Trace energy through working machines and forces through the structures around us. Change a load, inspect the parts and test what the model can explain.
Interactive explorationTurn a tabletop generator, unplug its lamp, and replay the same motion. Follow the voltage, the pushback and every joule to discover where electrical energy comes from.
Interactive explorationTurn a source-shaped blade, change the generator load and follow the energy. Discover why pitch, torque and speed must work together—and compare a model with a real wind-tunnel experiment.
Interactive explorationConnect a realistic module to a virtual load, look inside a silicon cell, and build a day’s energy from changing light and time.
Power a motor. Reverse its direction. Add a load and watch speed, current and turning force find a new balance.
Turn once. Count what happens. Discover gear ratios, real-world uses, and why different jobs need different gears.
Interactive explorationMove a load across an inspectable steel truss. Lift its deck, catch a diagonal changing from push to pull, repair a missing restraint and follow forces all the way to the supports.
Interactive explorationMake a wheel see-through, follow a marked ball and test which motions can roll. Then discover why a longer spin does not always mean less friction.
