetic energy and the use of centripetal forces during loops.
For instance, the car is slowly lifted to the top of the ride, where it gains maximum potential energy before converting it into kinetic energy as it descends and traverses through various elements of the track.
Additionally, when a coaster goes through a vertical loop, gravity provides the centripetal force necessary for the car to maintain contact with the track, which is an example of Newton's laws of motion and energy transformations in action.
