Description
🔍 Explore
Follow a skater’s kinetic, potential and thermal energy on different tracks.
🎮 Try It
Play, pause, step or return the skater, and change friction. Show speed, a grid or the energy pie chart. Use Measure to read height and energy, Graphs to record changes, or Playground to choose gravity, mass and a track that you can reshape.
🎯 Your Mission
Build a Playground track where the skater reaches a chosen second hill without leaving the track. Predict the minimum starting height, then test and refine your design.
🌍 Real-World Connection
Roller coasters gain speed downhill and trade that motion for height uphill.
