Simulations: Physics
Build circuits, bend light through lenses and time a pendulum: physics you can change and watch. Each model computes the real numbers, runs on a projector or a touch screen, and lets the class predict what happens before you press play.
Electric circuitsA free circuit builder for class: drag batteries, bulbs, resistors and meters onto a board, see current flow, compare series and parallel, see a short circuit.
Float or sinkA free float-or-sink lab for class: drop wood, ice, an apple, an egg or a steel ball into water, oil, honey or mercury, and see density and buoyancy at work.
Friction and the inclined planeA free friction simulation for class: tilt a ramp, pick ice, wood or rubber, push a box and see static and kinetic friction, force arrows and the slide angle.
PendulumA free pendulum simulation for class: drag the ball, change length, mass, friction and gravity, and compare the measured period with 2π√(l/g).
Refraction and lensesA free optics simulation for class: Snell's law with real angles, total internal reflection, a prism splitting white light, and lens ray diagrams with images.Coming next
