AC Circuits: Impedance and Phase Shift
Compare R, RC, RL, and RLC circuits, phase shift, impedance, and resonance.
Lever: torque and balance
Balance the lever, vary force and arm length, and see torque 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.
