Engineering the Thrills of Roller Coasters: Forces and Energy Explained

The video explores the engineering behind roller coasters, focusing on the roles of civil engineers in designing these thrilling rides. It explains the physics of roller coasters, including gravity, potential energy, and kinetic energy. The video also discusses how energy is lost through air resistance and friction, and the importance of safety measures like harnesses and seatbelts. Finally, viewers are encouraged to learn more and design their own roller coasters.
