Exploring Potential and Kinetic Energy in Roller Coasters

The video explains potential and kinetic energy, using a roller coaster as an example. It describes how energy transfers between potential and kinetic forms during a roller coaster ride. The video also provides guidance on building a roller coaster, emphasizing the importance of managing energy to ensure the ride functions correctly.
