AC Circuits: Impedance and Phase Shift
Compare R, RC, RL, and RLC circuits, phase shift, impedance, and resonance.
Charges and Fields
Place point charges, explore electric field direction and magnitude, and see superposition in action.
All Simulations
Apollo Parachute Descent
Configure Apollo’s parachute descent and see how deployment timing and Euler’s method affect a safe splashdown.
Apollo: Re-entry
Test Apollo return trajectories, hit the safe corridor, and see why mathematics and computation mattered for bringing the capsule home.
