Torque & Rotational Equilibrium
Interactively balance forces on a rigid lever by placing masses at different distances from the pivot. Observe torque magnitudes and directions, and understand the condition for rotational equilibrium.
Buoyancy & Archimedes Principle
Drop objects of different densities into fluid of adjustable density. Observe buoyant force, weight, and net force to predict whether objects sink, float, or remain neutrally buoyant — all in 3D.
Riemann Sum Explorer
Interactively approximate definite integrals using left, right, and midpoint Riemann sums. Adjust the number of rectangles to watch the approximation converge to the true area under the curve.
Derivative & Tangent Line Visualizer
Drag a point along any differentiable function to see the tangent line update in real time. Visualize how the slope of the tangent equals the derivative value, and explore where derivatives are zero or undefined.
Slope Field Explorer
Generate slope fields for any first-order ODE and trace solution curves through arbitrary initial conditions. Visualize how solutions behave near equilibria, and develop intuition for qualitative analysis.
VSEPR Molecular Geometry
Explore 3D molecular geometries for common electron-domain configurations. Rotate and inspect tetrahedral, trigonal planar, linear, octahedral, and bent structures. Understand how lone pairs distort ideal bond angles.
Normal Distribution Explorer
Adjust mean and standard deviation to see how the normal distribution bell curve shifts and stretches. Shade probability regions to compute areas under the curve and connect z-scores to percentiles.
Thin Lens Equation Simulator
Construct dynamic ray diagrams for converging and diverging lenses. Analyze real/virtual image formation using the thin lens equation and magnification formulas.
Photoelectric Effect
Experiment with the quantum nature of light. Adjust wavelength, intensity, target metal, and stopping potential to verify the Einstein photoelectric equation.
Transformer Principles
Simulate an ideal transformer using Faraday's Law. Adjust primary/secondary turns and voltages to see magnetic flux transfer and conserve power.
LC Circuit Oscillations
Visualize the differential oscillation of energy between an inductor's magnetic field and a capacitor's electric field. Live graphs of charge and current.
Carnot Cycle Explorer
Trace the ideal thermodynamic Carnot Engine. Calculate P-V diagram work area, thermodynamic efficiency, and heat transfer across isothermal and adiabatic processes.
