Ohm's Law Wiring Simulator
Wire virtual resistors, power supplies, ammeters, and voltmeters. Manipulate knobs to observe changes in voltage, resistance, and current in real-time.
Force and Motion Simulator
Explore how applied force, mass, friction, and acceleration affect an object's motion through interactive real-time experiments.
Reflection and Refraction of Light
Explore how light rays reflect from a surface and refract as they pass between different media. Investigate angles, refractive indices, Snell's Law, and total internal reflection.
Collision & Momentum
Explore elastic and inelastic collisions, compare motion before and after impact, and verify the conservation of linear momentum.
Current Flow
Investigate the flow of electric charge through circuits, measure current in series and parallel configurations, and explore drift velocity and charge carriers.
Gravity & Orbits
Explore gravitational force and orbital motion in Sun, Earth, Moon, and satellite systems. Investigate velocity, trajectories, mass, distance, and orbital period through live simulation, tests, and problem solving.
Gravitational Force Between Two Masses
Explore Newton's law of universal gravitation using two interactive masses. Change mass and distance, observe equal and opposite forces, run animated collisions, and solve live gravitational-force problems.
Gas Properties
Explore Boyle’s Law, Charles’s Law, pressure, volume, temperature, amount of gas, and the ideal gas equation through particle-based experiments.
Sound Waves
Investigate amplitude, frequency, wavelength and speed while observing how sound-wave properties change in real time.
State of Matter: Basics
Observe particle behavior in solids, liquids and gases and explore how heating, cooling and pressure produce changes of state.
Balancing Act
Explore torque, lever arms and the principle of moments by positioning masses on a beam and creating rotational equilibrium.
Resistance in a Wire
Investigate how wire length, cross-sectional area, material and resistivity determine electrical resistance.
Thermal Energy and Heat Transfer
Select energy sources (Sun or Bicycle) and convert energy to power output devices like a Fan or a Bulb. Test yourself with live targets and interactive input controls.
Rutherford Scattering
