Conservation of Energy
Watch a ball roll down a curved ramp as kinetic and potential energy interchange in real time. Adjust mass, release height, and friction to see how energy distributes across KE, PE, and thermal bars. Discover why total mechanical energy is constant without friction.
Elastic & Inelastic Collisions
Fire two balls toward each other and observe elastic, inelastic, and perfectly inelastic collisions. Adjust masses, initial velocities, and the coefficient of restitution. Before-and-after momentum and kinetic energy tables verify conservation laws in real time.
Pendulum Oscillation
Explore a 3D pendulum with adjustable length, mass, initial angle, gravity, and damping. Watch the θ(t) graph update live and discover that period depends only on string length and gravity — not mass. Try Moon, Mars, and Jupiter gravity settings!
Atomic Orbital Shapes
Explore 3D probability cloud visualizations of s, p, and d atomic orbitals. Toggle between 1s, 2s, 2px/y/z, 3dz², 3dxy, and 3dx²-y² orbitals. Adjust particle count, opacity, and size to reveal electron density patterns. Quantum numbers update automatically.
Periodic Trends Explorer
Interactive heatmap of the periodic table showing ionization energy, electronegativity, atomic radius, and electron affinity trends. Hover any element to see its exact values and electron configuration. Toggle between four properties and observe the patterns across periods and groups.
Reaction Energy Diagrams
Build interactive reaction energy diagrams with adjustable activation energy, ΔH, and catalyst effect. Switch between exothermic and endothermic reactions, watch the transition state and energy levels update live, and animate a molecule traveling along the reaction pathway.
Central Limit Theorem
Watch the Central Limit Theorem emerge in real time. Choose uniform, right-skewed, bimodal, or normal populations, set sample size n, and take samples one-by-one or in bulk. The sampling distribution of x̄ converges to a bell curve regardless of population shape — see it happen live.
Confidence Interval Simulator
Simulate hundreds of confidence intervals and watch the coverage rate converge to the chosen confidence level. Adjust μ, σ, n, and confidence level (90/95/99%). Green bars capture the true mean; red bars miss it. Builds intuition for the correct long-run interpretation of CIs.
Limits & Continuity
Explore five classic function types — removable holes, jump discontinuities, vertical asymptotes, continuous functions, and oscillating functions. Drag the approach point a and adjust the delta neighborhood to see left/right limits update in real time. Automatically identifies continuity.
Fundamental Theorem of Calculus
Visualize both parts of the FTC side by side: the integrand f(x) with shaded area and Riemann approximation, and the accumulation function F(x) = integral from a to x. Adjust bounds a and b, choose from five functions, and watch exact vs Riemann error update in real time.
Taylor & Maclaurin Series
Watch Taylor polynomial approximations converge to sin(x), cos(x), eˣ, ln(1+x), and 1/(1-x). Adjust the number of terms (1-12) and center point a. Individual terms shown as dashed colored lines; sum shown in purple. Max error and radius of convergence displayed live.
Mitosis Phases
Step through all 6 phases of the cell cycle: Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis. Each phase features a Canvas 2D cell animation, key events list, DNA content tracker, and chromosome count. Use Auto Play to watch the full cycle.
