Core Skills Analysis
Science
- Understanding kinetic and potential energy as the coaster climbs and descends, illustrating energy transformation.
- Applying forces such as gravity, normal force, and friction to explain speed changes on loops and turns.
- Using geometry and measurement to design track angles, loop radii, and calculate safe speed thresholds.
- Practicing the engineering design process: hypothesizing, prototyping, testing, and iterating coaster models.
Tips
Encourage the student to build a paper or foam‑board model of a roller coaster and measure the height of each hill. Have them calculate the potential energy at the top and the kinetic energy at the bottom using ½mv² (assume a standard marble mass). Next, challenge them to redesign a section to reduce friction by adding smooth curves or lubricating the track, then compare speed results. Finally, integrate a short research project on real‑world coaster engineering, focusing on how engineers use computer simulations to ensure rider safety and comfort.
