Learn by doing
Explore, experiment, and build intuition. These interactive tools bring engineering concepts to life—one experiment at a time.
Georgia Tech · AE 2220 · Dynamics
Final Project
Start on the road. Take flight. Build from wheel forces to thrusters, flips, and full three-dimensional dynamics.
Developer: Bolei Deng · Proof reading: Victor Riera Naranjo
Kinematics in Motion Rigid-body kinematics
Bring textbook problems to life with nine interactive examples. Explore moving linkages, rolling wheels, and rotating bodies, and see how velocity and acceleration change at every point.
Runs in your browser · No installation needed
Choose an example, press Play, and follow a point on the moving body. Pause at any instant to inspect its velocity and acceleration, then change the inputs to see what happens.
Ignition Lab Rockets & momentum
Build a rocket, choose your propellant, and steer your payload into an unpowered orbit. Explore how thrust, mass, and fuel choices shape your flight and its cost.
Runs in your browser · No installation needed
Launch your rocket and turn gradually toward the horizon. Cut the engine to test whether your orbit holds, then try reaching orbit with less propellant.
Orbit Lab Orbital mechanics
Take the controls of a satellite. Change its velocity, preview a maneuver, and watch its orbit evolve around Earth in three dimensions.
Runs in your browser · No installation needed
Start with a circular orbit, try a prograde burn, and see how the path changes. Switch to the 3D view to explore a maneuver out of the orbital plane.
Pacing Lab Mechanics & energy
Take on a hilly cycling course—or import your own GPX and choose a segment. Control your power, manage your energy reserve, and discover how pacing changes your finish time.
Runs in your browser · No installation needed
Ride once at a steady 330 W, then try pushing harder on climbs and coasting downhill. Compare your finish times and watch how your energy reserve recovers.
Apex Lab Friction & cornering
Race down a winding descent with one control—the brake lever. Balance braking and cornering within the available tire grip, and find your fastest clean run.
Runs in your browser · No installation needed
Try braking before a bend, then compare with braking during the turn. Watch the traction circle to see how braking and cornering share the same grip limit.
A growing collection of tools for the classroom and your own curiosity.
