Thames & Kosmos, Roller Coaster Engineering 625417

The Roller Coaster Engineering set allows you to build and experiment with dozens of roller coaster models, making learning the physics of force, motion, and energy as fun as a day at the amusement park. With an easy modular building system, you can piece together sturdy frame structures and attach flexible tracks to build and test endless roller coaster designs. By varying the weight of the cars and the slope length and direction of the track, you can explore physics principles such as gravitation, potential energy, kinetic energy, free fall, projectile motion, friction, centripetal force, velocity, and acceleration. The set also includes engineering challenges, a full-color manual with step-by-step instructions, and the opportunity to design and build your own roller coaster.
