AC Circuits: Impedance and Phase Shift
Compare R, RC, RL, and RLC circuits, phase shift, impedance, and resonance.
Send a Message to Earth
Send signals Earth-Mars and measure delay from distance and light-speed limits.
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.
