AC Circuits: Impedance and Phase Shift
Compare R, RC, RL, and RLC circuits, phase shift, impedance, and resonance.
Kepler's Laws
Test Kepler's laws by changing orbit shape, area sweep, and period-distance relation.
All Simulations
Build the Nucleus
Build isotopes, vary N/Z ratio, and test which nuclei remain stable.
Buoyancy: why does it float or sink?
Test buoyancy in liquids and predict when objects float, sink, or stay suspended.
