On a roller coaster, the cars are in free fall when they are going down hill and not run by a motor.

Kadjer was pretty much right but to better explain. Once a rollar coaster is brought up the first hill it no longer uses any motor throughout the rest of the ride. The initial drop down the first hill gives it enough momentum to get it up the next hill. The next hill just adds more momentum getting it up the hill that follows, etcetera

I think that since they're father told them to meet at the entrance..The kids might not have money to get the entrance ticket so that it is impossible for them to take any amusement ride if they don't have the gate pass...

The father might have tested the boys separately with a question about the incident. Based the how they answer he could have know that they are lying

the roller coaster going downhill accelerates due to gravity and not the engine.

If the roller coaster was going downhill, the engine wouldn't hve to work hard. gravity brings it down. Therefore, the engine wouldn't burn out going downhill.

roller coaster while coming down will use the potential energy due to the height achieved, so the engine will hardly have any role to play in this.

Maybe it is cause the boys weren't at a certain height to get on a rollercoaster

Roller coaster only uses engine on the first climb. Once it starts it will get through the entire ride from the initial momentum, even if the engine "blew out".

In general, most roller coasters don't HAVE motors, and even if they DID, they'd only NEED them on the uphills! Thus, the kids' answer doesn't make any sense! :-/
