Launch angle, speed and range
Simulation results shown in the values and measurements below.
Pin the current parameters, then change a variable to see both predictions. Dotted purple = baseline.
No baseline pinned for this experiment.
Investigate how changing velocity, gravity, mass, focal length, resistance, frequency and other parameters changes a physical system. The PixelOkay lab runs six educational models in your browser. Play, pause, step through time, compare numerical outcomes and export observations.
Projectile motion and free fall use ideal kinematics. Collisions demonstrate linear momentum and restitution in one dimension. Optics models a thin converging lens. Electricity models simple series and parallel DC resistor networks. Waves demonstrate a single traveling sine wave. Each experiment clearly states its simplifying assumptions.
No. The simulator runs with HTML, CSS and JavaScript alone. Save your project file to keep your variable settings and observations and reopen it later.
Select an experiment, adjust its parameters and compare a pinned baseline. Log predicted values or export a modeled data series, then save project JSON to keep the experiment settings.
These are educational idealizations rather than sensor measurements or engineering-certified simulations. Model assumptions vary by experiment; the electricity view is a simple resistor model rather than a general circuit solver. Browser recovery is best effort.
This is an authored comparison exercise, not a physical measurement or independently validated trajectory.
No. They are predictions from educational models with simplifying assumptions. They do not establish sensor readings, uncertainty estimates or engineering-certified results.
No. It is a simple resistor model, not a general circuit solver. Inspect each experiment's assumptions and keep project JSON when you need to repeat the same supported setup.
