Ecosystem Simulation v2
About this simulation The length of the red bar shows the vitality. It gradually decreases with time. When the vitality is zero, it naturally dies. The green bars show stamina (nutritional status). If it is short, … more
Magnetic Field around Magnet(or Earth)
Magnetic field around magnet The space where the magnetic force of the magnet acts is called a ‘magnetic field.’ The direction of the magnetic field is determined in the direction indicated by the N pole of … more
Spectrogram
This simulation analyzes the sound around you and displays it as a spectrum. The simulation works by recognizing the surrounding sounds. In the case of PC, please grant permission to use the microphone. Voice data is … more
Gravity Simulator
This simulation … Applied a geocentric coordinate system. Air friction is ignored. Covers fall and orbital motion due to Earth’s gravity. (However, the same can be applied to other celestial bodies.) Gravity Objects with mass exert … more
Iris and Ciliary Body
Iris muscles In the iris, the ‘Iris sphincter muscle’ constricts the pupil, and the ‘Iris dilator muscle’ enlarges the pupil. Both muscles work in reverse, controlling the size of the pupil. Ciliary body connected to the … more
Buoyancy Experiment
The fluid in the beaker is water, and its density is assumed to be 1 g/mL. The volume of the object is assumed to be 100 mL. Buoyancy When we wear a life jacket, our bodies … more
Optical Experiment Simulator
It is an optical experiment simulator consisting of a slit laser, lenses, and mirrors of various shapes. You can experiment by dragging the tool you want. Slit lasers are rotatable. Try dragging the red icon behind … more
Free Fall Experiment
This simulation allows you to measure speed as a function of fall height. Free fall movement All objects on Earth are affected by gravity. If there were no friction with air, the speed of any object … more
Same Circuit
Same Circuit In an electric circuit, voltage occurs at both ends of the cell. The place where this voltage is released is called ‘load’. In typical textbooks, ‘load’ is often replaced by a light bulb or … more
Multi Alarm Program
If you enter the time as text, an alarm will sound automatically. Current Time Edit (Hour、Minute、Chime number) Setting results If you enter the alarm schedule line by line in the yellow notepad, you can view the … more
Leyden Jar
Leyden Jar The Leyden Jar is a tool (capacitor) created in the 18th century for storing static electricity. The Leyden Jar is made of glass, with metal foil surrounding the inside and outside of the bottle. … more
