Why Roller Coasters Are Awesome!

The video explores the workings of roller coasters, focusing on the forces involved, such as gravity and friction. It explains how roller coasters move without motors, using chains and gravity, and how friction eventually slows them down. The video also touches on the design considerations for ensuring roller coasters have enough speed to complete their course. Finally, it concludes with a readiness to explore the fair.
