Optional Information

Answer

Hello XXXXXXXXXX,

Friction opposes motion causing moving objects to slow down.

Friction wheels are added to a roller coaster to prevent movement to the side of the track.

A roller coaster is driven by changes in energy (no engine is needed). So the energy changes are the greatest factor affecting the design.
