Which sentence BEST states the central idea of the first paragraph of "Roller Coaster Physics"?

A. Potential energy is created by the lift hill.

B. Gravity is the force that makes roller coasters possible.

C. Kinetic and potential energy work together to power roller coasters.

D. Potential energy builds as a train car goes up the lift hill, while gravity pulls a train car down the tracks.

Answers

Answer 1

The first paragraph of "Roller Coaster Physics" shows the main idea that the potential energy increases as the roller coaster climbs the hill, while gravity pulls the roller coaster along the tracks.

We can arrive at this answer because:

"Roller Coaster Physics" is an article that wants to show you how a roller coaster works.The first paragraph makes it clear how gravity and potential energy play a role in the functioning of the roller coaster.This is because, in the first paragraph of the article, we can see that the moment the roller coaster is going up the hill is the moment it is building a reservoir of potential energy.This energy will be transformed into kinetic energy when the roller coaster starts going downhill.However, what pulls the roller coaster downhill is gravity.

With this, we can see that the higher the roller coaster can go, the more potential energy it accumulates and the greater the intensity of gravity on it.
