Build the Nucleus
Build isotopes, vary N/Z ratio, and test which nuclei remain stable.
AC Circuits: Impedance and Phase Shift
Compare R, RC, RL, and RLC circuits, phase shift, impedance, and resonance.
All Simulations
Buoyancy: why does it float or sink?
Test buoyancy in liquids and predict when objects float, sink, or stay suspended.
Capacitor: Field, Energy, and RC Charging
Charge and discharge an RC circuit, then track capacitance, field, and time constant.
