A collection of interactive simulators built to support the teaching and learning of physics. Adjust the sliders to change the conditions and see how each phenomenon responds, making abstract concepts easier to grasp and explore in the classroom or at home.
Drag two vectors or set their magnitude and angle, and see the resultant vector, its components, and the triangle/parallelogram construction in real time.
Open โChoose a projectile, set the launch angle and speed, and watch the trajectory. Toggle air resistance to see how drag changes the path.
Open โPlace bugs on a spinning disc to explore velocity and acceleration vectors, then watch x- and y-direction graphs of displacement, velocity, and acceleration over time.
Open โExplore elliptical orbits, equal-area sweeps, and the Tยฒ โ aยณ harmonic law with real solar-system planet data.
Open โFire a cannon from a tall mountain and see how launch speed decides whether the shot falls, orbits Earth, or escapes โ Newton's thought experiment for orbital motion.
Open โRelease a ball down a ramp so it strikes a target ball at an angle, record where both land on carbon paper, and check that momentum is conserved in each direction.
Open โSimulators covering electric fields, magnetic fields, and circuits will be added here soon.
Watch gas molecules bounce elastically off the walls of a wavy container, with no molecule-molecule collisions, and see how average speed and wall-collision rate stand in for temperature and pressure.
Open โCompress, heat, or expand a gas in a piston and watch Boyle's, Charles's, and Gay-Lussac's laws play out through particle collisions and live pressure-volume-temperature graphs.
Open โAdjust the focal length, object distance, and object height, and watch three principal rays locate the real or virtual image.
Open โAdjust the wavelength and slit width to see how a wave spreads after passing through a single slit, and compare the spread with the diffraction condition d sin ฮธ = mฮป.
Open โWatch two pulses traveling toward each other overlap, and see constructive and destructive interference happen in real time.
Open โTwo waves travel along the same string. Change their amplitudes and phases and watch, point by point, how the phase difference decides constructive or destructive interference and the resultant amplitude.
Open โSee the standing wave, nodes, and antinodes that form when two waves of equal wavelength and amplitude travel in opposite directions.
Open โClick anywhere on the overlapping wavefronts from two point sources to find where interference is constructive or destructive.
Open โAdjust the coating thickness and light wavelength to see how reflections off the top and bottom of a thin film cancel through destructive interference.
Open โShake a string by hand, with an oscillator, or with a pulse and watch waves travel and reflect at fixed, free, and open ends. Change tension and density, build standing waves through resonance, and release normal modes that keep vibrating with no energy supplied.
Open โRecreate the 1887 Michelson-Morley interferometer experiment and see how aether wind speed, arm length, and rotation angle affect the fringe pattern.
Open โAdjust the light's wavelength, intensity, and applied voltage to explore the conditions for electron emission and the stopping voltage.
Open โCalculate and visualize the photon wavelength and spectral line emitted as an electron transitions between orbits in Bohr's model.
