Interactive Concepts

Drag-to-explore visualizers for the math, physics, and chemistry ideas students meet most. Every one is free to use in the browser, and exports to an image, GIF, or MP4 for your slides and handouts.

Math

Unit Circle interactive preview
Unit CircleDrag the angle to read sine, cosine, and tangent, with a full common-angle chart.
Slope-Intercept Form interactive preview
Slope-Intercept FormDrag m and b to reshape the line y = mx + b and read its intercepts.
Quadratic Function interactive preview
Quadratic FunctionDrag a, b, and c to reshape a parabola and mark its vertex, roots, and discriminant.
Exponential Function interactive preview
Exponential FunctionDrag a and the base b to switch between exponential growth and decay.
Systems of Equations interactive preview
Systems of EquationsDrag two lines to find where they intersect — one, none, or infinitely many solutions.

Physics

Projectile Motion interactive preview
Projectile MotionDrag the launch angle and speed to reshape the trajectory, range, and maximum height.
Simple Harmonic Motion interactive preview
Simple Harmonic MotionDrag the amplitude and period to reshape the sine wave and read the frequency.

Chemistry

Electrolysis of Water interactive preview
Electrolysis of WaterWatch an electric current split water into hydrogen and oxygen gas in 3D.
Combustion Reaction interactive preview
Combustion ReactionWatch methane burn — CH₄ + 2O₂ → CO₂ + 2H₂O — as bonds break and re-form.
Balancing Chemical Equations interactive preview
Balancing Chemical EquationsAdjust coefficients and watch the atom counts on each side balance out.
